I am trying to upgrade (not Fresh install) SCO Unix from 5.0.4 to 5.0.5 using the SCO Unix media kit.
After booting the machine using the supplied boot disk from the media kit, following the instructions, I entered the existing license info, the error message "Invalid serialization. Not installable" was resulted.
I believe the initital installed OS was SCO Unix - Host Edition. It was then upgraded to Enterprise edition 5.0.4.
I guess what I am asking is how to upgrade the OS to 5.0.5.
I don't have any documentation with me so please supply as much info as possible.
