So I tried to uninstall everything and start again. When I uninstalled Quicktime it says "The installer encountered errors before the requested operations for Quicktime could be completed. To retry thee operations at a later time, please run the installer again"
The QuickTime problem is most likely causing the iTunes problem. So let's try uninstalling QuickTime by other means.
Download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
Now run the utility (“Start > All Programs > Windows Install Clean Up”), select any QuickTime entries in the list of programs that appears in CleanUp, and then click “Remove”.
Next, we’ll manually remove leftover program files and folders.
1. On the Start menu, click Computer.
2. In Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx. (If “Hide filename extensions for known file types” is enabled on the PC, then those two files will appear as “QuickTime” and QuickTimeVR”.)
7. Restart your computer.
Now download and save a copy of the latest standalone QuickTime installer to your hard drive. (We'll run the install from there rather than online.)
Latest Quicktime Installers … get the one that doesn’t mention iTunes
Switch off antivirus and antispyware applications prior to the install. Start the install by doubleclicking the QuickTimeInstaller.exe.
If that install goes through okay, restart the PC and try launching iTunes again. Does your iTunes launch properly now?
(If you get an error message when deleting files, using CleanUp or on the standalone QuickTime reinstall, let us know what it says. Include error message numbers if you're getting any.)
Thanks for answering^^
For some reason I couldn't delete the Quicktime folder.
When I go to program files to delete it, it starts deleting and then this box comes up saying "You need permission to perform this action" So I clicked Try Again but the the box comes up again. And when I click cancel it ends up cancelling the whole thing so nothing gets deleted.

Okay. That can be caused by damaged files or disk damage. (That would fit with iTunes and QuickTime stopping working to begin with, too.)
So let's try running a disk check over that drive. (This will probably take a while to complete.)
Quit all your running applications. Head back into "Computer" and right-click the drive that the Program files folder is on. Select "Properties", go to the "Tools" tab and click the "error checking" button.
Does the disk check find/repair any damage? If so, can you delete the folder afterwards?
So I enabled the disk check and it said it will check when I start my computer next time. I restarted the computer and disk check started. There were 3 stages. The whole disk check took like 2-3 minutes. The last bit went really fast so I couldn't read everything it said but I read Stage 1 and there wasn't anything wrong.
Hmmm. Something odd going on there.
Let's see if we can work our way around the edges of that issue.
At Step 4 of the instructions I posted earlier, instead of deleting the QuickTime folder, instead let's try renaming it QuickTimeOLD. (That way, the QuickTime installer won't try to put new files into it, later on, but will instead try to create a new QuickTime program folder.)
Then proceed with the rest of the instructions, as given.
... any joy there?
Okay. Let's change tack then.
If it's a permissions issuee, then you may be able to get control over that folder by using the following technique:
If you can get control, can you delete the folder?
