I have had GP4 for years running on a 12 year old XP box which is starting to give problems. I am looking to replace the PC with a newer box, probably with Windows 7. Two questions: As most (if not all) Win 7 PCs are 64-bit now, will this run GP4 OK? Will GP4 run with multiple players on a simple wired LAN network? Are there any tips to setting this up and running it without too many problems? Thanks sincerely, AustinF1
