There are two versions of Windows 10, 32 bit and 64 bit. My husband suggests that if you have the 64 bit version of Windows 10 it is possible that FTM 2009 is 16 bit which would be totally incompatible. Even a 32 bit version of FTM may be incompatible with 64 bit Windows 10.
Check out the compatibility mode in Windows 10, it may help.
(I am running Windows 7, 64 bit, and can't use my old Grafix software which was 16 bit, most 32 bit programs will run on a 64 bit system but some are incompatible)
Hope this helps
