I too am having a problem running the latest PROset/Wireless connection utility. I have a Dell Latitude D620 with the latest BIOS and the latest Chipset driver. I installed this version 126.96.36.199 and get a windows failure notice as the software is finishing. It calls it a Zero Config SVC failure. If I click on the tray icon, I get another failure notice that say it is a Framework failure and then it shuts down. Everything worked before upgrading this and I am able to access the wireless card through the windows wireless utility with no difficulty. This leads me to believe it is a Intel software problem.
I am able to open the WIFI connection Utility only by opening it through its file location. It did not identify any problems with the card, but I can not open it through the normal means
I am running XPPro SP3.
