What to do? You have two choices.

One is to upgrade your system so that it runs a 64bit version of Windows 7 or later. The other is to take advantage of the 30 day eval period. You may have to contact MakeMusic sales or your reseller for a refund.

The system requirements are also listed on the product comparison site. True, it should say that only the 64 bit versions of the Win OS listed work—not an issue on the Mac side since those three OS are 64bit and cannot run on incompatible hardware.
