Citrix Presentation Server Cannot Contact The License Server


I have been using my Citrix absolutely fine without issue, I then decided to install the latest Roll Up (PSE450W2K3R03.MSP).

Once I installed this I was getting the following error:

Citrix Presentation Server Cannot Contact The License Server SERVERNAME

I have tried everything to get this working, but nothing will get it going again, so I have now uninstalled the Roll Up and it works fine again.

My question is why is it doing this?

I am running :

Citrix Access Essentials 2.0

"Your Citrix License Server must be at Version 11.5 to install this hotfix rollup pack."

Has that been done?

Yep, someone didn't read the Readme file before installing the update.  You need to do 2 things:

Install the Microsoft C++ Redistributable package
Upgrade your license server now at version 11.6.1

Always read the readme file for Citrix updates!
