I've just recently started out with Qt and created a simple Qt Widgets application. When I build and run the application (even if I make a fresh project with no new code in it) I get the following error messages:
mincore\com\oleaut32\dispatch\ups.cpp(2128)\OLEAUT32.dll!74445072: (caller: 7444FE4F) ReturnHr(1) tid(188) 8002801D Library not registered.
mincore\com\oleaut32\dispatch\ups.cpp(2128)\OLEAUT32.dll!74445072: (caller: 7444FE4F) ReturnHr(2) tid(188) 8002801D Library not registered.
My Qt install and Windows are both up to date. I've been searching for a solution for a couple hours now and I can't find anything even remotely relevant to the problem online... Has anyone else anywhere had a similar issue?
Update:
I just completely removed Qt from my PC and did a fresh install and I am still getting the same messages.
Ugh. This problem wrecked my sunday.
I'm on QT 5.9.1, Windows 10, Surface Book.
I tried reinstalling windows, didn't work. I tried reinstalling Microsoft Runtime, didn't work. Reinstalled QT in a million different ways, didn't work.
So I was on the latest updates, and checked my oleaut32.dll version - 1.1.15063.0. According to an old forum post I found around, this error can be caused by the application requesting a newer version of oleaut32.dll than you have. So I jumped onto the insider preview versions (picking the slow ring) and was upgraded to release 10.0.16251 which also upgraded my oleaut32.dll. Fixed it, no error anymore. QT creator finally works.
I guess QT requires you to be on beta windows now?

I’m having difficulty getting the sample code for tws api running. I’ve successfully run it on a borrowed laptop but the same version fails on my own windows 10 laptop. When running on Release mode in Win32, I get the popups
The code execution cannot proceed because biddll.dll was not found. Reinstalling the program may fix this problem. and The procedure entry point ?cancelOrder#EClient##QAEXJ#Z could not be located in the >dynamic link library C:\Eclipse-workspace\TWS >API\samples\Cpp\TestCppClient\ReleaseTestCppClient.exe.
I’ve read through several questions similar to this. I’ve tried installing the Visual C++ Redistributable for Visual Studio 2022 for both x86 and x64 from here: https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170. I’ve tried loading biddll.dll from another folder but it gives the message “Module was built without symbols.”. I’ve run “sfc /scannow” for broken files. The issue persists. biddll.dll still seems to not be anywhere in the system files or the API files. The only version is the one I copied from another version of the project.
Thanks for your suggestions. I uninstalled TWS API and reinstalled it. I made sure to build for Release. It sounds like there was a mismatch between some debug libraries and it started pulling them instead. There may have been some unexpected behavior from installing several versions while troubleshooting as well.
I'm attempting to install Qt 5.11.2 and Qt creator through the .run installer found on their website.
I can get through the installer just fine, but when the installer finishes downloading and starts installing to my filesystem it always hangs at the exact same point.
Specifically, when its writing /Qt5.11.2/Src/qtwebengine portions. However I don't believe this is the issue because even if I uncheck the box for web engine before installing it still crashes at a specific point somewhere else. Ubuntu gives me the option to force close every time, I have waited to make sure it doesn't come back but it never does.
Can anyone offer any help? I'm not sure if maybe i'm missing some dependencies the installer needs or there's just something wrong with Qt's installer?
Thanks.
I just needed to let it sit for 20 minutes.
I'm new to Qt, but have been working with Visual studio for C/C++ development for a few years. Now I'm trying to build a GUI for my project. I installed Qt 5.11.0 and the Qt VS Tools on both my work computer and home PC. At work I can build and run my project with the VS debugger, however on my home system I can build but can't run either with VS debugger or simply launching the app. I tried in release and it runs fine.
The error I'm getting is :
The code execution cannot proceed because VCRUNTIME140D_APP.dll was not found.
I get 4 of these, the first two want VCRUNTIME, the second two want MSVCP140D_APP.dll.
Solutions I've tried so far :
Uninstalled Win SDK and reinstalled
Uninstalled VS2017 and SDK and reinstalled
Searched System32, SysWOW64 and VS install directories - found msvcp140d.dll and vcruntime140d.dll, but no _app.dlls
Does anyone know what these are included with and where to get them? I can't figure out why I have them on my work computer but not at home. I have the same VS updates, same Qt version, and SDK on both systems.
Using :
Visual Studio 2017 v15.7.1
Qt 5.11.0 - msvc2017_64
I suppose I can just copy the .dll's from my work pc and drop them in the appropriate locations on the other, but I'd like to know what they should have been installed with so I can have the same setup on both systems.
Edit:
I also tried changing the platform toolset to VS2015 with Qt versions msvc2015_64 and winrt_x64_msvc2015
I found this post concerning the same missing _app.dll files. There wasn't any answer there, which is why I tried reinstalling the SDK in the hope the missing files were included there.
Edit 2:
I just scanned my entire system at work and it turns out that I don't have the missing .dll there either. That tells me that there is a difference in the project properties or configuration between the two. I use git for source control, and I am currently the only contributor to this project. When I try to build and run just the example from the getting started guide I have the same problem at home with missing _app.dll files, however it works fine at work. I'm totally confused now, and any hints are greatly appreciated.
Solution:
After trying for a couple of hours making new solutions etc. I decided to delete the entire build folder and put fresh copies of all the dependencies into it. My project now runs fine in debugging mode.
I'm fairly certain that when I originally copied the Qt .dll files into it I must have grabbed them from one of the winrt folders rather than the msvc2017_64 folder. To test I replaced the working .dll files with those from the winrt_x64_msvc2017 folder and sure enough the same errors again. So, this was a dumb mistake on my part, but hopefully it'll save someone else a lot of hair-pulling in the future.
I've looked for an answer during a few days and I haven't found anything similar anywhere;
I downloaded Qt from the official website, installed it and apparently compiling is fine. But whenever I try to execute (Ctrl+R) any app, even the basic one which only displays a window or widget, QtCreator itself crashes. No error message, nothing, just crashing.
I've tried to redownload and reinstall it a few times with different settings, but nothing will do.
I'm running QtCreator on Windows 7 64 bits. I'll try on my laptop which is also running windows and will update if I find anything.
Any help would be appreciated, I need to start a project as soon as possible. I'm relatively new to QT and if you need info on anything just ask me. Thanks :)
Use dependency walker, http://www.dependencywalker.com/
and post any missing dependencies. It is possible some install targets or options are missing from when you installed QtCreator, which can be resolved with the maintenance tool in the same directory you installed Qt.
Also, are you using the Visual Studio compiler(must have Visual Studio installed separately, and mark the option during install), or the Ming compiler(2 options checked during install or maintenance)?
Check if your antivirus is locking it, I had a similar issue time ago and it was due to antivirus (Avast specifically). Disable antivirus' realtime shields and try to execute a basic app.
It is necessary to use QtCreator? I use QtDesigner snd VS2013 and things go very well. :)
check this thread Qt Creator Plain C++ Project won't run/debug... and this C++ - QtCreator doesn't show any output
I'm trying to build the Windows version of my app. The program compiles and runs fine on Qt Creator but when I try to run it standalone it throws the following error:
The procedure entry point _Z17qt_message_output9QtMsgTypePKc could not be located in the dynamic link library QtCore4.dll
I have all the necessary dlls in my application folder and they are the same ones that came with the binaries I've downloaded from the Qt's website. This error is driving me crazy for I can't seem to find any reason for it. The application runs fine on Linux and MAC OS X.
Ok I found the problem. I was copying the wrosng dll (not sure why Qt ships with 2 different versions).
The right ones are in:C:\Qt\2010.05\qt\bin and NOT in C:\Qt\2010.05\bin
I hope this helps anyone who might stumble upon this issue.
