By default all trial, basic & premium licenses allow you to install qbase+ on 2 computers. However, you can use it only at one computer simultaneously.

The computer will automatically be linked to the license the first time you start qbase+ on that computer.

If you're linked to a group license these numbers depend on the purchased license configuration. You can find this information under the details of your license:
