I had same problem installing from disc. the setup.exe would not run. So i opened explore disk and saw a file called "a" which is an aplication, right clicked and ran it as admin and hey presto the setup.exe started up and install began. Hope this works for you.
On another note to Vecko and Peter I got rid of my XP rig, built a win10 rig better graphics and more ram. TWOS 2.2.5 runs like a dream. Thanks to you both for help in the past, keep up the good work.
