As far as "getting picky". During the installation, regarding the suggestion pertaining to having the latest DirectX (in this case 9.0c or greater) installed, the link below that statement brings one to a Microsoft home page that requires navigation to the DirectX page from there. Why not send folks directly to:
http://www.microsoft.com/downloads/B...n&categoryid=2 ?
I believe that's a valuable suggestion, and it applies also to the FAQ on the SereneScreen site, and elsewhere.
The bottom line would be that, the easier you make it for "joe user" to find out if he/she has the right prerequisites, and THEN the easier you make it for him/her to find and install the latest version, the fewer support problems you will have.
There are lots of alternatives for "where to send them".
