License Upgrade Information: Upgrade purchases require a version 3 or 4 license to activate. You will need to enter your prior license key the first time you activate the software. After activation, the new EZ Green Screen 5 serial is upgraded to a full license. For future activations, you won't need to enter the prior serial key.
EZ Green Screen 5 will NOT affect version 3 and 4 installations or activations. Prior versions will still run and activate normally.
Each version 3 or 4 license key may be upgraded one time. A prior version two computer license can be upgrade to either a two or four computer license. Also, prior four computer license can be upgraded to either license as well. The prior license version will retain the original number of computers. For example, if you have a four computer EZ Green Screen 4 license and upgrade to a two computer EZ Green Screen 5 license then your prior EZ Green Screen 4 license will remain a four computer license.
