Another way to run old software is to run 32 bit Windows in a virtual machine under some other OS such as 64 bit Windows. The easiest combination is to use Windows Virtual PC and Windows XP Mode on Windows 7 Professional (or Enterprise or Ultimate); you don't need any additional licenses to do that.
Other combinations are possible but require an additional software license. You could run 32 bit Windows under Windows Virtual PC on Windows 7, under Hyper-V on Windows 8, or under various virtualization programs on Linux. |
