The installation of Adobe Extension Manager CS6 failed - while 2 others update for Photoshop CS6 did intall. I was installing Adobe Reader X .
That's why I discovered the notication from the application manager about updates for CS6 - and I just confirmed that as well.
Apparently the Reader installation blocked only the update installation of Adobe Extension Manager CS6 - saying another installation process was running ... such stuff happens sometimes.
However, it seems Adobes Application Manager update module does not track its failed installations? It does not automatically advertise that update has not been installed and notifiying me again to install it. At least not immediately ...
So how do I rerun the Adobe Application Manager update moduel to check for updates manually?
You go Photoshop CS6 > Help > Updates ...
