I have to agree with Kevin on the last point when installing/reinstalling RSView it's Studio, enterprise, factorytalk out and the reverse back on to your machine. I have a dell lattitude C820 but I'm upgrading to a new d820 sometime next week.
Also FYI my RSView studio died after installing wonderware 9.5 today (didn't have time to troubleshoot the problem so all I can say is thank god for system restore! Dodged a bullet on that one.
