Hi all, I recently upgraded the in-laws machine and installed it with Windows 2000 (they use the machine for an Internet based business). My mother-in-law plays only one game: Slingo from Hasbro Interactive. When I try to run this through W2K, however, I receive an application error from setup.exe. Is anyone familar with this game and been successful in getting it to run? My mother-in-law doesn't understand why it doesn't work if I W2K is "better" than W98. Thanks for any help.
