Hi Everyone!

I have built one gui and built in using Qt Creator. I built both in debug and release modes.
Calibrator is Desktop Qt 5.9.6 MSVC2015 64 bit.

So Now I have executable both in debug and in release folders. When I copied only exe which i got from debug it throwed me error that some dlls are missing which is expected.
To fix this i copied this dll and it worked

Now i also copied executable which i got from release mode(Here i deleted the previous copied dll's because those dlls are specific to debug). And tried to run and it throwed me error mentioned in the question

I tried to google and went through some questions but none helped me.

Thanks for any help in Advance
