I most likely caused this problem for myself, but I would welcome any suggestions to help dig me out of this hole.
First of all, I tried to install texlive 2011 and got the error message that my local version was different from the version in the repository (should have read the instructions first...). In any case, my easy fix was to just wipe out my entire
C:\texlive folder. Problem solved, right? Not so much.
I then read that I should have used the Add/Remove programs option in Windows to get rid of TeX Live, which I then did. I also removed any reference to
C:\texlive from the
PATH. However, I'm still getting
the local installation and the repository being accessed are not compatible: local: 2010 repository: 2011 Perhaps you need to use a different CTAN mirror?
Where else do I need to go so that my computer doesn't still think TL 2010 is still installed?
