I own single user Lightroom 6 for some reason when I check for updates on my desktop Creative Cloud update

Hi Kafloyd71,

Please follow the below steps and try again :

Mac -

1- Turn OFF any security software installed along with system Firewall.

2- Please check if you have any browser security extensions installed, please disable them. ( Eg: AD BLOCK, Mcafee site/web adviser, internet security toolbar etc )

3- 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 )

****These changes are temporary you can revert these changes back to normal once your Creative Cloud app is up and running ****

Win -

1- Turn OFF any security software installed along with system Firewall.
