Neither the ACR nor the Lightroom CC 2015.5 update shows app in my creative cloud. I downloaded the installer for ACR and that didn't work either.
Try Signing out then Signing In to the Creative Cloud app.
The Apps page should show the buttons for LR, PS & BR as [Update] Click to do!
ACR installer is NOT required!- ACR will install with the PS update, Lightroom does not need ACR, it is built-in to the LR program.
