Window will pop open but goes away. Event log shows Faulting application Setup.exe, version 126.96.36.199, faulting module Setup.exe, version 188.8.131.52, fault address 0x001159df. I googled around I found this http://www.blackberryforums.com/bes...-4-1-express-setup-exe-application-error.html similar situation you can click it as many times as you want but setup just won't run. Ive tried 4.1.5 and 4.1.6 both do the same thing. Clues??
