Several days ago I updated Photoshop and Camera Raw, but the update to Lightroom Classic failed. It hung repeatedly at about 40%. That led to much investigation, which led to a re-installation of Creative Cloud, which failed repeatedly around 20%. Somewhere in there I was led to the Install.log, which showed no errors. Symptoms in updating, for all instances: installation proceeds in half-percent increments, followed by pauses varying from a few seconds up to a minute, except that installation eventually holds constant for hours - when I'd shut it down. I don't have the fastest service, but it's adequate for streaming movies, and I doubt our ISP would have any knowledge of what a half-percent of any Adobe download would amount to, so this looks like something with Adobe - although I don't doubt there's also some Microsoft change involved (possibly similar to a recent Apple change that has caused similar problems there).

An Adobe tech took over my computer (with permission, of course), and reinstalled Creative Cloud. I noted that there weren't significant pauses after each half-percent of the download. After that I told Creative Cloud to uninstall Lightroom CC, then reinstall it. Reinstallation failed, hanging as before. Further searching for a solution pointed to a need to uninstall and reinstall Creative Cloud, which I did. Reinstallation hangs after maybe 20 minutes, something like 14%, remains there for hours. I cannot guarantee that I did everything just as the tech did, but I sure saw much of the same stuff go by, such as the DOS-like uninstaller. When the tech did it, there were no pauses after each half-percent of the download. But that's what I am back to, and everything I try leads to another hang-up.

Install.log is quite lengthy, now. Mostly 0 errors for a bunch of attempts, but eventually I get far enough back to find the session with the tech, and find three errors such as "Cannot load AMT config file," followed by more log from the same session where everything went okay.

So what's going on? One "help" item through Adobe seems to be recommending I uninstall all the CC apps and start over. I don't think much of that, under the circumstances. I mean, right now I can still use Lightroom Classic and Photoshop just fine, but can't seem to upload anything successfully without a tech doing it.
