Cannot update or reinstall Lightroom
My version of Lightroom, 6.9 on Mac (macOS 10.12 and now 10.13), wouldn't update with the built-in check for updates mechanism, saying for a long while that there were no new versions. After finding that they were, I entered a world of pain.
Trying to update told me that the application manager needed to update, but that kept crashing. Digging through various forum posts, and after seeing error U44M1P7, it seemed that uninstalling and reinstalling would be what is required. Uninstall didn't go well, with the uninstaller stalling at 83% with "1 minute to go" for at least half an hour, so I had to force-quit that. Downloading the full installer and running it, it simply crashes, with the following issue (which looks much like the AAM crash, I think):

When it crashed, it told me that the log might help, but the log file just has a link to System Requirements, which my system meets (MacBook Pro late 2013, 16 GB memory).
What is my next step in trying to get things going?
