Can't install Canon EOS Digital Solution disk

Question

Hi,
Have got a problem installing 'EOS digital solution disk' which came with my Canon EOS 400D digital SLR camera. Here is a description of what happens:
I click on 'CANON EOS Digital Installer' icon as instructed. First something called 'MasterInstaller' launches, and I select 'Europe' then 'UK' when prompted. The main menu appears again and I select 'Install', then 'Next' then 'Easy Install'.
I 'Agree' the terms, then hit 'Next' in Starting Installation window.
At this point, 'Installer' launches and a window appears with the text "Preparing to install ImageBrowser" (with a blue striped barber pole type line beneath) but nothing happens. The blue stripes do not 'move' as is normally the case when something is working. It just locks up, and usually the Mac beachball of death will spin. I've tried leaving it ages to sort itself out, but nothing changes.
When I go into the 'Force Quit' option from the pull down menu in Finder, (as everything is stuck) the 'Installer' and 'MasterInstaller' are usually highlighted in red, I guess meaning they've either crashed or got lost. Sometimes the Finder joins in too (being highlighted in red).
I'm not running any other applications, and I've tried doing a Custom Install, (instead of 'Easy') and choosing only 1 application at a time, and disconnected my external drive but to no avail.
I tried emailing Canon, but they have just suggested I try loading it onto another Mac but I don't have one or access to one either.
Some help would be appreciated.
P.S. Gave disk to my partner to try on his PC and he said it loaded ok, so I assume it's not a faulty disk.

So it still said Keys out of order ? That is a pretty serious error that Disk Utility rarely is able to repair. I would run it again and report to us exactly what is reported when you attempt a repair (not verify) please.
Hi Dale,
Well, the plot thickens....
I kept running the DU repair (about 5 or 6 times), and interestingly enough kept getting EXACTLY the same message:
Checking HFS Plus volume
Checking Extents Overflow file
Checking Catalog file
Keys out of order
Rebuilding Catalog B-tree
Repair completed
No details or other messages about what the specific problem was. (Is there a way to find out?)
Well, I took another look on the link you posted and ran an 'fsck'. (I still have no idea what that means but it sounded as if it may throw up some info.) Indeed it did and here's what appeared after I typed '/sbin/fsck -fy':
** /dev/rdiskOs9
** Root file system
** Checking HFS Plus volume
** Checking Extents Overflow file
** Checking Catalog file
diskOs9: 0x8 (UNDEFINED)
Keys out of order
(4, 1886)
** Rebuilding Catalog B-tree
diskOs9: 0x8 (UNDEFINED)
** The volume Mac Hard Disk could not be repaired.

(Hopefully there aren't any typos, I just typed this in myself, having written down the info on paper.)
Obviously the DU knows there's a problem, but simply thinks it's fixing it every time I run a repair. A bit like Groundhog Day I guess....
Now what??
