Adobe Acrobat' Problems In VPS

I installed Adobe Acrobat 7, then needed to start activation process, but the process asked me to restart my computer and close all other application before trying to activate again.

I've tried to stop VPS and Start VPS in my VPS Powerpanel, but the problems was the same as asking me to restart my computer before making the activation.

I also send a ticket to JaguarPC support, the answser was as follows,

"""Since Adobe Acrobat 7 is third party application we do not provide support for it. You need to check with the vendor or consult its documentation in order to fix the issue. """
