After installing the latest Mac OS X system update(10.11.4), I couldn't install Creative Cloud

Hi Tofusheng,

Please follow the below steps:

• Please check if you have any browser security extensions installed, please disable them. ( Eg: AD BLOCK, Mcafee site/web adviser, internet security toolbar etc )
• Also disable the Firewall of your machine see, OS X: About the application firewall - Apple Support
• Disable Firewall of the Internet security program installed on computer.
• Go to : Apple Icon > System Preferences > Security & Privacy > General > " Allow apps downloaded from " change this to ANYWHERE ( To make these changes click on the Padlock in the left bottom corner of this window and enter your computer password )

1- Force Quit the below processes in the same sequence as mentioned below from Activity Monitor: see, Use Activity Monitor on your Mac - Apple Support

• Creative Cloud
• Core sync & Core sync Helper
• CC library & CCX processes
• Adobe Desktop Common
• Adobe Update daemon
• Adobe IPC Broker
• After this anything that says adobe on it do a force quit for it

2- Go To: Finder > Applications > Utilities > Adobe Installer > Uninstall Adobe Creative cloud ( if having trouble uninstalling it Trash it )

3- Go To: Finder > Applications > Utilities > ( Delete these two folders - Adobe creative cloud and Adobe Application Manager )

4- Then run the cleaner tool to remove creative cloud and Adobe Application Manager ( if still left in machine )

5- Right click on Finder icon and  select "Go-To" Folder option.

8- Again > Right click on Finder icon and  select "Go-To" Folder option > You will get a text box, type-in below command and then hit 'Return' key.

/library ( It will open System Library folder.)

9- Then navigate to Application Support>Adobe> trash OOBE folder and Adobe Application Manager / after this rename the file SL-STORE as SL-STORE_OLD

10- Run Adobe Cleaner tool. > If present Select the option "Adobe Application Manager for Mac OS X 10.6" and then click on "Clean up Selected" . Use the Adobe Creative Cloud Cleaner Tool to solve installation problems
