Retroarch: Retroarch not opening: couldn't find or load Qt platform plugin "Windows in ""

[altiereslima]

I tried launching the Retroarch in Windown 10 and got the following error:

"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."

Same. Error after last Redist and .exe update. Delet .cfg stills cause it to crash.

Delete all the old .dll files before updating. I had the same problem but I think I fixed it by deleting any stale .dll files that weren't being overwritten when I extract redist within my install directory.

Edit: Actually, I'm not sure what fixed it. I downloaded the large portable 7zip file and installed all the new files after deleting my existing .dll's.

Don't worked for me... Sad.
Edit: Nevermind, it worked.
