Windows 10: This application failed to start because no Qt platform plugin could be initialised....

Recently did a system restore to a fresh windows 11 pro install due to numerous issues with an updated from windows 10 install, drivers, old programs etc.Everything was OK and then I got the subject as an error message in a window with OneDrive in the window. My start menu reset, and whenever I change it it resets again on restart. I tried reinstalling OneDrive, it didn't fix anything.I can't open mail or Armoury Crate. There were no updates that I am aware of and everything was working yesterday.

QT platform plugin missing

Hello,

I probably (accidently) deleted my QT platform plugin now I get this warning when widows starts:

"This application failed to start because it could not find or load the QT platform plugin "windows" in**,

Reinstalling the application may fix this problem."

How do I reinstall the application?

Thanks,

Lucasio

 

Could not find or load the Qt platform plugin "windows"

Windows 10 Pro

I recently installed trial version of Corel's Video Studio and decided I liked it, so I made the purchase. Now, I'm getting this error message whenever I start it:

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

Available platform plugins are: windows
Reinstalling the application may fix this problem.





I tried reinstalling the product, but that didn't help.

Searching the internet I found several posts were people using Qt indicated that they fixed this problem by replacing missing DLLs (specifically libEGL.dll, libEGLd.dll and qwindows.dll). Are these Windows DLLs or Qt DLLs? Unless Video Studio installed Qt on my system, I have no idea why Qt would be on my system, and I'm reluctant to pull DLLs off the internet for fear of viruses.

Anyone have a suggestion about how to tackle this problem?

Thanks.
