Installing Updates: Stuck at 0%

I am having the exact same problem -- been stuck at 0% for a couple days. It used to work. Not sure why it stopped, but would like a solution that doesn't require me to tinker with the inner guts of my computer where I'm more likely to screw more things up that fix something.

Perhaps this is a bit strange of me to put here, but I'm unsure if this is the right thread. Everyone seems to be having issues with CC updating itself, but not with the apps in CC? CC updated fine for me, but it's pretty much just stuck at "waiting" when attempting to update any of the apps in CC -- to 2015 version or not. It's been that way for hours.

I'm also stuck at 2% in Windows 10.  Have tried all iterations of killing tasks, reboot, uncheck update box.  Nothing works... updater hangs at 2% and Retry button does nothing.  Error 87 is displayed.

Mine was stuck as well so I did a Force Quit, reopened CC, the update notice came up, I unchecked the box that says "stay up to date", then ran the update. It started right away and took about 3-4 minutes to complete. Everything is working fine now after being stuck in 0% mode. Don't know why I didn't think of Force Quit before. I use it for other problems all the time.

iMac (27-inch, Mid 2010)

OS X Yosemite

Version 10.10.5

I went into task manager and then into the processes tab and ended all items using any adobe at all (as suggested above by rmintzes).  Then I restarted muse and started the update and it worked.  There was obviously a program using adobe that wasn't closing and holding it all up.  Try this as I spent hours trying everything else suggested and this was so simply and worked. 

The solution described by sarahb1087 in post #16 worked for me, too.

In what follows, I am drawing upon my 30 years experience in IT Technical Support.

Having read all the posts in this thread, I think there are two factors which we, as users, could and should give serious thought to.

1. Should we set Adobe CC to always keep itself up to date? That seems to have been part of the problem for some users.

2. Should we set Windows UAC (sorry, you Mac folks, I don't know what the equivalent is) to its highest levels? That also seems to have been part of the problem for some users.

I was running my Windows 7 system with UAC maxxed and "always update" set ON. I have now turned off "always update". Let's see what happens next time around. If the next update works OK, I'll turn "always update" back on and lower the UAC by one notch - and wait again for an update.

Let's face it, though, this shouldn't be happening. Adobe designers, coders and testers (both unit level and system level) have, collectively, failed. In this day and age you have to assume that, out there in the wild, there are large numbers of users who will have tinkered every which way with their system settings. You, the coders, must check the actual status of any system field upon on which you are going to base a decision BEFORE you actually use it. If you don't like the current status you then send an error message to the user and you STOP the install attempt. In respect of the two items I have mentioned above, you testers need to cover all four permutations: ON-ON, OFF-OFF, ON-OFF, OFF-ON. Right now your testing clearly leaves something to be desired.

Come on Adobe, get your act together. This isn't rocket science, you know, If NASA could consistently hit the moon in the 1960s you should be able to sort this one out in the 21st century. Or have the USA's coding and testing skills advanced backwards?

I'm a little late to the party, but I think I just found a solution.  My creative cloud installation of updates was stuck at 0% every time I opened it, even after turning my computer off and on, etc.  (I'm on windows) I opened my task manager (Control+ALT+Delete--> then process manager and right click to end tasks) and ended all adobe tasks manually, and then opened creative cloud again manually.  This allowed me to select "update" and the update and installation went through fine. I hope this helps!!

Computer re-start worked for me. Try this first...

The problem lies with the fact that Adobe Creative Cloud needs to ask you for Administrator Permissions to update. The system is refusing to allow the update as long as it has not received authorization from the user to run as an Administrator. The manual process asks correctly, allowing the system to continue. In order to get the updates to work, you need to close creative cloud completely (by ending the tasks through Task Manager) and cancelling the update when it tries running the next time it starts. It will then ask if you want to update or continue, which, when you click update, it will ask and run correctly.

In the future, just disable automatic updates for Creative Cloud until they can get it to where Cloud asks for permission to install on automatic updates.

It happend to me again today, while the adobe cc update manager wanted to update itself without asking. I killed all adobe processes and restarted creative cloud. That is where I saw the option 'keep creative cloud updated' and set this on to off. During update Windows would send the administrative notice on the software update.

In the prior situation there was no administrative message. But I think that creative cloud during this freeze with 0% is waiting for the answer on the administrative confirmation maybe?

Maybe Adobe could do something on this, as it seems every update this freezing issue occurs for thos who did not lower UAC level....
