Took a while but I found the following to get new hasp key drivers. I had to go into Registry Edit and turn UAC off (note many online articles as how to do this and turn it on and off). After the install of Chief Architect 10.0, the program could not find the HASP key. Yes Chief Architect Version 10/10.08 still works and I am too cheap and hardly use it enough to justify any upgrade. After installing version 10.0 from my saved installation files, Windows 10 would not allow me to open the Chief Architect program as the User Account Control (UAC) security stopped the program from opening. Had a hard drive crash and had to reinstall Chief Ver 10.0 in a fresh install of Windows 10, latest version 1004 with all current updates through November 2020. This is an old thread but maybe this will help someone.
