wasm: wasm apps fail to run on windows

When I try to run a wasm app with qt creator on windows, I get this error:

No module named 'win32api'
Importing Python win32 modules failed! This most likely occurs if you do not have PyWin32 installed! Get it from https://github.com/mhammond/pywin32/releases
