I have downloaded a trial version and it works fine on my Windows 2003 server. However, I am also having the same issues on a Windows 2008 R2 server. I have disabled Software protection services and it still will not run - I have even tried to 'run as administrator'.
I have also downloaded the one-click admin module and again, same issues.
Any help appreciated as we are looking at buying this very soon and this is a roadblock
thanks
