Hi Geoff,
The error code that you're getting indicates that it can't find
something ("specified module could not be found"). Unfortunately, it's
a clue, but doesn't provide much more help (gotta love the informative
error messages). In these cases, I'd make sure that all of the
dependent DLLs are loaded and placed in a path where the COM module or
calling program can find them. For me, I usually place all of the
dependency libraries (aside from Microsoft's) in a common directory and
then add that location to the PATH environment variable.
The easiest way to make sure everything is found is to put all of the
executables and DLLs in the same directory. You can use the Dependency
Walker program (DependencyWalker.com) to see all of the dependencies to
make sure that you've grabbed them all. If that fixes the issue, then
you at least know what the problem is, and then you can place files
where it's most desired and just modify the system paths.
Hope that helps.
Chuck
