Windows 8 with UK Language fails to install RSAT

I came across a strange issue recently when attempting to install the Remote Server Admin Tools (RSAT) on a fully patched Windows 8 VM (The issue was encountered on VM but I assume I would have the same issue with a physical desktop / laptop).  I download the x64 version from Microsoft and proceeded to install.  After accepting the license agreement the installation started and then completed straight away:

Now I knew the tools were not already installed so I attempted to install the x86 version and encountered the usual message advising that I should use the x64 (Which is what I expected).  After searching many TechNet forums I came across a few posts that advised that the tools will not install unless you have the English (United States) language pack installed.  I though this couldn’t be correct and set about testing just in case.  To install the English (United States) language pack open the Control Panel and select Add a Language:



Browse to English and double click.  From there select the English (United States)



You should now see both English (United Kingdom) and English (United States).



Click on the English (United States) and select the option to Download and install language pack (accept any prompts along the way):



Once the language pack has downloaded and installed simply start the RSAT installation again and it should install correctly this time:



Once finished you can install the required RSAT tool via Programs and Features.
