I think you need to start out with SecurePath 4 in order to upgrade to any version of 4. I could be mistaken as it has been a long time since I have needed SP on a Windows box.
It is best to leave the fibre disconnected during the Driver and SP installation and plug them in during the reboot afterwards.
