Cant load Visual Basic 6.0 MSADDNDR.DLL

I can not load my Visual Basic 6.0 program due to an error: Failed to register C:Program Files\ Common Files\ designer \MSADDNDR.DLL

The setup does not complete. I am using Windows XP Home Edition Build 2002.

Any help would be much appreciated- adobi81638@aol.com Alan Dobinson
