EGCOMLIB_1034.dll can't kill error on boot

For whatever reason I can't get rid of the following error when windows boots to the desktop: "EGCOMLIB_1034.dll" -I searched the registry and deleted values I thought were associated -but still no luck. -I had previously assumed that this .dll error was due to unnstalling an nVidia card -but I'm not sure anymore.
So I've deleted the registry values -but that has fixed nothing any ideas?
I''ve posted about this once before but thought I'd try again now that I've tried what I thought would be the cure-all.
Any fixes or ideas?
Thanks,
