I installed 1.22.2.5994 beta on a couple of PC's when it was released about a week ago. I installed it first my office PC first without any problem. I run it first in demo mode before actually using it with a trainer. A day later I tried to install it on my bike trainer PC using a network connection to the installer that was located on my office PC. It would not install. I kept getting an install error. However, after I copied the installer package to the bike trainer PC, it installed fine. I cannot recall if I had this problem before.
