This application failed to start because it could not find or load Qt platform

[Anonymous]

One week ago i installed the bonus tools 2017 for maya and when i tried to open all my 3 versions of maya (2016, 2016.5 and 2017), i get an error: 

This application failed to start because it could not find or load Qt platform plugin "windows" in "".

Reinstalling the application may fix this problem

and the software dont open after that.

I already tried to unistall/reinstall C++ redist (from 2010 to 2015) as i saw in other autodesk forum an specialist said it would solve that, but the erros keep going.

I tried suport on Qt forum but nothing too.

Im not a developer but seens it wont recognize the qt.conf or the path on it (even the path inside it its all correct).

Any tip how to deal/solve this issue?

Thx

I'm wondering if you figured out a way to fix this problem?

I have the same issue but with fusion 360

I installed the open source Qt library (from https://www.qt.io/download) on my Windows 10 pc and rebooted, and was then able to download parts from https://autodesk-fusion.partcommunity.com/3d-cad-models/sso into Fusion 360.

Hey, I had the same problem in AUTOCAD 2020 and 2019. I tried to re-install them but it didn't work. Did you fix it?
