Here's a new one for ya.
I have 2 accounts: admin & limited. I use the limited.
Upgraded from live essentials 2011 to essentials 2012. had mesh, skydrive, photo gallery/movie maker, and outlook hotmail connector.
The upgrade updated skydrive, outlook connector, and photogallery/movie maker, and removed mesh, as to be expected.
logged into limited account to access photo gallery and got this:
Went back to admin account and repaired it. It mentioned that a file corruption was preventing the repair. So I uninstalled it, reinstalled it, restarted, logged into admin, and accessed photo gallery. Worked fine.
Went into limited account again with the same error. It does eventually start up, but you have to click OK 5 times to make the error disappear.
If someone knows a fix, let me know. I'll keep trying to work it through, and I'll post what I find.
This is the 'corrupt profile error' when I try to repair:
