How to patch .NET dll to the GAC using InstallShield QuickPatch?

Question

I'm trying to patch a .NET DLL file using the Quick Patch project of InstallShield. The DLL needs to be registered for COM Interoperation.

When I patch the file, the dll seems to be replaced correctly in the GAC, but when I try to access it from my application I get an error indicating that the application cannot connect to the DLL.

I think that it is not being registered properly for COM interop, but I'm not sure about it.

Any idea of what should I do to make it work?

Thanks,

Have you set the ".NET COM Interop" attribute on the component to Yes? — Christopher Painter
Yes I did set the .NET COM Interop attribute to yes. During a clean installation the DLL is properly registered to the GAC and available for COM Interop. Thanks. — Juan C. Becerra

You probably have to run regasm(it's in .NET framework directory) with correct params to register for com interop. Also the DLL file is usually built with certain COM visible options selected. Been a long time since I dealt with that nightmare though, so can't remember all the details.
