Accidentally, after executing the "remove program" command in the
control panel/add remove programs/Tex Live 2010, I deleted the installation folder under
C:\, too, manually.
But the program is not removed entirely, since I got error messages about version conflict with existing TL 2010 installation while trying to set up TL 2011.
Installing TeX Live 2011 from: http://www.bitlib.net/mirror/ctan/systems/texlive/tlnet Platform: win32 => 'Windows' Distribution: net (downloading) Using URL: http://www.bitlib.net/mirror/ctan/systems/texlive/tlnet Directory for temporary files: C:/DOCUME~1/User/LOCALS~1/Temp Loading http://www.bitlib.net/mirror/ctan/systems/texlive/tlnet/tlpkg/texlive.tlpdb '""C:\Documents' is not recognized as an internal or external command, operable program or batch file. C:\Documents and Settings\User\Desktop\install-tl\install-tl-20110630\install-tl: The TeX Live versions of the local in stallation and the repository being accessed are not compatible: local: 2011 repository: 2010 Perhaps you need to use a different CTAN mirror? Press any key to continue . . .
So, I don't know how to manually remove my TL 2010 installation. Anyone literate about references and tutorials which files are to be removed, where they are located, which registry keys to delete and what else to do to remove TL 2010 completely?
