Is there a tool to remove all versions of Crystal ?

I'm still finding Crystal DLL's in the GAC after uninstalling all versions of

"Crystal Reports" or "SAP Crystal Reports" found in "Programs and Features"

of "Control Panel".

My goal is to work with 64-bit Crystal in development environment for deployment

to 64-bit server but I'm finding non-64-bit DLL's still present in development machine

GAC.

There are no "Crystal - Uninstall" menu items in Start menu.

Thank you,

Pete J.
