When we try to install MS SQL Server 2008 Express edition it thinks that it is already installed.
We have removed it from Add/Remove programs, I also used the Windows Uninstall cleaner utility and it is not in there.
we tried both the web installer as well as the full offline installer.
the Web one just says that SQL is already installed, while the Offline version fails at setting up the instance saying the instance name is already in use (prior installation)
any idea on how we can clean this up so that the user can do a nice clean install?
