When deploying Acrobat Standard X for 1 user on a terminal server, everything works fine. But this terminal server is one of 4 servers in a farm.
The 3th Terminal server tells me i cand activate the licence because it's already activated on the others.
You i need to purchase 4 licenses for just 1 user?
It looks as though you have purchased a Retail single user license, thus the limit of 2 product activations, which is intended for users to be able to install their licnese on a primary computer and a potential backup or mobile (laptop) computer. Before installing an Acrobat license in a terminal server environment, you may wish to read this FAQ: http://www.adobe.com/aboutadobe/volumelicensing/pdfs/acrobat_on_a_server_policy_doc.pdf
