Before upgrading to icepak 18.2 was using icepak 16.2 and it was able to open two files at the same time, so I was able to give run in one and use another one for setting up another project. But now it gives license error if there is one file open already and if I try to open another icepak file.

Ansys people say that there has to be 2 licenses to open two files at a time. Doesn't make sense because I have used two files at the same time before.
