can not re-install itunes?

Hello CFoisy4,

It sounds like you are unable to install iTunes due to this error message. I recommend the troubleshooting in the following article that mentions this error message named:

iTunes 11.1.4 for Windows: Unable to install or open

http://support.apple.com/kb/TS5376

"iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows Error 126)”

Follow these steps to resolve the issue:

Check for .dll files

1. Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
2. If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
3. Reboot your computer.
   Note: Depending on your operating system, you may only have one of the listed paths.

Uninstall and reinstall iTunes

1. Uninstall iTunes and all of its related components.
2. Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
3. Re-download and reinstall iTunes 11.1.4.

Thank you for using Apple Support Communities.

Cheers,

Hi there,

Earlier iTunes (and supporting applications) need to be completely uninstalled before you can install the new version. Here's the complete Apple info on this: http://support.apple.com/kb/HT1923

Mobile device application will most likely fail to uninstall, so you would need to visit its location(s) and manually delete the files then folder(s). The location of the folders is documented in this link from Apple.

It's a pain, but it should work.
