I have moved this discussion to our Remote Control forum. You will likely get better help there as it is the appropriate topic.
One of our other techs did the following during the scenario:
"Renamed the issftran.dll and issftran64.dll files to .old in \LANDeskSoftware90SP2\LANDesk\PF\LD\MS\_non. Then copied the issftran.dll and issftran64.dll files from \LANDeskSoftware90SP2\LANDesk\SP\Image to \LANDeskSoftware90SP2\LANDesk\PF\LD\MS\_non to replace the .old files that I renamed. Once this was done and the system rebooted, the install completed."
