Windows 10: "No Qt platform plugin"-Error when opening application

Hi there,Since a little while ago my Windows-application "Logi Options plus" doesn't work anymore, when I try to open the application it throws the following Error: see screenshotError: "logioptionsplus_agent. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: direct2d, minimal, offscreen, windows."I've tried re-installing "Logi Options plus" a few times, but that didn't resolve the Error. Also, I've installed the "Qt"-application from qt.io, latest version & "5.14.2.0"

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,

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.
