Hi all, I'm am a recent convert to MAC and I'm very happy with it and Parallels. I'm also a full time RVer and have been using S&T for some time on a PC. Now I'm trying to install ST2007 in XP using Parallels. The build is 5160. When I put the CD in I get a "Microsoft Streets & Trips 2007 Setup" window stating that additional system components are required. The 1st one listed is ".NET Framework 1.1". When I click OK, it starts to install that and after a few seconds, it just disapears??? Then nothing happens. I know others have installed ST from reading other posts in the forum and, judging by the dates of the posts, I believe it must be the 2007 version, but I'm not sure. I have tried making a disc copy of the CD and the same thing happens when I try to install from that. If anyone can help I'd really be thankful. Thanks for reading this post. Regards, Bill Davis
