Hi
If you are using the visual studio compiler. First step could be to find the entry in
Add Remove Programs and ask it to repair and see if that fixes anything.

@mrjj thank you for your response.. unfortunately didn't work for me..

@xenovas
Ok, then you can try start the Qt maintenance tool and use it to reinstall Qt.
Did this happen after you installed visual studio update or similar ?

@mrjj hello again, problem fixed for me.. i was using the wrong pythonpath..to fix it i have deleted the pythonpath pointed to python 2.7 Lib from my env variables and i have only kept the pythonhome variable pointing to python 3.7.2.. Thanks

For me this pops up when the application executable cannot find the required dlls for the application to run.
First click on the executable/build application in your respective debug/release folder and check what dlls it is asking for.
Find the respective dlls in your external framework files (usually in the bin/relevant architecture) and copy them in the qt application/builds local directory.

Confirmed. I'm disappointed only why this error message is so noninformative :-(

I fixed it by checking "Force UTF-8 MSVC compiler output" in "Kits" settings. I have no idea why. I think this error message is a symptom of various otherwise unrelated issues.

So I am getting this problem suddenly. I just upgraded from Qt 5.12.8 to 5.15.0 and at the same time from QTCreator 4.12.0 to 4.12.1.

The "Force UTF-8 MSVC compiler output" does not solve it for me. Somehow I think I must have an inconsistent tool chain. I am using the VS2017 compilers, maybe I should use the VS2019 versions. I can still build and run my 5.12.8 stuff. But the 5.15.0 builds don't work. (And wow, endl is deprecated, but that is another story).

If you run your executable file inside the debug folder and it asked you to give control access to the app, then you might need to run QT as administrator, this worked for me

I had the same error, it was caused by a missing DLL.
