When I installed R14 on Vista, we didn't get any error messages. But when I tried to open the program is when the SmartHeap error occurred. I've sent an e-mail to James Coates (from an earlier reply) but haven't gotten anything back yet.
I wonder if the dou processor is the reason why changing how the program opens doesn't help. I mean setting it to run like windows 98, 2000 or even xp. We just spent a fair amount of money for this not to work. (frustrating)!!!!!
JImmy S.: Coates knows a lot of stuff about operating systems but I doubt if he'd be much help with Autocad. He's like a lot of other "experts"; they can get you running again if it's an "ordinary" program like Word or Excel but not many of these gurus outside the Cad community are of much help.
