It's February and I have the same problem. There are other December posts with the same problem, but I haven't seen a solution posted. I have a network install, and updater crashes on the Admin workstation as well as the other workstations. The original problem was the 1065's and 1120S's not showing up on the workstations. So I tried a clean install on the admin workstation, then I get the update crashing error. If I install just the 1040, it works fine. As soon as I add the 1065, updater crashes. And yes, I've rebooted numerous times in the process. I even tried to clean up the registry of all prior traces of ProSeries 2017, and also tried using another computer as the Admin computer. Same problem. I've been on hold with support for an hour, and have to go soon. IF I ever get a hold of somebody, I'll post an update.
