Eitehr the programs are up to the latest or something is blocking the updater. Impossible to tell, since you did not provide any info. Try downloading the updates manualyl from the Adobe page. If they don't apply, consider uninjmstalling the programs, running the Creative Suite Cleaner Tool and reinstalling.
thank you so much for your efforts!
I found out, that in DeviceCentral the update link is not greyed. A click on it causes a window (Adobe Application Manager) with to messages (translated from german):
1. 'Some updates coudn't be installed'
2. 'Updates are deaktivated'
Photoshop is running with version 12.0.3
Hopefully it is more clear to you now.
Thank you in advance!
