I have a client/server app which I have been developing on a single PC. Now it needs two serial ports, so I borrowed a PC from a friend.
When I build my app and try to run or debug it (whether in the Delphi IDE or from Windows File manager), it errors "The application was unable to start correctly (0xc000007b)".
Googling doesn't bring up much, but seems to indicate that this is nothing Delphi specific and happens with other apps. It seems to be caused by calling into a 32 bit DLL from a 64 bit app or vice versa.
both PCs are Windows 7, 64 bit
both have Delphi Xe2 starter edition which can only handle 32 bits
The app runs fine on my PC, but not on my friend's
Other Delphi apps run just fine on both PCs
Can anyone give me a hint as to how to track this down?
Normally we get the 0xC000007B error-code (which means STATUS_INVALID_IMAGE_FORMAT), if:
If a 32-bit app tried to load a 64-bit DLL.
Or if a 64-bit app tried to load a 32-bit DLL.
Or if a 64-bit app tried to run on a 32-bit Windows.
To really know, I would suggest to test whether there is a problem between your application and its dependencies using dependency walker
Note that all you need to do is open your App using said tool, and issues appear as red log-entries at buttom of screen.
(At least, at time of writting, namely 2022)
Also, make sure you run the correct version of Dependency Walker, for example, the x86 version will display incorrect results when openning x64 binaries.
A load time dependency could not be resolved. The easiest way to debug this is to use Dependency Walker. Use the Profile option to get diagnostics output of the load process. This will identify the point of failure and should guide you to a solution.
The most common cause of this error is trying to load a 64 bit DLL into a 32 bit process, or vice versa.
I tried all the things specified here and found yet another answer. I had to compile my application with 32-bit DLLs. I had built the libraries both in 32-bit and 64-bit but had my PATH set to 64-bit libraries. After I recompiled my application (with a number of changes in my code as well) I got this dreaded error and struggled for two days. Finally, after trying a number of other things, I changed my PATH to have the 32-bit DLLs before the 64-bit DLLs (they have the same names). And it worked. I am just adding it here for completeness.
It is a missing dll.
Possibly, your dll that works with com ports have an unresolved dll dependence.
You can use dependency walker and windows debugger. Check all of the mfc library, for example. Also, you can use nrCommlib - it is great components to work with com ports.
It has been mentioned in earlier answers that using dependency walker is the way to go, in my case (my application keeps failing with the error code), dependency walker showed a few dll that are NOT relevant!
Finally figured out that I can run profiling by going to "profile" menu and it will run the application and stop at the exact dll that's cause the problem! I found out a 32bit dll was picked because of path and fixed it.
I experienced the same problem developing a client-server app using Microsoft Visual Studio 2012.
If you used Visual Studio to develop the app, you must make sure the new (i.e. the computer that the software was not developed on) has the appropriate Microsoft Visual C++ Redistributable Package. By appropriate, you need the right year and bit version (i.e. x86 for 32 bit and x64 for 64 bit) of the Visual C++ Redistributable Package.
The Visual C++ Redistributable Packages install run-time components that are required to run C++ applications built using Visual Studio.
Here is a link to the Visual C++ Redistributable for Visual Studio 2015 .
You can check what versions are installed by going to Control Panel -> Programs -> Programs and Features.
Here's how I got this error and fixed it:
1) I developed a 32 bit application using Visual Studio 2012 on my computer.
Let's call my computer ComputerA.
2) I installed the .exe and the related files on a different computer we'll call ComputerB.
3) On ComputerB, I ran the .exe and got the error message.
4) On ComputerB, I looked at the Programs and Features and didn't see Visual C++ 2012 Redistributable (x64).
5) On ComputerB, I googled for Visual C++ 2012 Redistributable and selected and installed the x64 version.
6) On ComputerB, I ran the .exe on ComputerB and did not receive the error message.
I recently had an issue where I was developing an application (that used a serial port) and it worked on all the machines I tested it on but a few people were getting this error.
It turns out all the machines that the error happened on were running Win7 x64 and had NEVER ONCE been updated.
Running a Windows update fixed all of the machines in my particular case.
Actually this error indicates to an invalid image format. However, why this is happening and what the error code usually means? Actually this could be appear when you are trying to run a program that is made for or intended to work with a 64 bit Windows operating system, but your computer is running on 32 bit Operating system.
Possible Reasons:
Microsoft Visual C++
Need to restart
DirectX
.NET Framework
Need to Re-Install
Need to Run the application as an administrator

This may be a case where debugging the debugger might be useful. Essentially if you follow the instructions here you can run two ide's and one will debug into the other. If you un your application in one, you can sometimes catch errors that you otherwise miss. Its worth a try.
I have seen the error trying to run VC++ debug executable on a machine which did not have Visual C++ installed. Building a release version and using that fixed it.
In my case the error occurred when I renamed a DLL after building it (using Visual Studio 2015), so that it fits the name expected by an executable, which depended on the DLL. After the renaming the list of exported symbols displayed by Dependency Walker was empty, and the said error message "The application was unable to start correctly" was displayed.
So it could be fixed by changing the output file name in the Visual Studio linker options.
You can have this if you are trying to manifest your application that it has a dependancy on the Microsoft.Windows.Common-Controls assembly. You do this when you want to load Version 6 of the common controls library - so that visual styles are applied to common controls.
You probably followed Microsoft's original documentation way back from Windows XP days, and added the following to your application's manifest:
<!-- Dependancy on Common Controls version 6 -->
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="X86"
publicKeyToken="6595b64144ccf1df"
language="*"/>
</dependentAssembly>
</dependency>
Windows XP is no longer the OS, and you're no longer a 32-bit application. In the intervening 17 years Microsoft updated their documentation; now it's time for you to update your manifest:
<!-- Dependancy on Common Controls version 6 -->
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="*"
publicKeyToken="6595b64144ccf1df"
language="*"/>
</dependentAssembly>
</dependency>

The main problem, of course, is that a DLL file is missing, or, even more likely, corrupt. If this is the case, then I have some pretty good ideas (especially if you've downloaded and installed a DLL manually!)...
TLDR: Delete every manually copy/pasted DLL you've done, uninstall old redistributable installs, and reinstall new redistributables for both 32-bit and 64-bit installs.
What To Do
This solution of copying/pasting missing DLL's into system32, etc., used to work since I can remember in the 1990's, but it doesn't seem to work anymore (2020). So if you run into this problem recently, I suggest:
Within windows\system32 and windows\SysWOW64, delete all files that match ms*.dll, that the operating system will allow you delete as admin.
Uninstall all Visual C++ Redistributables that you have with Windows. This prevents the "You already have this!" dialogue showing up upon reinstall, as detailed in the next step when we re-install.
Reinstall the 2015-2019 Visual C++ Redistributable from a regularly available download site. If this does not work, download and install the others, but personally, the 2015-2019 covered everything for me. Regardless of your machine, install both x32 and x64 packages! (All Download Links: Collected VC++ Download Links; MSVCR120.dll Fix; MFC140U.dll Fix.)
How You Know It's Working
There's a lot of variation in coders experiencing this, so, the idea that there's one single, possible solution is often discarded, but let's be positive!
If deleting the matching ms*.dll files worked, then you will no longer get an error about error code 0xc000007b. Instead, you'll get a message about a missing .dll. This tells you that you're hitting the right code path!
If installing the redistributable works, then certain popular, DLL files should appear in the above-mentioned system32 and SysWO64 folders. For instance: MSVCR120.dll, MSVCR140.dll, MSVCR100.dll, MSVCP100.dll, MSVCP120.dll, MSVCP140.dll, and friends.
Last, Possible Best Chances
Sometimes things don't work according to plan (as we all in the Windows world know). You can also try the following!
Open the "Turn Windows Features on or off" tab in Windows (supported in Windows 8-10). Uncheck the .NET Framework installations. You'll see a small installation go by.
Restart the system. Go to the above feature again, recheck .NET Framework, and click "okay". If this works, you'll see a "installing and updating .NET framework" message that takes maybe a minute or so to go by. Once this is done, I recommend a reboot again.
Good luck!
Just solved this problem for my personal project (thanks to Dries for that). For me it was because the project path was too long. After saving the .sln to a shorter path (C:/MyProjects) and compiling from there it ran without the error.
Also download and unzip "Dependencies" into same folder where you put the wget.exe from
http://gnuwin32.sourceforge.net/packages/wget.htm
You will then have some lib*.dll files as well as wget.exe in the same folder and it should work fine.
(I also answered here https://superuser.com/a/873531/146668 which I originally found.)
I just ran into this issue. I searched for "C++" under my "Apps & Features" in Windows 10 control panel and noticed that some kind of update had just run a few days prior and installed VC++ Redistributable 2012-2017. The app that was running into the error message only required VC++ 2010. I uninstalled all of them and then reinstalled just 2010 x86/x64, and the error went away and the application functioned as expected.
That can happen if for some reason a x86 resource is loaded from a x64 machine. To avoid that explicitly, add this preprocessor directive to stdafx.h (of course, in my example the problematic resource is Windows Common Controls DLL.
#if defined(_WIN64)
#pragma comment(linker, "\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='amd64' publicKeyToken='6595b64144ccf1df'\"")
#endif
It is possible that you have multiple versions of the dll(s) on your system. You can search your system to find out. The issue may be solved by simply changing the order of the directories in your path. This was my issue. (Cannot run Qt Creator GUI outside of Qt. "The application was unable to start correctly (0xc000007b)" error)
I ran into this issue when fetching code from my repository and compiling on a new machine. Copying over the entire repository and then compiling resulted in an executable which worked. Turns out a 32bit DLL accidentally wasn't checked in. As the people above state, use "Dependency Walker" to figure out where it goes wrong.
To make it more clear what to look for see the below screenshot, with in the background the exe trying to load the wrong DLL (notice the '64') resulting in "the application was unable to start correctly 0xc00007b" and in the foreground the exe which was simply copied over (which included the correct DLL).
I came here when I was searching for: "golang Windows (0xc00007b)"
I have an app written in Golang, which uses iconv. It worked on my machine, but not in someone else's machine.
The first error was the missing DLL: libiconv-2.dll, so I guess they downloaded it on the internet but it was the 32 bit and not 64 bit version, so the 0xc00007b error appeared.
I searched the DLL on my system but I did not have success until I searched on MinGW 64 path which in my case is: C:\msys64\mingw64\bin
The solution was to distribute the DLL with the .exe, which was in the MinGW folder.

Normally we get the 0xC000007B error-code (which means STATUS_INVALID_IMAGE_FORMAT), if:
If a 32-bit app tried to load a 64-bit DLL.
Or if a 64-bit app tried to load a 32-bit DLL.

i have just my Firefox reinstalled and after this(maybe it was not the reason),
my visual studio Project compiled only with 9.0.30729.6161 VC++ Runtime DLL.
Until yesterday it always compiled with 9.0.30729.8387 VC++ Runtime DLL.
Because of this (or maybe other reason), now i cannot start my Project.exe.
Nothing is changed in source-code. Project-Property and all other things are also unchanged.
I just get the error number 0xc000007b suddenly.
How can i fix this?
It was because of an 32bit DLL, which should not be loaded for my 64bit Project.exe.
I have found this with Process Monitor.
I don't know why, but anyway is the "path" is changed and the 32bit DLL(which has the same name with 64bit DLL) is loaded..
If you have the same Problem, check whether there is a problem between your application and its dependencies using dependency walker.
Entered the answer in another place, but figure it could be helpful for folks who badly need some help:
It has been mentioned in other answers that using dependency walker is the way to go, in my case (my application keeps failing with the error code), dependency walker showed a few dll that are NOT relevant!
Finally figured out that I can run profiling by going to "profile" menu and it will run the application and stop at the exact dll that's cause the problem! I found out a 32bit dll was picked because of path and fixed it.
-Turn off your antivirus software before starting the installation.
-Accept any additional software offered during installation process, since it may be crucial for running your application properly. You can skip things such as search bars, antivirus scanners, registry cleaners and the other software which isn’t directly related to the application.
-Install an application to the system partition (C:). Although this shouldn’t matter, it’s been proven that some apps may return an error if installed on a logical partition.
There is more than one way to solve it. This link might also be helpful.

Im trying to deploy a C++ AMP application to another Windows 7 machine.
I have tried to include the vcamp110.dll in the same folder, and also compiled with /MT do get rid of dependency on msvcp110.dll and msvcr110.dll.
Also tried both x64 and win32 release of the application.
On the computers i have tried it on whitout VS11 installed, the program stops responding.
I tried to do a simple test with the hello world application and i have the same problems there.
The files can be downloaded from here http://www.2shared.com/file/IofZlrJs/amptest.html (source, binary and the dll).
Any suggestions to how this can be fixed?
Deployments like the one you tried are definitely supported – full details here:
http://blogs.msdn.com/b/nativeconcurrency/archive/2012/03/12/deploying-apps-built-with-c-amp.aspx
There are a few things you can do to diagnose the issue you are facing yourself:
The bitness of vcamp110.dll has to match the bitness of your app, so 32bit for one means 32bit for the other.
Ensure that there are no other instances of vcamp110.dll in some central location (e.g. system32)
Attach a debugger and see what DLLs are loaded and what exception gets thrown.
Most important of all, for all your apps, surround your parallel_for_each call with try…catch to see what runtime_exception you are getting. More on C++ AMP exceptions can be found here: http://blogs.msdn.com/b/nativeconcurrency/archive/2012/02/01/c-amp-runtime-exceptions.aspx
For the specific repro you shared, we tried that under the debugger on a clean Windows 7 machine and indeed a rutime_exception is being thrown: “The binary for the parallel_for_each is incompatible with this version of runtime.”, which indicates a mismatched runtime version (either mixing bitness or mixing Developer Preview with Beta or something like that).
I've written a C++ console application in Visual Studio 2019 and am trying to deploy it to another windows laptop. Both laptops are up-to-date with 64 bit Windows 10, and my target laptop has installed/up-to-date .NET Framework, vc_redist.x64.exe, and DirectX.
In terms of deployment method, I followed this Microsoft walkthrough word for word, with the added step of ensuring that my newly created "setup" project was also targeting x64 platform, since some of the external libraries in my code required x64. The resulting "setup" .exe/.msi pair work as planned on the source laptop - installs and runs with no frills required.
Installation goes fine on the target laptop, but launching the program gives the error mentioned in the title of this post. After a few hours of trying to figure it out, I think I have an idea where the problem is coming from, but first, I'll share what I've tried, which is basically every recommendation found by googling this error code:
clean boot
SFC scan
chkdsk c: /f /r
repairing/fresh installing all of the frameworks mentioned in the first paragraph
running both the application installer and the installed application as administrator
restarting laptop and reinstalling application after all of those changes
What I think is the root of the problem:
In the setup/deployment project in VS, three of the "detected dependencies" (MSVCP140D.dll, ucrtbased.dll, VCRUNTIME140D.dll) have filepaths through …\System32\ rather than the identical dependencies that could be found in …\SysWOW64. The other two detected dependencies are external 64-bit DLLs (which is why I specified my entire project to x64). When I run my application through Dependency Walker, it agrees that the three formerly mentioned dependencies are "wrong CPU type", while the two latter ones are fine. This scenario does not, however, explain to me why install/run (outside of VS) works fine on the source laptop (shouldn't it not work if VS is packaging a mix of 32 and 64 bit dependencies?). In fact, running the application through Dependency Walker on the source laptop reveals the exact same thing as on the target laptop - the same 3 dependencies are "wrong CPU type", yet the application runs here.
I do not see an option in VS to change the "setup" project to read the 64 bit filepath. I have tried manually swapping in the 64-bit DLLs at various stages (including restarting the computer between DLL swap and application run), which did not seem to have any effect. In fact, I tried replacing the 3 relevant DLLs in the System32 folder with the DLLs from the SysWOW64 folder (my idea of a cheap workaround for not being able to change the filepath - just change the file) and this just caused me to get the same error on my source laptop as I had been getting on my target laptop.
All of this stuff is relatively new to me, so please let me know if I'm foolishly overlooking some fundamental detail with my process/project - at this point it would be nice if that were the case and this is easy to fix.
Wrote this before I noticed the above comment had already answered.
Just leaving it in.
Debug Binary: Looks like you have deployed a debug version of your binary (The D in the file name: MSVCP140D.dll). Try to compile in Release mode and deploy the new binary.
Cause: Debug binaries generally need the debug-versions of the VCRedist binaries to exist on the box you try to run the binary - they are only available on developer PCs with the SDK (and / or Visual Studio) installed. That error message: 0xc000007b means "STATUS_INVALID_IMAGE_FORMAT".
Tips: There are some resource links here and some tips on how to debug deployment problems.
