I don't have iTunes installed, so I cannot tell you, what the right permissions are. However, I think the "Trusted Installer" will have to have at least some rights.
Maybe someone can look that up!

Here are the permission that my installation of iTunes has:
All Application Packages: Read and execute; Read
System: All except Special permissions
Administrators (on this PC): Same as system
Users (on this PC): Read and execute; Read
The installer/uninstaller is work fine on my PC so hopefully someone who is having the msi problem can tell us what permissions iTunes has on their PC. If so maybe we can solve this issue.
I agree with your concern about working in the registry. FYI, creating a restore point saves a copy of the registry so if a mistake is made it can be undone since there is no "undo" in regefit and any change takes effect immediately.
So as I understand it you are still not able to uninstall iTunes, right. If so then plz take a look at Halasz's post about CCleaner (free version). I downloaded it this morning and worked a bit with it. It's very nice. Be sure to go to the home site and downloaded it so you don't get a lot of add on junkware with it. I've read lots of recommendations for uninstalling damaged software with CCleaner so I think this might be your best bet at this point and you might avoid having to mess with needing editing the registry.
Before you use it I would create a restore point (tutorial is on this site) and also make a full backup of the drive your system is on, just for piece of mind. Then use CCleaner to uninstall iTunes and the other Apple software in the order that apple recommends. I think one of my earlier posts has a link to the Apple information. I have looked at the use guide for CCleaner and I think it work much like the windows version.
if anything goes wrong you can use the restore point and or the backup to undo everything.

Thanks for all your help so far - but as a novice I need a little help on this. I've created a restore point and I feel I should do a full backup. I use an external harddrive but it is FAT rather than NTFS, so it won't allow a system image to be created, which I presume would be the best thing to do. So I'm intending to convert my external drive to NTFS. On that drive I only keep backup and pictures. Websites tell me that converting is simple with no need to format, and no loss of data or anything, but I wanted to check with you guys who have been so helpful to me here. Is it ok to do this?
Doing a backup before you start is a good idea.
I have found this guide on how to convert the disk: Convert FAT32 to NTFS Without Formatting or Losing Data
I have not tested it, but it looks like these two simple steps would do the trick.
I agree with Joergi post but like him I have never done it although it appears to be straightforward. If you concerned you could always burn a DVDs of your pictures. It never hurts to have price of mind when you do something new.
UPDATE: One simple thing that you could try before CCleaner is to boot in Safe Mode and try the Apple update again. This would circumvent any third party driver conflicts that might be uninstaller finding the msi.

I've tried to convert my FAT32 drive to NTFS but eventually got the message: "the conversion failed" (I tried it twice - same result). I also tried the Apple update in Safe Mode but that didn't work either. I'll try Halasz's idea of using CCleaner to find the proper path for the msi file, and try putting it there. If that fails I could use CCleaner to uninstall all the itunes stuff (hopefully except the files) and then install iTunes completely new. Should that work?? But I've had enough for today! I probably won't be able to get back to this till Monday. Thanks again for all the help.
