If you want to use the MA 1 Multichannel Extension license for several rooms, i.e. on different computers, you can always transfer the key and use it on one active computer at a time. To do this, select the “Retrieve Key” function to first release the key again on the server. You can then activate it on the next computer.  This would at least be a workaround for measuring all your rooms with one license.

The Multichannel Extension License can be returned from a machine, using the key icon in the upper right.
