Microsoft Visual Basic: "Automation Type Not Supported in VB" Error

I am looking for general reasons I might receive the "Automation Type Not
Supported in VB" Error. I only receive the error on one machine out of 25.
I believe it is a DLL incompatibility, but am open to all ideas.
Thanks for the Help
Brian

Brian,

Can you track the error down to a specific line of code? or does it happen
when starting the app?

I believe you're right. The "usual suspects" are oleaut32, olepro32, and
comcat. These must be a compatible set, and should not be earlier than the
ones on the machine you compiled on. (well, except that the 4.71 comcat
continues to be the most general and generally "safest" version, because all
later versions are smaller, with less functionality. I've never caused a
problem replacing a later version with that one...).

I have not had a chance to do that. But will be going to the offsite location
tommorrow and Thursday. Will try to determine specific line.

Thanks for your help!
