Acrobat Reader Updater won't quit trying to install old version.

Thanks, that looks very promising. I've deleted the LaunchAgent file(s) and hopefully that will permanently solve the problem.

The Adobe forums was my next stop, but I've posted there before, and rarely have gotten a helpful response. On the other hand, searching/posting to the Apple Discussion forums have almost always solved any problems I've encountered. Usually right away, so this place is the best. Thanks for your help CT!

Well, I did try that after 11.0.1 was released, but that didn't solve it. I see that 11.0.2 is out now, so I have just updated to it as well. My suspicion is the LaunchAgent tip is the more promising one, but only time will tell. Hopefully between the both of them this annoyance will finally go away!

Thanks!

I finally did find the solution. My MacBook Pro hard drive has three bootable partitions (one for Mountain Lion, Snow Leopard, and Windows 7). Anyway, I normally boot into 10.8, but I finally decided to try deleting Acrobat Reader from my Snow Leopard partition. That finally solved it. For some reason, the Adobe updater running on my boot partition was also scanning for applications on other partitions, but only actually trying to update the programs inside the boot partition's Application folder. Very odd. Now that only one copy of Acrobat is installed on both of my Mac OS X partitions, the problem has gone away. It's been weeks and no more annoying obsolete update notifications.
