One of our designers is having a problem getting this to work. I am thinking he may have a setup/install issue with one of the apps. Any information pertaining to this would be greatlty appreciated.

Error: Unable to cast COM object of type "Illustrator.ApplicationClass" to interface type "Illustrator._Application". This operation failed because the QueryInterface call on the COM component for the interface failed because no such interface supported.

I think it has to do with the installation of Illustrator. If installed properly, the COM Type Library should be available. Also make sure you using the CS2 COM Type Library. There could be problems with earlier versions as I haven't tested against those.
