ITunes does not launch with new User Account (Vista)

Question

One of my limited user accounts on Windows Vista because corrupt, so I created a new limited User Account and copied ALL of the files from the old to new.
Now, when I try to launch itunes on the new user account, it will not open at all. Itunes works on my administrative account, with no problem.
Can someone tell me the most pain-free way to resolve this issue. And, whatever solution, will I be at risk of losing my itunes libraries?
Thank you in advance.

Hiya. Delayed again. Browsers being cranky. (I blame the aftershocks.)
It's actually plausible that it was installed in there (by doing a run as administrator on the installer itunes64setup.exe, perhaps). Because that suggests a possible cause for these continual permissions-related problems.
A lot of what you're seeing is consistent with damaged ACLs (access control lists) on files, folders and registry keys. Although it's a lot rarer than it used to be, one of the ways you could get borked ACLs was if a program (like iTunes or QuickTime) was installed in one user account, and then the user account it had been installed in was deleted (or otherwise rendered unusable).
We don't know which particular permissions are stuffed up here. But there's a shotgun approach to fixing them which used to work okay, although it's a bit fiddlier to do on a 64-bit system than a 32-bit system.
I'd strongly recommend setting up a system restore point prior to doing this, so you can revert if things turn to custard.
The basic technique you follow is from the following blog entry *with one important modification.*
[Solving setup errors by using the SubInACL tool to repair file and registry permissions|http://blogs.msdn.com/b/astebner/archive/2006/09/04/solving-setup-e rrors-by-using-the-subinacl-tool-to-repair-file-and-registry-permissions.aspx]
The modification is that when you're editing the file to replace YOURUSERNAME with the name of the account, edit the first line so that %ProgramFiles% instead says %ProgramFiles(x86)% and after the line that reads:
*subinacl /subdirectories %programfiles%\ /grant=administrators=f /grant=system=f /grant=users=e >> %temp%\subinacl_output.txt*
... add another line saying:
*subinacl /subdirectories %programfiles(x86)%\ /grant=administrators=f /grant=system=f /grant=users=e >> %temp%\subinacl_output.txt*
(The first is to make sure the commands see the subinacl, because it installs in \Program Files (x86)\ on 64-bit systems, and the second alteration is to make sure that the permissions for the 32-bit program files are fixed too.
After doing that (it'll take a while to run), can itunes launch normally in the new account?
