Your Spector 360 installation allows for a certain number of Client licenses. You cannot install more Clients than the number of licenses you have purchased. However, you may purchase additional Client licenses at any time. Have your serial number ready. Look for your serial number in the Help>About screen in the Control Center. You can also find it in your original email purchase receipt or on the back of the CD holder (if a CD was purchased). If you have misplaced your product serial number, contact us.
To add Client licenses:
Contact SpectorSoft and purchase the additional licenses. SpectorSoft will make the appropriate changes to your license agreement and will update your serial number to include the additional licenses.
