P.S. No changes or editing of the PATH environment variable is needed for Qt to work.
Thats actually not always true, I for example had to add the MSVC Debugger manually for 5.9.1 in the project settings
-
@J.Hilk Yeah you're right, debuggers needs that.
-
Correction,
eventually Windows did find multiple instances of the ucrtbased.dll. They are located in the C:\Programs and C:\Programs (x86)\ folders and there deep in the Microsoft SDKs and Windows Kits folders respectively.
-
@ghost23 'ucrtbased.dll' should be there in your C:\Windows\System32 folder, it's a part of the MSVC2015 installation.
-
OK, so now that I found those DLLs, what should I do next?
-
@ghost23 Since ucrtbased.dll is in C:\WIndows\System32, which always in hardwired into the PATH env. variable, no further action should be needed.
But since it fails, try doing the exact same thing inside your Visual Studio 2015, i.e. building a simple 64-bit console app in debug mode. It should fail in the same way in Visual Studio...Edit: forgot to mention, also try disabling your anti-virus program (if you have one).
-
Hi,
well, as I said above, the ucrtbased.dll is not in my System32 folder, but in a subfolder in C:\Program Files(x86)\Windows Kits...
I also tried disabling my anti-virus program, but it didn't make a difference.
-
@ghost23 You should not add anything to PATH - it is not needed!
It should work.
You're using QtCreator? -

But for that you do not need PATH, right?
-
@jsulm Nope. you need to add the Windows(10) Kit binary folder to the Path variable
in my caseC:\Program Files (x86)\Windows Kits\10\bin\x86
-
@J.Hilk I'm not using Microsoft compiler, but can't you just add the absolute path to the debugger in QtCreator?

If I'm not mistaken, than changing /adding stuff in your path variable via Qt-Creators project settings
is exactly that. My global System PATH variable is unchanged.

Hi,
oh so many replies :)
So, yes I am using QTCreator. So, I have added the path to the x86 version of the ucrtbased.dll to the PATH variable in the System environment variables.
A little bit has changed, when doing so. When I run the .exe manually in a CMD window, now I get the error "0xc000007b".
IN QTCreator, though, I still get the same outcome, as before, although in the Project settings, I can see, that the Path to the ucrtbased.dll is also added.
-
@ghost23 Close, but no cigar. Error "0xc000007b" means that your 64-bit console program is trying to load the 32-bit version of ucrtbased.dll :-( You need to find a 64-bit flavor of ucrtbased.dll on your computer.

Hi,
ok, so this took some time. Yesterday I found, that I had installed a mess of Microsoft and Windows SDKs and I thought, let's clean this up. So I uninstalled all those SDKs. Then I read the Qt documentation again and it says, that I should install a compiler as a requirement for Qt. One of the recommendations is to use Visual C++ build tools. So I have installed the Visual C++ Build Tools 2015.
Then I start Qt, but I cannot compile my plain c++ app in Debug mode, because Qt cannot find a debugger. After some investigation, I find, that the Visual C++ build tools 2015 do not contain a debugger. Why isn't that mentioned in the documentation?
So after somer further googling I find, that the Windows SDK comes with a debugger (the cdb.exe). So I install the Windows SDK. Now I have a debugger.
Then, when I tried compile my app in debug mode, I got this error:
LINK : fatal error LNK1158: cannot run 'rc.exe'
So, for some reason, the place, where the rc.exe is, wasn't in my PATH. Added it, now finally, I can compile both the debug and the release version and run them without errors.
Man, I have to say, I haven't even written one line of code as of now, but I am already exhausted.
Thanks for all the help, though. Much appreciated.

@ghost23 jup, run into exatcly the same issue.
But the advantage of the MSVC compiler is, that it's about 5 times faster (on Windows) than mingw, so you'll have that time back in a couple of weeks :)You should set the topic to solved, if you managed to solve your problem :p
-
@ghost23 "I cannot compile my plain c++ app in Debug mode" - you don't need a debugger to build in debug mode. You only need it if you want to debug.
"Why isn't that mentioned in the documentation?" - it is: http://doc.qt.io/qtcreator/creator-debugger-engines.html
