Just to let you know, the license agreement for DiskWarrior 4 is the same as the license agreement for DiskWarrior 3. Any DiskWarrior licensee may take their single copy of DiskWarrior and use it on any computer they own. The restriction is only for simultaneous use, just like just about all other software. If you choose to install DiskWarrior on multiple computers to use the hardware monitoring feature, then you need to have multiple copies of DiskWarrior, or a multi-user license.

I hope this helps clear up the confusion.

Paragraph 2 of the License Agreement starts with this text:

2. Permitted Uses and Restrictions. This License allows you to install and use the Alsoft Software on any computer owned by you for the purpose of performing its functions on any disk owned by you. This License does not allow the Alsoft Software to exist on more than one computer at a time.
