Depends on the version of FTM that you have?
Also depends on which version of Windows 8 and on what type of a machine.
The Surface Tablets that are running the RT version of Windows 8, FTM can NOT be installed. But a PC with "Real" Windows 8, yes, FTM 2010, 2011 and 2012 can be installed.
Be very carful as most of these machines come with the 64 bit version and a lot of the older programs, and hardware can not be used on them.
