I have recently wanted to build a dll plugin for a program. Problem is, the program is 32bit, but by default my Visual Studio 2012's C++ compiler creates 64bit binaries, and I don't know how to change it - I've found the Configuration Manager and tried to create a new platform but there's only x64 as an option.
Am I trying to set the target architecture in the wrong place or what? Is there an update or something I can download so that I can create my dll? Is there a compiler switch that I can set somewhere?
Hope this screen helps:
To build for 32 bit architecture, you have to open project properties window, and then Linker options.
Set the value of Target Machine option to MachineX86.
Check the Build Configuration (Build -> Configuration Manager), and ensure that your DLL project for 32-bit is selected.
Check the linker settings, and ensure correct path is given.
After build, check that .DLL is produced at correct path, and is 32-bit (should be!).
You can use Dependency Walker to check if DLL is 32-bit or 64-bit.
You also didn't mention if /clr option is used with this DLL or not. With /CLR, managed binary is produced. Though this option wouldn't alter bit-ness of the binary, you can just check if this is the case.

I created a client server application in C++ using Visual Studio.
Now I want to run the client EXE file on another computer (which doesn't have Visual Studio installed),
but when I try run the EXE file, it gives the following error message:
This application has failed to start because the application
configuration is incorrect. Reinstalling the application may fix this
problem.
How can I run the EXE file without installing anything on the computer?
Applications built with Visual Studio depend on Visual C++ Redistibutable (VCRedist). When the program is being linked dynamically, then your binaries will need
MSVCR**.dll (Microsoft C Runtime Library).
On MSDN, there is a nice article called Redistributing Visual C++ Files (for Visual Studio 2008), that states that there are Potential run-time errors in case that required Visual C++ library is not installed:
you may get one of the following error messages depending on the version of Windows on which you try to run your application:
The application failed to initialize properly (0xc0000135).
This application has failed to start because the application configuration is incorrect. Reinstalling application may fix this problem.
The system cannot execute the specified program.
Basically you have two options:
The simplest possible solution is to change the dynamic linking of runtime libraries to static linking. Go to project properties and under C/C++ → Code Generation you will find Runtime Library option. You need to change it from Multi-threaded DLL (/MD) to Multi-threaded (/MT).
Another possible solution is to make sure that the right version of Microsoft VC++ Redistributable Package is installed on the target machine.
But your application might depend on other DLL files as well. In case you want to find out what are the dependencies of your program, there is a great utility called Dependency Walker that will help you in this and many other situations :)
Background:
C++ applications need run-time assemblies (DLL files) to run in any Windows computer.
Normally these run-time assemblies are located at C:\Windows\Winsxs directory.
All the Windows operating systems by default comes with several run time assemblies.
But if your application is developed in a newer version of the run-time assembly environment, the target computer also needs the same version of the run time to exist there.
When you're installing Visual Studio, most newer versions of the run-time assemblies comes to your computer.
Solution:
Finally by anyway the target computer should have the exact run time assemblies. There are a few ways to do this (for more details search each in Google).
Statically link run-time assemblies with your application (troublesome for large application).
Install the C++ redistribution environment on the target computer (the easiest way).
Creating a setup project to deploy the run-time on the target computer when installing the application (not bad).
For deploying run-time assemblies as private assemblies (professional), see here for more details
Conditions:
You must not use .NET framework in your application.
You must not use the common language run-time support for your application
I deployed my program in release instead of debug, and the EXE file now works on the other computer.
I haven't seen that specific error before. Usually it's an error around a missing DLL (Windows redistributable). Assuming there isn't actually a problem with the configuration, you have two choices:
Change the compile mode from Multithreaded DLL to Multithreaded. This can be done from the C++ section of project properties under code generation. In multithreaded mode your binary will be statically linked against the Windows redistributable. This is probably what you want.
Install the Windows redistributable on the target machine. This probably isn't OK, because you state that you don't want to install anything on the target machine.
A warning about option 1: Different versions of Windows have different versions of the redistributable. It's possible to encounter a highly specialized environment in which a statically linked program will not behave as expected.
It look like you're missing some DLL files. Be sure to copy appropriate DLL files along with EXE file.
I am running Visual Studio 2019 and I found a very helpful configuration property to address the problem of moving a simple application to another computer without an installation package.
Open the project Property Pages.
Choose which configurations this change should apply to, I used “All Configurations”.
In the left-hand window click to expand the top node called “Configuration Properties”.
Click on "Advanced". In the right-hand window look for the property called “Copy C++ Runtime to OutDir” and set that to “yes”.
Click OK to close the Properties window.
Rebuild your project. All the necessary dlls will be copied to the project’s output directory. Copy your exe and all dlls to another computer. The exe should find everything it needs to run.
I've got a managed c++ dll, and it builds fine in x86 format. However, when I change the format to x64 in configuration manager, it won't recognize .Net namespaces, like System etc.
What else should I change to be able to build the 64-bit version of the app?
I'll need to be able to build the app for x64 and for x86.
When you changed your project to target x64, the settings that tell the compiler to target the .NET Framework obviously didn't get transferred over.
Check your project's properties to ensure that all of the x64 settings match with the x86 settings.
More specifically, you're looking for the "Common Language Runtime Support" property. On recent versions of Visual Studio, this should probably be set to Common Language Runtime Support, Old Syntax (/clr:oldSyntax) for Managed C++.
You would create an 'x64' configuration there is a second drop down box for 'copy settings from'. That also has to be properly set to copy setting from your other configurations.
But since you have already done that, perhaps all your assembly referenences didn't copied over to your 'x64' configuration. Have you checked in your x64 project settings to see if they are there? Open up your project settings and select:
Common Properties -> Framework and References
Then make sure you have a reference to System (At least)
I have a C++ .exe compiled with /MDd (since I can't use CLR with /MTd). At first I was getting couldn't find x.dll that is installed when installing the VC++ runtime. After I installed the VC++ 2010 runtime, I still get the error. I've verified that the .dll it's looking for (msvcpsomethingd.dll) is located in the correct folder ([SystemDrive]\Windows\system32). Has anyone run into this problem before?
How to deploy debug CRT .dlls
How to deploy CRT .dlls in general to the application local folder
The short answer is you have to explicitly install the CRT debug runtime for VS 2010 with a custom setup project on the target machines OR ensure the CRT .dlls for the platform are in the same folder as the application.
You will have to explicitly install the CRT if you are using multiple versions of the debug CRT (i.e., x86 and x64).
The best way to solve these issues is to use the depends.exe tool. Profile the program and it will tell what you are missing.
Compile with release mode and run on different PC. It seems like one/more of your DLLs are compiled using Debug build or dependencies.
It could be your referenced library as well..
Ensure that correct Redestributable of VC++ 2010 is installed:
32-bit OR 64-bit, depending on your application, not as per target OS.
Appropriate RTM or Service Pack version.
When I try to open released .exe file (which I wrote in Visual Studio 2008) in VMWare Workstation 6.5 with Windows Server 2008 32bit OS, got "The application has failed to start because its side-by-side configuration is incorrect." error all time even if the code is;
#include <stdio.h>
int main ()
{
printf ("HELLO\n");
return 0;
}
Is anyone faced that king of problem or does know how to cope with it?
You probably forgot to deploy the runtime support DLLs or copied the Debug build of your program. For a small program like this without DLLs that export C++ classes or pointers it is better to link the static version of the CRT. Project + Properties, C/C++, Code Generation, /MTd. Repeat for the Release configuration, now choose /MT.
It has nothing to do with VMWare -- it has to do with not having the correct side-by-side assemblies for the C runtime installed. You need to know which ones you require, and then install the runtime. You can also control it with a manifest.
There is some info here
http://en.wikipedia.org/wiki/Side-by-side_assembly
One easy way (for C/C++ programs) to get around this is to change to linking to the C-runtime statically. Go to your project properties, then Code Generation, and choose static linking for the C Runtime. Then you won't have a dependency on the runtime dlls. All libraries you might be using need to be linked this way for it to work.
I generally get this error if the C/C++ runtime that the program was built with was not installed in the VM. You can download the CRT for Visual Studio 2008 SP1 at Microsoft's website. Make sure to download the correct version of the CRT based on the versions of Visual Studio used to build the app.
I've got a minimal app I just created, using VS 2008 SP1 on Vista x64. Its a Console app, created with the wizard, no MFC or anything, I'm building it in 64bit.
When I run the debug exe, on my development box, by pressing F5 in Visual Studio 2008, I get this error:
TestApp.exe - Unable To Locate Component
This application has failed to start because MSVCR90.dll was not found.
Re-installing the application may fix this problem.
OK
I don't get this error when I run the release exe, it works as expected.
This problem started when I added some include dependencies on iostream and fstream and started calling some winsock API calls.
Any suggestions?
UPDATE: I copied msvcr90.dll (not msvcrd90.dll) into the correct folder, and now I get a different error:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: [snip]...
R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
OK

You application is using the DLL CRT runtime. The machine you want to run it on requires the installation of the debug CRT runtime dll's (which is a pain in the ass...). I think the better solution is to change the compile options to use the static linked CRT runtime (that means the runtime is linked into your application instead of using the DLL version).
In visual studio go into the Properites for your project then select the Configuration Properties / C++ / Code Generation and change the "Runtime Library" from "multi-threaded debug dll" to "multi-threaded debug".
You may like to do the same for the release build as well because some versions of the OS will not come with the V9 release CRT libraries pre-installed, or you can include the v9 release crt dll as part of your install.
How are you running the release exe (Ctrl+F5 in the IDE)? You should set the Runtime Library to the same thing you are setting the release exe.
Are you linking your debug mode program to a release mode library? You mention this error in a comment:
Error 13 error LNK2005: memmove already defined in LIBCMTD.lib(memcpy.obj) MSVCRT.lib DataEngineSocketsAPI
What that looks like to me is you have a library named DataEngineSocketsAPI that links to MSVCRT.lib, which defines memmove(). But, your exe links to libcmtd.lib, which also defines a different (debug mode) version of memmove().
Third-party (e.g. your own) libraries must have debug and release versions too, and you must use the one appropriate to the mode you're building your exe for.
The Debug exe is linked to the headers for the debug runtime library, MSVCR90D.dll. You need to make sure that dll is in the path. Static linking is, as Shane says, a viable option, but the typical solution is to deploy the dependant dlls with the exe. Statically linking everything leads to bloated exes and lots of duplicated copies of runtime libraries.
Seeing your edit, the problem is certainly the msvcr90d.dll, but it needs to be deployed correctly in the WinSXS folder. You might be able to re-install the service pack for VS 2008 and get it to redeploy.
Thanks again for all the help with this. It turns out I'd just made a mistake and not noticed that a library I was using was statically linked against a different version of the MSVC runtime. That was causing on end of problems.
See this link
http://www.insidercoding.com/post/2008/07/21/Debugging-issues-with-MSVCR90DLL.aspx
You need (for debug mode only) to ignore on the link input tab MSVCRT; MSVCR90; as you want to be using the debug version of the CRT.
I can confirm this problem: letting Visual Studio 2008
create the project (Visual C++/Win32 Console Application)
and pressing F5 will display that error.
There is a simple solution:
Turn incremental linking off. HOWTO: open properties page
for the project. Set Configuration
Properties/Linker/General/Enable Incremental Linking to "No
(INCREMENTAL:NO)".
