As soon as I open WMP 11 I get "WMP encountered an error and needed to close. Sorry for your inconvenience." When I try to install music match 8, the files extract. But, when it goes to install them; I get "failed to launch setup. the remote procedure call failed." I think I may have deleted a needed file with an aggressive registry cleaner; although, I dont get any dll errors.Any Ideas? I have tried reinstalling SP3, but still have the same problem. I am running win XP home SP3. Other programs in stall fine.
