Cant export movie

When i try to export my project an error message pops up saying it "cant create the specified file. “probably the parent folder does not exist or is not writable”
Ive tried multiple suggestions from the forums but none seem to work.
I have Quicktime 7.7.6 as i heard you should use an older version on windows, had the newer version before and couldnt export with that one either.

Ok so after two weeks and after having the same issue with Krita i found out it was Avast Antivirus what was stopping my animation from rendering, im not sure why it was doing it but after uninstalling it i had no problem exporting on both programs. Just adding this comment in case anyone has a similar issue in the future and finds this. Dont trust antiviruses
