As of V11, BurnInTest running on a Single User License needs an internet connection to fuction.
The license isn't locked to any given machine: it is a floating license. You can install it on as many machines as you like so long as:
At Startup:
BurnInTest will try to connect to the PassMark License Server. If it cannot connect a message box will be displayed saying "BurnInTest failed to connect to the PassMark License Server" and all tests will stop. If BurnInTest can connect but both sessions are active the server will deactivate the older session and allow BurnInTest to function.
After Startup:
At intervals, BurnInTest will check with the license server. If a session becomes inactive, such as when BurnInTest is started on another machine with the same license key, any ongoing testing will stop, results will be shown, and the user will not be able to start a new test.
However, if required, the user can restart BurnInTest to start a new session, which will deactivate the other, older active session on a different machine.
