RE: UseDLL issues with a DLL in COM?

UseDLL does not seem to work correctly in my Basic MSI install.

I am trying to call a unmanaged C DLL that is in COM which is located on the PC I am installing to (from a different install). Will UseDLL still work? Will I have to change BACK to the install directory (where I am running setup.exe from) after UseDLL is successful?

I have several CA for methods contained in this DLL which are to be executed before files are actually installed. Is there something specific about the sequencing as well?

When I run the install, it looks like the method gets called but the install aborts unexpectedly.

Thank you for your time.

Since the DLL I am trying to access (methods) from is in COM, should I use CoCreateObject instead of UseDLL? Thanks.
