Update Visual Studio 2026 stuck at 99% for 5 hours

I was running VS26 Community and got a popup that said it would install an update to 18.8.0, so I said postpone. I decided to do it and went to help and check for updates. I clicked on update now and it started. About 1 hour later it was at 99% and said it was finishing. I left it alone and checked back after 2 hours, and still at 99%. After 5 hours, I ended the task (Win11) and tried to open VS26, and it says the update is still running. I rebooted and VS26 says update is still running after the reboot. I went to Control Panel and I am now repairing the install, and it is at 500 out of 871. I use VS26 with the Fortran compiler, but I barely know how to build a solution since I'm an engineer and not much of a Fortran programmer.

Does the installer for the update require Admin privileges? I have to call our Help Desk to get them to supply the Admin Password, so I think that could be the problem, but it normally asks for the Admin Password early in the update.

After all this install mess, I likely will not install updates until forced. :)
