Possibilities:
* Description on Internet states a license is required. Do you have a license? Is yours a trial edition?
* Empro is associated with brands Keysight and Pathwave. Does Empro need to be used with additional software packages from Keysight and Pathwave?
* Frequent advice from help lines: "Re-install the software." Next time you run the installer, make it easy by letting it choose its default locations to put everything... executables, DLL's, etc. Avoid trying to install on external disks.
