The Extension Manager 6.0.8 Update failed on my iMac 10.9.2 with the Error Code U44M2P7. I am running Photoshop CS6, version 13.0 x64 on my iMac. I have tried installing this requested update from within my PS CS6 software installed AND also from downloading the update from the Adobe web site. Both attempts give me the same Update Error Failed message above.
Also, I have no idea what version of the Extension Manager I should be updating to. I see there is a version 7 available.
Also, I cannot find a phone number to call Adobe for technical support.
NOTE: I am not running the Creative Cloud version on my iMac.
