I have Windows 10 (32 bit) loaded on a test computer and FTM V11 (2006) works on it. The only feature that doesn't work is printing to PDF which hasn't worked since Windows 7 with that version. So a 10 year old version of FTM works on Windows 10 if that means anything and I also have it running on Vista, Windows 7 64 bit and Windows 8 64 bit.
