Trying to deactive Lightroom 5 on my old iMac and activate Lightroom 6 on my new iMac. Adobe Instructions state that you go under "help" to sign out (deactivate) a computer or activate one. Lightroom 5 does not have an activation/deactivation option listed under the help menu. These are both desktop versions not "CC" versions. Any suggestions?
May i know have you upgraded to lightroom 6 from Lightroom 5.
LR5 doesn't use activation, so you don't need to do anything.
Although you don't have to, you can uninstall it if you wish.
Your reply got me thinking and alas I did have Lightroom 6 activated on the old mac, but 5 kept coming up. Brought 6 up on the old machine and deactivated it. Then was allowed to activate on the new mac. Thanks for the reply
