I have had an extraordinary amount of trouble with the Creative Cloud since CC 2015 was released (I subscribe to the Photographer CC and get Lightroom CC, Adobe Camera RAW, Photoshop CC, and Bridge CC).
On numerous occasions I have experienced "Download Failure" and "Install Failure" with error codes that include the one shown above.
On multiple occasions I have contacted Adobe Technical Support. In some cases they have "taken control" of my computer to address the issues. While some of those sessions have resulted in getting an update installed others have resulted in bad advice, fixes that didn't work, trouble with Add-ons, and generally not fixing the problem. I have concluded that Adobe doesn't know what they're doing.
I am still unable to consistently and successfully download and install updates to Lightroom CC(2015) and Photoshop CC(2015).
The only way I have been able to continue using Lightroom and Photoshop is to get the updates from ProDesignTools at this website:
http://prodesigntools.com/adobe-cc-2015-updates-links-mac.html
Currently I have Adobe Photoshop Lightroom CC 2015.3 Release, Adobe Camera Raw Version 9.3.0.506, Adobe Photoshop 2015.0.1 Release, and Adobe Bridge 6.1.1.10 installed and running on both my MacBook Pro and Mac Pro computers. Both computers are running OS X 10.10.5.
If I click on the Creative Cloud menulet and go to Apps, it says that there are updates for Photoshop CC(2015) and for Bridge CC. When I click on What's New it says that I need Photoshop Camera RAW 9.3(CC).
In the past I have tried multiple occasions of signing in out and back in to Creative Cloud. I have uninstalled and reinstalled Creative Cloud, Lightroom and Photoshop.
Complaints to Adobe have resulted in messages to call them (the same people who, in the past, have had to go to the knowledge base), change file permissions, and other arcane approaches. The problem is that I no longer trust what they say.
It's pathetic that I have to pay Adobe $9.98/month and yet depend on a third party to get updates.
Would appreciate any recommendations - including a possible tech contact at Adobe who is competent.
Thanks. Rant complete.
