Vantage 8.03 client problems on Windows 7 64 bit

Do anyone have any experience with Windows 7, 64 bit computers and Vantage? I had to order 2 new computers. Windows 7 is the only o/s available, and I inadvertently got 64 bit. At this point the computers are randomly freezing or giving us 7224 and 7175 errors.

Of course, Epicor support, is not supporting Windows 7, 64 bit on Vantage. I called and they made a few suggestions. Time will tell whether they will help.

Any help would be appreciated. I've got another computer coming in tomorrow. This one is 32 bit, but Win 7 is unavoidable.

Thanks
