Also, any chance of using the TypeLibGuid or ProgID


The TypeLib parameter is the least recommended way to specify the type library because this requires a file name whose path might differ from computer to computer.
If you are distributing your .dll, consider using TypeLibGUID or ProgID instead.

>>Thanks but it's a no-go. :( In both cases, we have to compile a 32 bit version (with the path there) and a 64 bit version (with the x86 path there) for this to work. don't want two separate exes... and if the path doesn't exist at build time (which it won't on a build server), then it won't work for either :(
