Surprise surprise, Windows 10 screwed up my game again, so I'm having to reinstall from scratch... again. Problem is, I can't uninstall Double Deluxe because it thinks Mansion & Garden is installed, even though I've cleared all traces of it, including registry entries.

For some reason, clicking uninstall on M&G (via control panel or exe) never did anything, so I had to manually remove it. I deleted everything within C:\Program Files (x86)\EA GAMES\The Sims 2 Mansion and Garden Stuff and removed all registry entries I could find (and I've looked pretty thoroughly). Is there somewhere I missed? While I could just manually delete DD I'm thinking this remnant of M&G could cause problems when reinstalling, so I'd really like to solve it.

Just deleting the files doesn't uninstall it. Go to control panel and uninstall it from there.

^ Read above. Control panel does nothing.

Found my problem, which I'll share in case it helps someone in the future. So one registry line was causing the problem. Under Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\EA GAMES\The Sims 2 there was an entry called 'EPsInstalled' and its data was ",Sims2EP2.exe,,,,,,Sims2SP4.exe,,,,,,,,,Sims2EP9.exe". Turns out EP9 is actually M&G, so I tried removing that part of it (so I was left with ",Sims2EP2.exe,,,,,,Sims2SP4.exe"). Only then it finally accepted that M&G wasn't installed.

If you tried uninstalling via control panel, you didn't mention that in your post.

They did mention it, maybe you missed it:


Glad you got it fixed, Bubblebeam!
