CC Desktop Update PS or Ai will always fail if you do not restart the machine.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

ok.

then most likely the update starts and is blocked.  you can check your activity monitor or task manager to confirm if that's the case.

I didn't notice that error; I simply saw that the update failed repeatedly.

the update fails because adobe's secure servers can't be reached?  (ie, that is the error message you see?)

Although certain situations may cause the update to fail, most of the time my internet connection is incredibly smooth and I'm not doing anything else, so using the retry button should work.

there's something on your computer (eg, av) interfering with the update.

tracking down rhe culprit is more difficult than restarting your computer, so tou might want to just restart.
