How do I uninstall the Adobe Application Manager?
For Windows: Go to Control Panel>Program and Feature > and then uninstall the application.
For MAC : Go to the Application Folder and then uninstall Adobe Application Manager.
Or you may use the CC Cleaner Tool : Use the Adobe Creative Cloud Cleaner Tool to solve installation problems
Taunt, My problem is with a paid version of Lightroom 6 not creative cloud
It worked with Adobe Cloud Cleaner Tool. Why is it so complicated with Adobe products!!!
I understand, it is just some steps included.
So were you able to install Lightroom on the computer ?
