Technical issues with Heroes III.

Guys, help me out, it's a complete mess! My Heroes games are in the same folder, both WoG and SoD. At first, everything was fine, but after about a month, when I launch the game, I get the message "Files from Heroes 3 are missing, please reinstall Heroes 3." I have no idea what to do! Should I really reinstall it? Or can it be fixed?

Don't waste your time with nonsense – install a good antivirus, run a disk check (and scandisk too), then reinstall SoD, copy it to another folder, for example, C\Games\Heroes3SoD\, and rename the folder where SoD is installed to Heroes3WoG and put it in the C\Games folder, and then feel free to install WoG there.

P.S. – I advise you to do the same with The Eastern Era.
