I thought maybe I didn't need the update so, I tried to run the G.E.C.K. I got a different error message, "Application failed to start because libvorbisfile.dll could not be found."
Here is the data you may need in order to further investigate my problem:
Game Type: Game of the Year Edition
How I got it: Downloaded from Impulse(GameStop)
Platform: PC (Microsoft Windows XP)
Fallout Update to version 1.7: No
Please, If anyone can help I would appreciate it. I am more than willing to give out more information on the problem if needed. Thank You.
