both windows 10 and vista idk why. and yes i ran as admin.
Have you tried running it on windows 7 perhaps?
i dont have a windows 7 vm on me man
Better download a windows 7 ISO file from the Internet Archive and see if it will work.
Do you have the file you want to edit open in another place?
(This includes it running as a process.)
If so, you’ll want to close it before trying to edit it.
