Client needed to upgrade his PC to windows 7, they currently are on Sage 100 Advanced 3.71. They configured to run 3.71 under windows XP mode like 2 other users and we cannot install. We keep receiving an error at 75% of install. See screen shot attached for error. I tried copying workstation files to windows xp from server. Only thing I can think of is for them to run in MAS90 mode until they upgrade. Any suggestions? NO CD available either
