First of all redownload MSN messenger 6.2 and try installing it on an account with "adminpriviledges" (to be sure you got the right one reboot into safemode and choose the account called "administrator"). If that doesn't work try the following:

1) Click Start > Run
2) Type msiexec /unreg and press enter and wait until it appears to have finished.
3) Go back to Start > Run
4) Type msiexec /regserver and press enter.
5) Try to install MSN Messenger 6 again.
