We recently upgraded one of our desktop applications from 9.3 to 10, we are having some trouble when trying to create a new GxFilterShapefiles(); We are getting
{"Retrieving the COM class factory for component with CLSID {90E9D96D-E647-11D3-A682-0008C7D3AE8D} failed due to the following error: 80040111."

i have read through

which has very good information on doing the upgrade, we added the needed references and the

also when trying to set display name field on an ifeature layer we get a similar COM exception.

when searching it seems that the 80040111 error code can be caused by a number of things and so far i have not had any luck troubleshooting it myself.

Any ideas would be greatly appreciated.
