I just built a new machine and need to load an older driver for one of my 44" Designjet printers, but Win 10 will not allow either the driver for Win 7 64-bit or for Win 8 64-bit because they lack a proper digitally signed certificate. Never had this issue in Win 7.
I tried using the shift/restart technique to access the Troubleshoot/Advanced Options/Startup Settings page where option #7 is to disable the certificate verification, but it doesn't seem to work. After selecting option 7 with the F7 key there is no verification of my selection, the computer just starts its reboot. This seems a little odd. Anyway even after trying this several times I still get the verification errors when trying to load one of the drivers.
Is there any known way around this? I see a bunch of certificate functionality on the god mode screen, but I have no idea how to use any of that.
Thanks for any help.
Jim
