Invalid class string error with EndNote

Running Vista Basic and Office 2007

I recently purchased this laptop for work and regularly use EndNote9. After installing Endnote and copying the necessary files into the Startup folder, I opened both programs to complete the procedure. This procedure is well detailed on the ednnote site and there are useful documents regarding Vista and Word 2007. When I went to Add-ins and clicked on Insert Citation, I get the error "Invalid Class String". After communicating at length with Thompson (EndNote publisher), they recommended I check the Registry entry to confirm a particular string entry.

The information was never written to the registry.

For whatever reason, the installer is not writing the details to the regstry and therefore the error occurs.

I am at a loss to explain why it won't write.

I have full Administrator rights on the local machine. I disable the antivirus during the install and have even disabled most of the startup programs to clear the way. Still no result

Same thing is happening to me with Vista, Word 2003, and EndNote5. Any suggestions

Sorry, this is the Windows Desktop Search forum. You may have better luck asking this question at the Windows Application Compatibility forum.

This said, I did some research and it looks like EndNote has known compatibility problems with Windows Vista. Details and workaround can be found here: http://www.endnote.com/envista.asp

Thanks much,
