Hi Erik, thank you. I have posted there as well.
Gary, I can try the .iso method. I have tried new downloads from the site (not using the .iso) and even tested installs on freshly imaged machines. For whatever reason, Mechanical APDL doesn't show up unless R1 came first. And then, both r1 and r2 show as working. Its very strange behavior as its the only thing I have noticed of the installs that seems to rely on something from the other.
As far as network installs go, thank you for that info. I will see if that is useful going forward in our env. Thanks again.
