- Windows virtualized on a MAC
- Citrix or other virtual desktops/application publishing environments
- Windows® 7, Windows 8 and 8.1, and Windows Server 2012 (unsupported operating systems)

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.
