Notes
On Center Software tests our software in conjunction with products currently under "Mainstream Support" with Microsoft. Once a version of Windows is 'retired' by Microsoft, On Center no longer tests or supports our software on that version. See CLS - Product End of Life (Sunset Plan) for more information.
The minimum system requirements support basic functionality of On Center Software programs. Actual requirements will vary, depending on your system configuration, other applications installed and running on your computer, the complexity of the electronic plans you use, and if you use the programs interactively.

Stop of windows 7 support so early is very stupid as many enterprises are still relying on Windows 7, as the 8 and 10 are not yet Large Company friendly.
