Installing JRE 1.6.0_05 or later on Windows Server 2008 x64

November 7, 2008

One of the prerequisites for installing Citrix XenApp 5.0 on Windows Server 2008 x64 is to install the JRE 1.6.0 Update 5 or later. I downloaded and installed the x64 version of the JRE 1.6.0 Update 7 from as directed by the Citrix XenApp 5.0 pop-up message. However, the Citrix XennApp 5.0 installer insisted the correct JRE was not installed. I uninstalled the x64 version of the JRE and installed the 32-bit version. This resolved the issue and Citrix XenApp installed properly.

Windows Activation and Change Product Keys do not work on Windows Server 2008

November 7, 2008
I recently had an issue with the Activate Windows now and Change product key links in the System UI on Windows Server 2008 did not work. After some searching, I found the following Microsoft KB article:;EN-US;929826.
This article describes how to use slmgr -ipk from the cmd prompt to change the product ID. Once this is done, run slui from the cmd prompt to launch the user interface for Windows Activation.
