run regasm.exe on a .net com class

Question

how to run regasm on a .net com visible class from installshield? I can manually register by calling the regasm.exe on the dll but when i set the '.net Com Interop' to 'Yes' in the installshield project i get an error -6210.

Answer 1

This was happening because the version of the .net used to build the DLL was latest than the one specified under Tools>Options>/ .net tab. When I updated the .net folder to the latest one there, the error went away.

Answer 2

Sounds like there's a problem finding a dependency of the COM DLL.

Answer 3

You usually want to avoid running regasm during installation. If InstallShield doesn't know about the modifications to the system, it can't guarantee that it will clean up properly. If you can't get IS to extract the information from the links in the other answer, you might use the /regfile option of regasm to get the keys and add them to IS.
