Adobe update stuck

hopefully, you restarted your computer before you did anything else.  if not, for others, restart your computer before you start uninstalling and reinstalling.

at this point it's not clear what kind of mess (or non-mess) you have.  so start at the top and work your way down (meticulously), if necessary.  don't rush this process.  your next steps if all this fails, could be very time-consuming.

reset the cc desktop app: make sure it's in the foreground, then press:

Win: Ctrl + Alt + R
Mac: Cmd + Opt + R

if that fails, try to repair

if that fails go ahead and uninstall using the correct uninstaller from https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-messaging and then reinstall

if that fails, do a clean cc install following each applicable step:

uninstall every cc app including preferences, https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html

then uninstall the cc desktop app, again using the correct uninstaller, https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-messaging

clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html

update your ms visual c++, if it can be updated

restart your computer (don't skip this)

reinstall the cc desktop app, https://creativecloud.adobe.com/apps/all/desktop?action=install&source=apps&productId=creative-cloud

if you're unable to download the cc desktop app at this stage, use the "alternative download links" at the bottom of the page at https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html

use the desktop app to install your cc programs/trials
