Plan B: use an older version of Windows in a Virtual Machine (aka inside a windows on Vista). Can be any other Windows OS (so long as it's not 64-bit). For max compatibility, go for a hybrid 16/32-bit version of Windows like Windows 98 or 95.
Microsoft Virtual PC 2007 SP1:

(in your case get the 64-bit setup)
