Reporting Services install error 2755

I installed the eval version fine. I uninstalled the eval
version and rebooted the server. I then tried to install
the MSDN Library version I just downloaded and I get error
2755.
Any suggestions '
I tried posting this question on the MSDN Reporting
services newgroup but the site kept giving me errors
during posting.hello. i got this error message when trying to install reporting
services from a cd that was mapped via a network drive [cd was not in
the local server's cd drive]. when i ran the setup from the local cd
drive on the install server, the error was gone.
