Didn't see your post the first time around.
It is a property setting for COM.
So if you're using Visual Basic, you need to use that line.
For other languages, you'll need to look at your 'calling COM' documentation.
For MFC I think I read somewhere that it was hard-coded but I'm not sure.
It isn't something I've need to change - I've only seen the error in one circumstance, when running batch jobs in the background and test/developing in the foreground.
A faster PC would help as well!
