Activation of Acrobat XI after trial version deployment

Hello,

now we received our first Acrobat XI License (we don´t have volume licenses).

I built a software package and did some changes to the settings with the customization wizard (without license key).

After my first test runs I encounterd a little problem.

Before Acrobat opens in trial mode, you have to login with an Adobe ID and I´m not able to enter a license key.

Is it possible to bypass the ID login so I can enter a license key after the installation?

Thank you,

Christopher
