Umm, what OS is the computer you are trying to run the disk on and failing? Is it Vista? If so, have you verified that the game is Vista compatible?Good question. Maybe sfc /scannow is due.
You may also try copying DVD to your hard drive, and install it from there.I think you can try making an iso file of the dvd disk and then attempting to open it with some virtual drive software like daemon tools. This may get you to install the program and then if it install okay, then try playing game with normal disk in place. Or you can play with the virtual disk you already created (unless you want multiplayer mode, which many times don't allow virtual DISKS)when the disk is placed in another computer it instal without probelm. My computer is Windows XP. I attempeted the install after copying all the files off the disk and trying the INSTALLATION is safe mode but then i get a message saying "1607: Unable to install InstallShield Scripting Runtime."Quote from: magu55555 on June 04, 2008, 01:13:06 AM
