I am licensing our Adobe CS6 Master Collection via the following command in the startup.bat:
adobe_prtk.exe --tool=Serialize --leid=MasterCollection-CS6-Win-GM --serial=XXXX-XXXX-XXXX-XXXX-XXXX-XXXX --adobeid=XXX@XXX.XXX
What you need to do before you install is create a distributuion package for CS6. It sounds a bit weird as you are using Appvolumes to distribute but if you use this tool it will burn the license key into the package and there is no need to activate it after that.
Using the simple installer without creating the package won;t work, not even with a writable volume. It seems as if Adobe creates a hash file for activation and uses the computer name in it. Because you alsways get a different machine with pooled desktops and Appvolumes. The second time you log in activation is down the drain.
