Hello,
I installed VB2005 recently and today I attempted to install SQL Server Express. Installation failed saying that Existing Components Existed.
Message was: Existing Components
SQL Server DB Series
9.00.1399.06
I believe that is SQL Native Client. It could also be from SQL Books Online.
I have Add/Removed the SQL Express Components repeatedly and retried with the same results. I'm not sure if there is a Registry Entry that needs to be removed or other issue.
I sure would love some assistance in getting this resolved.
Thanks Paulz

Problem Solved.
See: http://blogs.msdn.com/astebner/archive/2005/09/13/465401.aspx
and then: http://blogs.msdn.com/astebner/archive/2005/07/01/434814.aspx
The second URL points to a utility (msiinv.exe) that displays publicly documented MSI's. The utility created an output file that gave me insight into a previously installed SQL and its Windows Installer Product Code.
Using msiexec.exe and the above product code I attempted to uninstall the product and then reinstall SQL Server Express. It failed again but in a slightly different way. I re-executed msiinv.exe then msiexec.exe with additional product codes. As it reinstalled it brought up different information but failed again.
Running the cycle of msiinv.exe and msiexec.exe again did the trick. This time SQL Express installed properly and ran.
I don't know what caused the problem(s) but the above process did the trick. I hope that this information can help anyone else who experiences the issue.

Can you look at the file %ProgramFiles%\Microsoft SQL Server\90\Log\Summary.txt and see if you can determine the problem Otherwise, copy/paste the section of the log file that contains the error, +/- 10 lines.
Thanks,

Jeffrey,
Thanks for the reply. The Summary.txt file doesn't exist. Its truncated and says setup was interrupted. Below is "SQLSetup0001_P4-3200_Core(Local).log" from the Files folder in the SQL Folder Will this help
