Thanks, so after running compatibility modes and selecting run as admin, I got the error stating this version couldnt be run on my window7.
Then I posted and after reading your response, went back and chose 'run as admin' and lo and behold, its installing now...so I finished writing up this post and its waiting for me...yehaaa.
Thanks again, much appreciate your patient responses

(*slinks off hoping they dont think Im tooooo much of a noob)
Cheers....
