I have Adobe Photoshop CS5. Adobe Application Manager has always given me access to updates to the relevant parts. Lately, it says that I need to update to Photoshop 4.0.4 and Bridge 4.0.4 but I have Photoshop 12.0.4 installed and Bridge 4.05.11. When I tell AAM to update, the "updates" are downloaded but installation fails. AAM does not allow me to uncheck one of them at a time; it's both or nothing.

I logged into test account and AAM told me that Photoshop CS5 and Bridge CS5 are up to date (and, indeed, they are because I checked Adobe's website for relevant updates). This leads me to believe that a preference file is corrupted in my main account but, despite searching, I can't find anything that resembles an AAM plist.

Does anyone know its location?

Have you looked in Application Support?

Yes, but not thoroughly. There is a ton of stuff in there and Adobe may or may not name those files via Apple conventions.

As it turns out, while you were responding, I went to Adobe, downloaded an update to AAM and installed it. Everything seems to be working now.

EDIT: Just now, I looked in ~/Library/Application Support/Adobe/AAMUpdater/1.0 and found AdobeUpdaterPrefs.dat. I don't know if that's the guilty party because I just updated to AAM 2.0, having been at version 1.0. At any rate, all seems to be well now.

You must have meant that I should look in ~/Library/Application Support, not /Library/Application Support. If the latter had been involved, I would have had the problem in the test account.

Yup! (I'd expect an item like that to be somewhere in ~ under any circumstances.)
