Our Windows demo has been tested to work on Windows 8.1 or greater. While Windows 7 is still supported, there has been no testing in that version for quite some time.
Our demo has been tested to run on OS X 10.10 or greater. It may run on earlier versions, but it has not been tested on those in quite some time.
Our demo has been tested to run on Ubuntu 11+ and CentOS 5.5+. While it should work well on other Linux variants, there has been no official testing on other variants.
