Hi, I was trying to get a program to work with .Net Framework earlier, and in the process of doing this I stupidly deleted a file in my Registry that was essential for one of the games I run on wine to run, is there any sort of way for me to restore it?
Not without backups or knowing what registry files the game installer wrote.
You can always nuke and start over. Just find your game saves, copy them to somewhere safe, delete the prefix folder you had the game installed to, re-make the prefix, install the game to the recreated prefix, and copy in your game saves. Cheers, Jake
