After installation the program seems to start up normally, but after completely loading, it will present a requester with a cryptic message.
"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."
Closing the requester will immediately terminate the program. Note that before closing the requester the program seems to work normal, I can insert video clips and generate an output video.
I contacted support and it gave me a series of instructions to determine the problem, involving WinAudit and MSINFO23 reports. Then came a sequence of actions involving uninstalling VS2019, uninstalling and re-installing VS2021 several times without any change in results. I finally stopped this, because I was afraid I might wear out my computer's reset switch .
I got the feeling that tech support was mindlessly following their scripts and did not address the actual problem. One question that I would have is that VS2021 seems to use the Qt framework and the problem is clearly with the setup of that framework. Perhaps there is a conflict between some software that I already use and the Qt framework.
- Is the Qt framework used in the main application or is it used only in a helper function that I could perhaps disable or uninstall?
- Perhaps I could install Qt libraries from another source and install and test those separately? I have used Qt under Linux, so I am somewhat familiar.
