Newbie Question re: Installing Sage on WHS

[jurassicjockey]

A little late to the show, I know. I was in the midst of my trial period when google bought Sage. I tried a couple of others such as mediaportal on my server, but was never happy with them. I decided to buy a license from someone who had dismantled their whs, and wasn't using it anymore. I have a Version 6 SageTV license key, and Client license key.
First I tried installing version 7 on my whs. That didn't work. So then I installed version 6 and got the service running using the SageTV license key.
I then tried to upgrade it to version 7, and have hit a roadblock. Do I take the upgrade .exe files that were posted and manually insert them into the Sage directory on WHS (tried it with no joy, but may have done something wrong), or is there another way that I have to do this.
Ps it;s the original WHS, homebuilt, NOT WHS2011
