Same problem here
Vista 64 bit, SH III DVD installation went fine. Update to 1.4b went fine too.
Tried the starforce update but no starforce drivers. Started to start the sim but received the not supported OS message.
Installed GTL which is also a starforce sim and was able to update the starforce drivers and GTL is running.
SH III still give the not supported OS message.
According to Medico (
