Runtime error for QT application? - windows

I have developed an application on Qt5.1 for windows 7 and now I want to distribute it. Since I have used the MINGW compiler I cannot build it static. I used dependency walker to find out all the dlls and packaged it. When I run the application on a machine which doesnot have QT development environment installed the application crashes with Microsoft Visual C++ Runtime Library error.
Could anybody please point me out the problem?

The error was
Fixed the problem:
The fix is add a folder platform into the location of your application executable and into that copy qwindows.dll from the loaction 5.1.0-rc2\mingw48_32\plugins\platforms of your QT installation.
Also all the dlls need to be copied!

It seems like you have missed some DLLs. Try again with dependency walker, I have faced the same issue once. The dependency walker did not show missing DLLs but some were missing. Try to search in SO, there are similar questions.
Do I have to include all these Qt dlls with my application?

issues with WS2_32.dll behavior between windows 10 vs windows7

Did not find any suitable solution with existing questions so asking new question here.
We use log4cxx which has WS2_32.LIB as dependency. WS2_32.LIB is present in Windows SDK version 10.0.16299.0.
When using this log4cxx.dll on windows7 WS2_32.dll and all its dependencies gets loaded properly and application start normally.
but in windows 10 environment WS2_32.dll expects dependent dll's like API-MS-WIN-CORE-CRT-L1-1-0.DLL which are not part of windows10 or any of the microsoft visual c++ Redistributable which results in application error.
difference in WS2_32.dll and its dependencies between Windows7 and windows10 are clearly visible via dependency walker.
WS2_32.dll on windows 10:
whereas
WS2_32.dll on windows7 is
as shown here API-MS-WIN-CORE-CRT-L1-1-0.DLL is not a dependent dll in windows7 where as its in windows 10 which is not present in the system resulting in application error.
So what should be the way to make the application run successfully? what alternate dependency should be provided instead of WS2_32.LIB while compiling log4cxx.dll to avoid this issue in windows 10? Also where to find documentation about such changes between windows OS versions?
Please suggest.
The old depends.exe doesn't support those API sets and shows wrong data.
use the open source replacement called Dependencies:
Dependencies is a rewrite of the legacy software Dependency Walker
which was shipped along Windows SDKs, but whose developement stopped
around 2006. Dependencies can help Windows developers troubleshooting
their dll load dependencies issues.

api-ms-win-core-libraryloader_l1-2-0.dll on windows vista

I have not enough knowledge on how to fix this. What I do know is:
Build a Executable in Visual Studio 2010 on Windows 8.1 (hence the 1-2-0.dll)
Running the executable, crashes on Windows Vista with the message: "This application could not be started, because of the api-ms-win-core-libraryloader-l1-2-0.dll"
Under vista you would have the libraryloader 1-1-0 if not mistaken?
this library is linked from mscorlib.dll somehow? But not referencing this dll would not build the project.
Maybe someone could direct me in correct way? Or better have a solution for this?
Is there a way to tell VS to not use this latest dll version?
I am certain I did not reference this specific DLL.
I got the same problem, in my case I was providing the d3d9.dll and d3d11.dll, that I copied from windows 8.1 windows instalation directory and ofc. I cant use those!
And then all Computers like Vista, Windows 7 and even Windows 8 had that Error:
"This application could not be started, because of the api-ms-win-core-libraryloader-l1-2-0.dll"
Because this file:
api-ms-win-core-libraryloader-l1-2-0.dll belongs to Windows 8.1
Solution?
In my instaler, Installshield, I removed the d3d9.dll and d3d11.dll, so my aplication will use the ones already in OS.
The problem was not in the "EXE" produced by Visual Studio, but in DLL dependecies that I was providing.
this problem occurred due to Compatibility with older operating systems.

I have the mingw48_32 version, and 32 bit version of Qt 5.2.0.
I dont have Visual Studio, although I did download and install some of the
2010 VS SDK and .Net framework stuff, still no luck.
Ive tried searching for these things to no avail. If it is somewhere on my machine
I have yet to find them.
After running dependency walker it shows the following missing DLL's:

I really appreciate any help on getting past this! Already spent a couple days
trying to figure it out.
Thanks!
The same thing happened to me today. I found the problem. My program was loading a DLL with wrong version. This can occur when from the PATH or in the folder of the program is found incompatible library, which have references to these "missing" libraries. In the documentation of Windows is explained in what priority folders are searched for DLLs.
I had the same problem. I realized that I have been copy the wrong dll files. They had the same name that the old version (qt 5.0 to qt 5.5.1). So, I just copy the right files and was done.
If qt project depends on multimedia plugin:
in .pro file add
win32: QTPLUGIN.audio=qtaudio_windows
I get similar errors when I compile a C++ program under Windows 10 with Microsoft Visual Studio 2010 and try to install it under Windows 7. The solution: compile the C++ program under Windows 7.

The application was unable to start correctly (0xc000007b)

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.

Native x64 dll does not work

I have an application that I compile as x86 code but as a separate version, as x64 code as well. The application basically has two parts, a c# managed exe and a c++ unmanaged dll. I have problems with the latter. On my development PC (Windows 7 64-bit, Visual Studio 2008) I create a setup with a deployment project and this setup installs the application in Program Files... as it should and the application runs. I also have a test PC (Windows 7 64-bit with practically nothing else). There the application still installs into Program Files... but it does not run, I get the BadImageFormatException when a function (any function) of the unmanaged dll is called. The problem is that my own project that produces the dll also makes use of quite a few freely available libraries (e.g. glew32, openal, freeimage, etc.) I took as much care is possible to make sure that I use the x64 versions of these libraries, but something still must be wrong. For some reason one of the libraries used by my dll is not available as x64 code on the test PC but it is on the development PC. At least that is the only explanation I have at the moment why my setup works on the development PC but not on the test PC.
My question is: how can I find out where the problem is. The error message I receive does not tell any helpful detail. I tried to analyze my dll with depends but it looks OK. It lists a lot of dependent libraries as X86 (these are probably system files) but all those that I use on purpose are listed as x64.
Is there any way to test why the Windows on my test PC tries to run the DLL as x86 code even though it should be x64?
Thanks.
I noticed something very strange: My application is being deployed in the Program Files folder as it should be for a x64 application but it fails to run. However if I copy all the files in the folder it is installed to to another folder (inside the Documents folder) the application runs perfectly.
Run Fusion Log Viewer in the machine where you want to diagnose the issue. Look carefully at the logs and you'll see exactly which dlls are being loaded, and where from.
You have build your .NET executable (or DLL) with Any CPU configuration, and you have given x64/Win32 native DLL for Win32/x64 (i.e. wrong config).
On x64 systems, your .NET binary will try to load the native DLL as if native DLL is x64.
And on 32-bit systems, it will try to load 32-bit native DLL.
I found the answer. The problem was not the 64-bit dll at all. One of the libraries I did not make but I link to (I do not know which yet, there) seems to try to write a file to the application folder. Of course, this is not allowed inside the Program Files folder unless you run the application as an administrator. Sorry for asking help for the wrong question.
