The common thread in both errors is that the user does not have Administrative access to something. Are you using right-click Run As Administrator and have you turned off UAC warnings?
I am the administrator and I tried Run as Administrator trick to no avail. Adobe PS is the only software I have this issue with. I have tried turning off my Antivirus and firewall with no luck. Acrobat and Flash update by themselves with no problem.
I assume that you are trying to update from PS CS6? Could you try to going to help-update, and make sure camera raw 7.1 is there and checkbox is checked? Also, please let us know your current ACR plugin version/build number by “help-plugin-camera raw.” I assume you are on Windows. Thanks.
The update option in PS CS6 is greyed out, so I can't use that. Bridge cannot update, so I cannot use that. I cannot install the ACR 7.1 update manually. The version of CS6 I installed has ACR 7.0.xx. I'm not at home at the moment so cannot check plugin version, but will do that tonight. Yes I'm on windows 7, 64 bit.
BTW on my PC using CS5, Bridge can still update. These issues are on my laptop. I didn't always have these problems, they started suddenly a few months ago.

By some fluke I was googling the Adobe Application Manager and I came across a method for administrators to disable auto updates. Low and behold I discovered that a file had been created
C:\Program files(x86)\common files\adobe\AAMUpdaterInventory\1.0\AdobeUpdaterAdminPrefs.dat
that did indeed disable auto updates. As soon as I deleted the file Bridge found updates immediately and installed them.
I have no idea how that file was created as administrators have to do it manually and I have never done that.
Anyway problem solved.
Thanks to everyone for their help
