I am trying to install SQL 2005. As far as I know I have completely uninstalled all previous versions of SQL Server. I am able to install all components except the "Workstation Components, Books Online, and Development Tools". The install gets almost to the end then I get an error message, "There is a problem with the Windows Installer Package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." When I check the summay.txt, the error number listed is 1603.
I am installing from the hard drive; C:\SQLServer2005. I have both the Servers and Tools folders with all the files.
