This error comes when Updates are not able to identify the base product installed.
Please ensure that in Ps->Help->Update->Preferences, Updates list is as per the products installed on your system.
If not please re-install them.
I found in my updates list that I have camera raw 7and 8 installed on my pc , I found that the updade was for ACR version 8 so I turned off updates for 7 and now CC is telling me that all aplications are up to date....was this the correct thing to do ?
I'm running into the same problem - getting the U44M1P34 error when trying to update the Camera raw plugin. I've uninstalled and re-installed AE and PS three times each now... no luck. Do I have to uninstall ALL Adobe applications for this to work?
