ITunes fails to update - 'Could not open key...'

I am having trouble installing the latest iTunes update bith through Apple Update and by trying manually.
I get a 'could not open key' error followed by 'UNKNOWN/components/.......'
Quicktime updates fine but Safari 5, iTunes and iCloud Control Panel all failed with the same message.

ITunes 10.6 error 'Could not open key...."

Hi there, so i was installing the new version of iTunes (10.6) and then in the middle of the process a box came up saying "Could not open key:UNKNOWN\Components\ ~~~~a lot of numbers and letters~~~~~\ ~~~~~~a lot of numbers and letters~~~~.Verify that you have sufficient acess to that key, or contact your support personnel.
Right now i have 3 different keys that show up during the installation, each in a different box.
I've tried to change in the regedit the permission of those keys, but it seems like didn't work.
So if anyone can help me please, i'll be very greatful.

"Could not open key:UNKNOWN\Components\ ~~~~a lot of numbers and letters~~~~~\ ~~~~~~a lot of numbers and letters~~~~.Verify that you have sufficient acess to that key, or contact your support personnel.
These ones are tricky. But the following instructions are worth a try.
First do a complete uninstall of iTunes and related components (but don't reinstall just yet), as per the following document:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
a. Launch regedit (Start >> Search Programs and Files >> type Regedit and open the regedit that comes up.)
b. Access the following Location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData \S-1-5-18\Components
c. Perform the following actions
i. Right Click on Components Folder
ii. Select Permissions
iii. Select Full Control and Read Permissions options
iv. Select Advanced Button
v. Select Owner Tab
vi. Select to Change Owner to the Administrators
vii. Check the option “Replace owner on subcontainers and objects”
viii. Select OK when prompted that it may not change all.
ix. Select Apply
x. Select Apply again
xi. Exit the Registry Editor
Now try reinstalling iTunes again. Does it go in properly this time?

ITunes 10.6 Error-Could not open key UNKOWN/Components...

Hi guys, I've been trying to install iTunes 10.6 on Windows 7 64bit, and keep getting this error.."Could not open key: UNKNOWN/Components/EC902C4A3C46DD11393FC916558D5939/21DFF8FCB206D224FAD115B114E 16723. Verify that you have sufficient access to that key, or contact your support personell." I really don't know what to do, I've tried a lot such as making sure it's uninstalled, using Windows Installer Clean up to remove Bounjour, Quicktime and iTunes. I've also tried running the installer in Administrator. I would really appreciate it if somebody could help me! Thanks!

Hmmmm.
Just in case, let's try the Fixit from the following document:
Fix problems with programs that can't be installed or uninstalled
(One of the things it does is check on installation patch registration ... which is associated with a related set of registry keys. I'm not sure how they're implementing the patch registration tool in the automated Fixit, but ... fingers crossed ... it might also be of some help with the \Components\ keys we're having grief with here.)

Trouble installing updates. "Could Not Open Key: UNKNOWN\Components\DA42BC89BF25F5BD0AF18C3B9B1A1EE8\7E577B2224C65CF4E801A9E5237 5DB49. Verify that you have sufficient access to that key, or contact your support personnel."

I am having trouble installing updates from iTunes. It used to work flawlessly. I am having trouble finding an email address where I can contact Apple or iTunes. I do not want to take the chance that they will charge me for a phone call because I think it is unfair for them to charge me, since I am using THEIR software already. THEY NEED TO PAY ME!!
Here is the error message I receive each time I try to install the updates:
"Could Not Open Key:

If someone would be kind enough to help me, I would greatly appreciate it!!
THANKS!!!!!!

2. Right click in Media folder, select Permissions from the menu.
3. You will see that is no user, on the "Permissions for..." dialog box which appears next, press the "Add.." button and add in the "All"
4. Back on the first "Permissions for..." dialog box, click on each account in the top-list and make sure each has the "Full Control = Allow" and "Read = Allow" permissions
5. Click the "Advanced" button and the "Advanced Security Settings" dialog box appears
6. On the "Permissions tab" enable the checkmark box named "Replace all child object permissions with inheritable permissions from this object", then press the "Apply" button
7. On the "Owner" tab, highlight the "Administrators" name in the lower listbox, enable the checkmark box called "Replace owner on subcontainers and objects" and press the "Apply Button"

Could not open key....itunes fails to install

Running Xp sp 2 and logged to administrator account. The entire package including quick time, bonjour, software update, etc...successfully load and function; installer loads all itunes software until it reaches process of "writing registry values" and then hangs with error:
could not open key: hkeylocalmachine\software\mozillaplugins\@Apple.com\itunes, version= verify you have sufficient access to that key, or contact your support personnel"
under regedit, checked permissions on this key and "allow" "full control" are checked for the administrative profile that is logged in, so there should be access to that key. Tried disabling security software, uninstalling and reinstalling the entire package and while everything else will work, itunes still will not install; any suggestions that don't include an axe or sledgehammer appreciated.

under regedit, checked permissions on this key and "allow" "full control" are checked for the administrative profile that is logged in, so there should be access to that key.
Just doublechecking an exotic possibility. Does your SYSTEM account have full control of the key, too? (Peculiar things can happen when that loses permissions on a key.)

Win 8.1 Pro, iTunes install fails with "could not open key"

Have tried complete uninstall as required by "Remove and reinstall" Did not work.

Okay ... although you've got a Windows 8 (rather than a 7 or a Vista), let's try the following user tip:

You could try using the Windows Installer Cleanup Utility to remove all traces of any existing versions of Reader prior to installing the version you want and updating it as required. This utility is no longer supported by Microsoft because it can conflict with Win 7, but you can still find it in sites like http://majorgeeks.com/download.php?det=4459

ITunes 10.7 installation error: "Could Not Open Key," etc. & Privileges error

When attempting to download iTunes 10.7.0.021 (latest version for iOS 6 compatibility with my new iPhone5) I get the following error:

This error pops up in the middle of my iTunes installation; After hitting okay, the installation proceeds and then another error message reading:
"Apple Mobile Devices Failed To Start. Please make sure you have sufficient privleges... etc."
I don't know what to do about both of these errors, so if you find a solution please e-mail me: [email protected]

HELP ME!!!! itunes wont open, error says could not open key......

I attempted to update itunes to the newest upgrade, and the upgrade was unsucceful, and now this error comes up everytime i try to open itunes (it wont open at all). the error says
Could not open key:
HKEYLOCALMACHINE\Software\Classes\.wav\OpenWithList\iTunes.exe.
Verify that you have sufficent access to that key, or contact your support personnel.
This makes no sense since this is on my home PC

hmmm. okay, if you're currently just getting the "itunes has encountered an error ..." let's try the following technique.
preliminaries
download and save a fresh copy of the itunes 6.0.1.3 installer to your hard drive. (eventually we're going to run the install from there rather than online.)
iTunes 6.0.1.3 Installer
switch off any antivirus and antispyware applications prior to any uninstalls, installs or repair installs.
uninstall
use the complete uninstall instructions given in the following document to remove your existing itunes and quicktime:
Troubleshooting iTunes, iPod Software, and QuickTime installation on Windows
... and if you run into problems on the uninstall, try using the Installer Cleanup utility:
Description of the Windows Installer CleanUp Utility
reboot after uninstalling.
reinstall
remember to switch off your antivirus and antispyware.
reinstall itunes using the 6.0.1.3 installer you downloaded previously.
if you get the "itunes has encountered a problem ..." error message again after that install, first check to see if your Quicktime will launch. if you get an error message when you try to launch quicktime, try using the following technique:
iTunes 6 for Windows unexpectedly quits when opened

Tried to install ios5. Would not install. Also lost earlier version of itunes. Keep getting message Could not open key

Tried to install the newest version and lost all itunes on this computer. Followed instructions about removing and reinstalling iTunes, Quicktime, etc. Now I get message "Could not open key: UNKNOWN\Components|" and several letters/numbers afterward.

The first thing would be to get the proper version of Safari for your version of OS X (Tiger).
Go here to get Safari: http://www.apple.com/safari/download/
Be sure to choose the bottom choice:
You will also need the latest security update for Tiger.

For "Could not open key/write value" errors when reinstalling try b noir's user tip:
"Could not open key: UNKNOWN\Components\[LongStringOfLettersAndNumbers]\
[LongStringOfLettersAndNumbers]" error messages when installing iTunes for Windows.
The technique can be applied to the branch of the registry mentioned in the error message.
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.

Could not open key:
UNKNOWN\Components\DA42BC83BF25F5BDOAF18C3B9B1A1EE8\3e43b73803c7c394f8a6b 2f0402e19c2. Verify that you have
sufficient access to that key. or contact your support personnel.
After following instructions for three different solutions that did NOT work; I found the solution that did work
on the support site for Syamntec.
Readers - Please, you must be VERY familiar with pc jargon and windows vernacular to accomplish the reset
of ALL the permissions in your registry.
Follow the ditrections below and pay attention to the notes for those running 64bit Win7.
Step one, back up the registry.
Step two, go to the MS KB: http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf -ed6985e3927b&displaylang=en and download the file that installs subinacl. It is an MSI file, and will do a quick install of a few Microsoft files. Hint: Look in the folder listed below, "subinacle.exe" may already be there.
Step three, create a batch file (subinacle.bat) with the following commands: (Use Notepad - copy & paste, not the red stuff)
cd /d "Program Files\Windows Resource Kits\Tools" (only for 32bit/x86 machines)
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
For 64bit machines substitute for first line of bat file:
cd /d "c:\program files (x86)\windows resource kits\tools"
Step four, run the batch file. Let it run until the Command Prompt screen closes, may take 30 minutes or more.
Step five, reboot the machine and run the install again.
Ladies and Gentlemen; this worked for me and allowed immediate installation of two application packages I had been trying for three months! (Including ITunes 10.5)
