GP fault and access violation is a windws permissions issue that surfcam refuses to address in installation...
1- Set surfcam to run as administraor
2- Dont install into programfiles(x86), c:/surfcam is best
3- Go into security tab for c:/surfcam and grant full control to all users
4- Go to security tab for c:/users/public/surfcam and grant full control to all users
Good luck
