The version is free for users who purchased or upgraded to Gamestudio Extra, Commercial, or Pro since February 2007. You can install the prerelease just like the A6 trial version, and unlock it with your key.
Please note: This is _not yet_ the official Conitec A7 release. It's like version 6.50, but with the A7 ABT engine and the new lite-C language. You can compile and publish lite-C programs with it. It's compatible to A6.50, so you can use it for your current projects - at least in theory. Try it at your own risk. Have fun!
