Do I need to force the GAC to reload an assembly? Is this possible?

gac

I've added types to my .NET classes that I'm using for COM interop. To get it to work with my VB6 application, I unregistered the DLL and re-registered it (using regasm). I then uninstalled and reinstalled it to the GAC (using gacutil).

The types are showing up in the VB6 object explorer, but when I run the application in the VB6 IDE, it breaks on the line that instantiates the new types with the error: Automation Errror - The System cannot find the file specified.

I thought this odd since I had already updated the GAC, so I uninstalled the dll from the GAC and got the exact same error, which seems to indicate that the older version of the dll is already in memory and needs to be "reloaded" so that the newer DLL is in memory. Is this possible, and if so, what do I need to do?
