Remove BIDS 2008

I have successfully installed BIDS 2008 on my machine. I removed it and now it needs to be reinstalled.

Business Intelligence Development Studio has a gray checkbox on the Feature Selection screen when you go to Customize. Visual Studio 2008 is not installed on my machine. I don't see any references to BIDS 2008 in the add / remove programs. However, the installer seems to be thinking about it.

Does anyone know how I can COMPLETELY uninstall BIDS in order to reinstall it? Is this a registry file somewhere? Any help is appreciated.
