SOLUTION AS FOLLOWS:

NOTE: As always back up your system restore point and make a
copy of the registry or the sections of the registry
you are editing!!!
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

You need permissions set to the following registry paths under

HKEY_CLASSES_ROOT\itms\shell\open\command
HKEY_CLASSES_ROOT\itmss\shell\open\command
HKEY_CLASSES_ROOT\itpc\shell\open\command

You may not see these as you reset permissions and have to go as far as adding a new key under each registry key, then it will show you your newly added key (just delete) and then set the appropriate permissions to administrators group on each until you get down to the "command" key.

Then once you are in the command key edit the following string that should show

C:\Program Files\iTunes\iTunes.exe /url "%1"

and change it to...

"C:\Program Files\iTunes\iTunes.exe" /url "%1"


yes I know, ridiculous that it is a matter of quotes missing, but that is what fixed it for me.

From http://discussions.apple.com/message.jspa?messageID=5598778

The process is a little tedious but it will fix the problem.
U'll need to click the registry key and go to Edit -> Permission -> Advanced -> Owners -> Change owner to the current users
Then right click the key and go to permission and tick "Full Control" under Allow column
When moving from HKEY_CLASSES_ROOT\itms to HKEY_CLASSES_ROOT\itms\shell to HKEY_CLASSES_ROOT\itms\shell\open etc
You need to right click \itms -> "New Key" to reveal the \shell then repeat the process above until you reach HKEY_CLASSES_ROOT\itpc\shell\open\command and edit the string.

EDITED
No more tedious process
Please refer to post #4 for better solution.
