No fixes have worked so far - please help!!!

Question

I've been reading through various threads for the last week or so to help me fix itunes after trying to upgrade to v5 but i've not been successful. Here's what i've tried so far, so any more guidance would be appreciated:
I've not been able to do the step by step clean uninstall of itunes or quicktime provided in the DaGopha thread - when I right-click on the bin folder in the ipod folder in program files and then choose delete, I get the following message:
"Cannot delete iPodServiceLocalized.dll: Access is denied. Make sure the disk is not full or write-protected and that the file is currently not in use."
When I right-click on the Quicktime folder in program files, I get the following message:
"Cannot delete QTTASK.EXE: Access is denied. Make sure the disk is not full or write-protected and that the file is currently not in use."
I then tried to use the windows installer cleanup tool but I cannot see itunes/ipod/quicktime in the list so have been unable to uninstall from there.
I tried installing 4.9 from one of the other threads anyway, but I get the message that a newer version of itunes is installed so it cannot continue. The itunes in the ipod program file shows as 4.8.0
I still have Quicktime on the computer but when i try to open it, I get the message "Quicktime failed to initialise. Error #2095. Please make sure Quicktime is properly installed on this computer."
I have tried to remove Quicktime via Add/Remove programs. When I click Change/Remove, I get the following message "The following file does not exist or is not a valid uninstallation log file. C:\WINDOWS\system32.QuickTime\Uninstall.log"
I also see "QuickTime for Windows (32-bit)" - does this need to be removed as well?
How do i completely uninstall itunes and quicktime and roll back to a previous version (preferably 4.8 as that's what i had, but 4.9 will probably do).
I know my problems aren't as severe as others as my ipod itself is still functioning ok as i haven't let it anywhere near my pc, but without itunes i can't add anything more to it. Any help would be appreciated as i'm going nuts!
Thanks (hopefully!)

Hi Amanda
Right, I'm going to try and pay back something that I owe cos these guys helped me fix mine. Mind you - it's taken me days and days! This is what Rachyl wrote (if you can find her threads, she's really good):
"OK try this:
1. Make sure you have that file called "mapi32.dll" found in your Windows/system 32 folder.
If you cant find it let me know, I can guide you through it.
Next, make sure All these are started: TCP/IP NetBIOS Helper, Windows Management Instrument, and WMI Performance Adapter.
How to do this: Click on the Start Menu;Right Click on my computer and then choose manage in that menu. In the left hand panel click "services and applications" and double click services. Find those files and then click them and see if they say started and automatic.
Next: download QuickTime 7 stand alone. http://www.apple.com/quicktime/download/standalone.html
If you are running mcafee or nortons, disable your firewall, antivirus and all that. Then restart
Next: Download Bonjour for Windows. Heres the link: http://www.apple.com/quicktime/download/standalone.html
Restart your computer. Remember if you have that anti virus crap, turn it off for the DL.
Next: Download apple itunes and restart, turning off all virus programs again. It should work from there. Good luck
Email me if you have probs and I will walk you through it.

In conjunction with her advice and Da Gopha's, I got it to work, although I did not download Bonjour in the final routine. Follow Rachyl's instructions about checking the TCP/IP etc are all running, and all the way until it says download bonjour. At this point, DON'T do that. Try downloading iTunes 5.0.1 that was posted most recently on the apple site. Make sure you reboot between each download and turn off the antivirus and firewall.
Hope it works and makes sense! - if you are still having problems uninstalling, let me know. I delved around in all sorts of places to find strange files that I deleted!
Good Luck!
