Hi!
I get the following errors in my translation queue.
What can I do?
Win7 x64.

-W3 -wd4396 -wd4100 -wd4996

No idea what all these parameters are.
Check the pro file and remove these parameters if they are set there.

Thank you for your help my friend!

These look like Intel compiler options. -W3 enables remarks besides warnings and errors. -wdNNNN disables a specific warning number. So, it depends on the compiler if these make sense.

Not only Intel, but also Visual Studio : https://docs.microsoft.com/en-us/cpp/build/reference/compiler-option-warning-level?view=msvc-170

@laci7722 , if you cannot find them in your .pro / .pri files , you can use 'qmake -d' to generate a (rather verbose) trace of where qmake pulls it's options from.
