Could not open key UNKNOWN/Componets

I keep getting this error, with a long string of letters and numbers after it. I dont feel like typing it out when I could just enbedd a screen shot, which I have put here:

[IMG]http://i254.photobucket.com/albums/hh104/wuzupmyhomiz/Untitled_zpsa0d0b35a.png[/IMG]

I have googled it several times, tried TuneUp Utilities, Ccleaner, I tried looking in regedit, and I couldnt find the file that it was asking me to modify the permissions for.

I just got a iPhone 5 yesterday, and I really want to set this bad boy up with VLC streamer and some music.

Thank you for any help! If you have ANY suggestions, please post!

iPhone 5, iOS 6, iTunes(Latest Version,64bitversion)

Doublechecking. Have you tried the following user tip?

"Could not open key: UNKNOWN\Components\[LongStringOfLettersAndNumbers]\[LongStringOfLettersAndNumbe rs]" error messages when installing iTunes for Windows

Yes, and unfortunately I keep getting that one particular error it lists in it, and I keep trying to r-install as it says, but the same error occurs, and the instructions dont say what to do if it doesnt work.

Okay. Let's give the fixit from the following Microsoft document a try. (It's efficacious against a class of these that don't respond to the user tip, although not all of them.)

Fix problems with programs that can't be installed or uninstalled

Are any of the related software components appearing? (Apple Application Support, Apple Mobile Device Support, Apple Software Update, Bonjour?)

Yes, I found Apple Software Update, I removed it and tried to re-install, but couldn't get it to work, same error.

I'd also like to note that I got it to work before, I had iTunes before on this computer

Okay.

Have you been using the "problems installing" or the "problems uninstalling" mode with the fixit?

I try using one of the modes to remove it and it asks for a program I.D. And I tried googling for it with no search results to be found.

Trying another tack. Going back to using regedit rather than the Fixit.

Try heading back into the "Permissions for Components" screen shown at step 12 of the Tip instructions:

(12) In the "Permissions for Components" screen that comes up, click the Advanced button:

Select Administrators, check "Full Control" under Allow, and click OK.

Repeat for any "Users" entries showing up in there.

Try the install again. Any better luck?

🙂 Not quite. In the current version of the user tip, we haven't been touching the permissions in the screen ... we've been heading straight to the ownership. Changing the ownership doesn't necessarily change the permissions. There seems to be a class of these that only respond to the ownership change, and a class for which we have to also change the permissions.

(Done enough live human experimentation on this in the past tweo days, that I'm just about ready to amend the user tip to try to catch that latter class of the problems.)
