- Can I use a single license on more than one computer / multiple concurrent machines?
You may install and use the Software for personal, non-commercial use on any Apple-branded products running Mac OS X ("Mac Computer") that you own or control.
If you are a commercial enterprise or educational institution, you may install and use the Software on a number of Apple-branded products running Mac OS X ("Mac Computer") that you own or control equal to the number of licenses purchased. Installing and using the Software on multiple Mac Computers with a single license is prohibited even if the computers are not running the Software concurrently.
You can review the End User License Agreement(s) from this page: www.vmware.com/download/eula/
So if you using it commercially you'll need to put the VMware Fusion 4 application on the USB Drive as well or purchase additional licenses.
