I’m successfully going through proccess of building an application in Qt but when I try to run .exe file by double clicking on it (outside of qt) I’m getting an error saying:
“The program can’t start because mingwm10.dll is missing from your computer. Try reinstalling the program to fix this problem.”
I checked for this file and I found it, so I think there is some path to be set in qt, but I don’t know neither where and how to do it. Could anyone explain to me how to do it?
Thank you.

    I think you need to add the directory containing mingwm10.dll to your PATH environment variable. I am surprised this was not configured correctly when you installed Qt/MinGW.

    Control Panel -> System -> Advanced -> Environment Variables -> PATH
