uninstall your adobe bridge, and then reinstall it.
NO PROBLEM SOLVED
I am experiencing the same problem as the original poster (OP) of this thread. Like the OP, I also have the same updated versions of both programs. I uninstalled and reinstalled both Adobe AE CC and Adobe Bridge CC. STILL, the problem exists. Adobe Bridge CC still works with the other programs (Photoshop, Audition, Illustrator, etc.) but not After Effects.
I also did a CLEAN install on a second boot-up drive to my well-functioning and up-to-date MacPro; did a clean install of both AE and Bridge (as well as some of the other Adobe Cloud programs). Again, I am getting the same message that the Adobe Bridge program needs to be installed.
Humph. . .
Is there a solution to this problem? if so, what is the solution?
Thank you for your response. Unfortunately that didn't work. Oh well. . . .
Thank you for your thoughtful response. I tried this. Unfortunately it did not work. Not sure what else to do.
try resetting your ae preferences: http://helpx.adobe.com/after-effects/using/preferences.html
if that fails,
uninstall everything cc including the cc desktop app.
clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
restart your computer (don't skip this)
reinstall the cc desktop app, https://creative.adobe.com/products/creative-cloud
use the desktop app to install your cc programs/trials
