License issues installing Adobe Acrobat DC on Citrix VDI environment

Hi all,

I have a client who has installed Adobe Acrobat Standard and Pro DC on a Citrix (with VDI) environment.  They have multiple front end VDI servers and they have an issue with the license activations. A users can use Adobe Acrobat from any of the multiple front end servers (they are load balanced).  However, if they have already activated Adobe Acrobat on 2 of the servers, when they next activate Adobe Acrobat they may be load balanced to a 3rd server and Adobe Acrobat will not allow the 3rd activation.  They admins then have to get into the licensing and remove the initial 2 activations before they can run Adobe Acrobat again.  They are using serialized licensing.

A case has been logged with Adobe support but they solution they provided (ie using serialized license) does not appear to work.

Has anyone encountered this issue before and if so how did you manage to resolve it?
