Problem installing iTunes 64 v11.4

Question

When I 1st installed iTunes 10 some time back, I followed these instructions: Ed Bott.  All worked just fine & I never had a problem w/iTunes or QuickTime.
I completely uninstalled iTunes & QuickTime to update both programs.  I couldn't find anything about installing iTunes 11 w/o bloatware, so I followed the above link hoping it'd be the same; apparently it's not.  QuickTime installed & is working just fine, but iTunes is giving me the attached errors.
Can anyone help me w/this?
My PC: Windows 7 Pro 64Bit w/SP1

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
Not an error message I recognise personally but the error has the same pattern as those discussed in the first and third boxes, suggesting that you've got an outdated .dll file that needs replacing. You should find AVFoundationCF.dll in the Apple Application Support folder. Delete it and then repair Apple Application Support. If that doesn't work go for the full tear down and rebuild.
QuickTime isn't needed unless you have certain older format video files or MIDI tracks in your library. I believe that Bonjour isn't needed if you don't want to use any of the library sharing features or wireless syncing and Apple Mobile Device Support isn't needed if you don't have any iOS devices. If you really need to worry about how much space these components take up then you probably need a bigger drive, but the main area of bloat is a bunch of .lproj folders used to support different languages when, presumably, you only need one of them,
