PRB: Error Message "Cannot insert object" in Excel

I have an ActiveX control that I developed with ATL that I recently
enhanced. I updated the type library version from 1.6 to 1.7.

The new control works fine with Visual Basic and Internet Explorer.
However when I try to load it into Excel I get the message "Cannot insert
object".

I assumed the problem was a mismatch between the version of the type
library and a version specified in the header for the control. However
synchronizing them did not help.

Someone on the vc.atl board suggested that Excel might be caching the old
type library. How can I check this? Does anyone have any other ideas what
might be causing this problem?
