How do I manage licenses for PDF-XChange Viewer on a Windows Terminal Server?

I want to deploy both the free and licensed versions of PDF-XChange Viewer on a Windows Terminal Server.  How do I specify only certain users to have access to the full version? 

The PDF-XChange  serial key on a Terminal Server can be stored in LOCAL_MACHINE for all users or per user in CURRENT_USER per profile.

Choose the install method that best represents your company needs:

Licensing on Terminal Server with PDF-XChange Viewer is essentially handled by running the installation either with the serial key or without. 

Installing PDF-XChange Viewer on a Terminal Server in Licensed mode for all users:

When you install PDF-XChange Viewer if you include the serial Key in the installation then all users of your Terminal Server will have access to the full Licensed or "Pro" features of the Viewer.   You can then through Group Policy and/or NTFS permissions restrict the program only to those users you choose. 

Advantages:  All users have full access to all the features of the the software and no license keys need be installed by individual users.

Disadvantages:  Requires detailed management of user permissions.  All users who are to have full access to all the features of the the software and must have rights and permissions to access the software set explicitly.  Typically this is done through a Group Policy.  All other users must be explicitly restricted access to the software.

Please note that we do not have a concurrent user license model and all users who will be granted the right to use the applications need to have a valid PDF-XChange License. 

Installing PDF-XChange Viewer on a Terminal Server in Trial mode for all users:

When you install PDF-XChange Viewer if you do not include the serial Key in the installation then all users of your Terminal Server will only have access to the free features of the Viewer.   If these users attempt to use restricted or "Pro" features a watermark on the document will result.  Users are clearly warned before this happens and given the opportunity to cancel the operation that will add a water mark. In this scenario you might want to consider hiding the restricted "Pro" features: http://www.tracker-software.com/knowledgebase/229-How-do-I-hide-the-Pro-features-in-the-Free-Viewer

You can then pass the serial key to those users whom you want to have Pro features and when they enter that serial in the Viewer manually it will be stored in the Windows Registry under CURRENT_USER so only those users will have access to the full product.  Again it is your responsibility to ensure you have enough licenses to cover all those users.

Advantages: All users have access to only the free features of the the software and individual users can be given the key to unlock only their own profile to use the full Pro feature set.  No permissions need be set up to manage access to the software.

Disadvantages: Requites any user who is to use the full featured version of the software to manually enter a serial key..
