Anyhow, it sounds like you need the registry cleaned and repaired.
From the overall description, their must be a number of registry keys that point to the wrong program name.
I recommend either V-Com Fix-It, or Norton Win Doctor.
There are free-ware alternatives. But I have not tried them to verify which ones are worth using.
If you are running Windows 98 or XP, you may want to try running System File Checker after the registry is repaired.
