I have removed the program which the CAD software company says contains the HASP drivers.
I have uninstalled the drivers from the 'Device Manager', 'Non plug and play driver'
I also ran the manual removal for HASP drivers, 'C:\haspdinst.exe -kp -r -fr -v -purge'
and just to be 100% sure, I erased any "aks*.*" files, "hardlock.sys" and "haspnt.sys" from "c:\windows\system32\drivers"
I rebooted the PC.
I then did option ' 2. Reset Windows Update Components' from the 'Reset Windows Update Tool' - ResetWUEng'.
I rebooted again.
I then did a search for updates and attempted to install the two updates available.
Which gave the following:
