Thanks for all of your responses!
I was looking at the ERA V.6 version sorry for not stating that earlier
We don't have SBS (We have Server 2008 R2) but we do have several SQL Express DBs running right now. I'm a little hesitant to install this on there. I think I'm going to put together a machine with some newer spare parts here and install a Linux server then install the RA on that and see how it goes. I'd rather try this method first and then fall back to something else if its just not working.
Thanks for all of your replies; with them I read about the Linux install and it looks like its not that big of a deal!
Have a great day,
