asp.net error 80040154 calling 32-bit COM object on 64-bit Windows?

[Ken Yee]

Anyone know the right way to fix this?

A workaround is to make your customers run their 64-bit IIS in 32-bit
mode, but this seems to tick them off that they're not using the most of
their 64-bit operating system ;-)

Are you supposed to bring your .Net project up in VS.Net 2005 on a 64-bit
system and regenerate the Interop DLL?
Are you supposed to rebuild the C++ COM object in VS.Net 2005 as a 64-bit
COM object?

Our asp.net app is currently built and shipped as a 32-bit app...


thanks,
