Quicktime missing....need to reinstall itunes

Question

First post and would appreciate any help!
I deleted an older version of QT and installed a newer version. Now Itunes won't open and it tells me it can't find QT and "reinstall" new version of Itunes. If I do this, where will all my music in my library go? Do I uninstall the version of Itunes I have on my computer? I have 1500 songs and don't want to lose them! Would appreciate any help!!! thanks

QT is showing on my all programs in windows. Click to open and get error message: QT failed to initalize. Error # -2093. Please make sure QT is properly installed on this computer..
okay. it sounds like the upgrade of your QuickTime didn't go through properly.
let's try swapping it out, taking a few additional explicit precautions with the uninstall/reinstall..
first, head into your Add/Remove programs and uninstall QuickTime.
Next, we’ll manually remove leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My 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.
7. Restart your computer.
Now, download and save a copy of the QT 7.1.6 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
Quicktime 7.1.6 Installers … get the one that doesn’t mention itunes
if that install goes through okay, does your itunes launch properly again?
(if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)
