The folder "iTunes" cannot be found or created, and is required

I did a folder search. found itunes folder in: 1. user/library/itunes, 2. HD/library/documentation/applications/itunes, and 3. HD library/ documentaiton/itunes. tried to get one of the itunes folders into music as the error message stated. no luck. I still get the same original error message. All other applications appear to work properly. I'm just having problems with itunes.

itunes won't even load because it can't find the folder in music so I can't do the import suggestion. also, how do I "uninstall" itunes on a Mac; or, where is the "control panel" on a Mac? the only control panel I know of is in/on windows. I'd sure like to update my ipod.

MORE: I also dragged itunes to the trash and deleted it. I then reinstalled but still have the same problem.

I followed directions above and completely removed and re-installed itunes. I still get the same error message: "iTunes" cannot be found or created, and is required. the default location for this folder is inside the "Music" folder. How do I get the iTunes folder inside the music folder so the whole thing begins to work?

Still doesn't work. under information for the "Music" folder the permissions are" Owner = me/access = read and write, the group was "unknown" changed to adm/access read and write, others = read and write. clicked "applied" button and received the error code: The Finder cannot complete the operation because some data in "music" could not be read or written (error code -36).

Note, there appears to be NOTHING in the "music" folder and I can't seem to place anything in it.

I'm the only user here.

ran disk utility, repair permissions - the mssg said "stopped by user" (I didn't stop the repair) the msssg went on to say 1. determining correct permissions 2. privileges have been partially verified or repaired on the HD 3. permission verification complete.

Restart - ran permission repair again - repair complete - permissions verified and repaired - no error messages.

Restart: click verify disk - after the statement "checking the catalog file" in red 1. "invalid catalog record type" (I don't know what this means) and 2. "the volume macintosh HD needs to be repaired"

then "1HFS volume checked then again in red "volume needs repair"

then an error message droppped down "Disk utility stopped verifying Macintosh HD because the following error was encountered - The underlying task reported failure on exit.

Restart - tried again with the same results.

That's exactly what I did. When repairing the disk HD, I received the messages "checking catalog file." then in red 1. "invalid catalog record type", and 2. "volume check failed." The drop down error message said: "the underlying task reported failure on exit"

Why, my problem appears to be an iTune problem
