Installing JRE 1.6.0_05 or later on Windows Server 2008 x64

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 http://www.sun.com 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

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: http://support.microsoft.com/default.aspx?scid=kb;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.
