Could not open key

Every time I try to upgrade QuickTime, a box opens saying: Could not open key
HKEYLOCALMACHINE\Software\Classes\QuickTimePlayerlib.QuickTimePlayerApp\CLSID.
Verify that you have sufficient access to that key, or contact your support personal.
PLEASE HELP

I have the same problem. I've tried every remedy I could find with google. Yes, I'm already in Admin mode. And I cannot edit the permissions in regedit because it just keeps saying Access Is Denied. I've tried uninstalling the K-Lite codec package because the problem registry key is:
HKEYLOCALMACHINE\SOFTWARE\Classes\.mpg
So I figured it must be a conflict with media file settings. Even though this didn't happen with my last iTunes install.
Now when I open iTunes I'm hit with a popup dialog before the program opens saying iTunes wasn't installed properly (it's still Version 7.5.0.20) and that CD tracks might not be displayed properly.
GAH! Please help!

Quicktime will not install to Windows Vista "could not open key..."

I have been trying to install Quicktime for some time.
Get error message: "Could not open key: UNKNOWN\Components\9c430...... Verify that you have sufficient access to that key, or contact your local support personnel." The installer then rolls back.
I kept trying and was able to install QT, but it would not open. Error messagesaid something about a "side-by-side" configuration.
I am the only user/administrator of this pc. I have tried all troubleshooting steps on this website, including uninstalling all Apple software and all remnants.
I tried all troubleshooting steps. My next step is to re-install Windows.

Doublechecking, Alex. Have you tried the procedures from the following post?

(Although that's about an iTunes install problem on 7 rather than QuickTime install problem on Vista, similar sorts of troubleshooting proicedures can apply in your circumstances too.)

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
keep us posted on your progress.

Could not open key UNKNOWN

I am having a problem upgrading from iTunes 9.0.07 to 9.0.2. I've been trying to use the 64-bit installer and have tried disabling my anti-virus software.
I had this same problem when I was running Windows Vista Home Premium SP2 64-bit on this same computer.
At first, when I would download, I had to Download Only and then install.
When I tried to install iTunes manually, it would load very slowly at Copying Files and then say it was Rolling Back Action. After that, it would say that, "The installer encountered errors before iTunes could be configured."
I tried everything people suggested on help forums, the discussions here, and the Trouble installing iTunes or QuickTime for Windows help article in Support.
After uninstalling iTunes, making a backup of my iTunes music from Documents and getting rid of anything else iTunes, QuickTime or Apple related, I tried downloading again from the website (using Firefox). I had the problem that iTunes said it couldn't be downloaded without QuickTime. Okay, easy fix, right? I tried downloading and installing QuickTime and these errors came up:
Could not open key:
UNKNOWN\Components\69413F169B198734FA40BC8B73511DB0\108B43C0CEA676640B35306AE7D2 4051.
Verify that you have sufficient access to that key, or contact your support personnel.
and

UNKNOWN\Components\9C4307835821FFF47864EE6DABC09AA9\EA2C92A1FBE18F42A12C111C5AAD DDA.
Verify that you have sufficient access to that key, or contact your support personnel.
So then I tried doing what jnd73 said in a different discussion: http://discussions.apple.com/thread.jspa?threadID=2151409&tstart=0&messageID=102 87668#10287668
And I found I couldn't do half of what jnd73 said. Either because it already knows I'm the admin, or because I don't have sufficient access to the key. I can't even get another admin user to download iTunes successfully. I don't know if it's a permissions issue.
The "The installer encountered errors before iTunes could be configured." problem started when I moved from Windows XP Home Edition SP3 32-bit to Windows Vista Home Premium SP1 (Had to update to SP2) 64-bit. I moved from a separate computer (Toshiba Satellite L35-S2151) to this one. I had to move all of my files from my last backup and re-download applications. I think what I did was I moved all of my old iTunes Program Files along with everything instead of just the iTunes folder in My Documents. So, when I downloaded the new iTunes, it didn't make new folders and used the old ones. I was able to make iTunes recognize all of the music I didn't buy through iTunes after I manually found the files, but iTunes never updated correctly.
I'd think now that I got rid of all of the old folders that now I'd be able to install without any problems.
Can anyone help?

I was having the same problem, but I found the solution to the problem.
First, click on Start and search "regedit" without the quotations. Open it up, click on "Edit: in the drop down menu. Next, click "Find" and search for your folder components, not the key component, which is in your case: 69413F169B198734FA40BC8B73511DB0
and
9C4307835821FFF47864EE6DABC09AA9
They should be folders, and inside the folders, there should be a key with the name of that 2nd key. Example, inside the 69413F169B198734FA40BC8B73511DB0 folder should be a key named 108B43C0CEA676640B35306AE7D24051, and the same for the other folder.
Now, to gain permissions for these keys, right-click on the folders, and select "Permissions". Where it says "Groups or User Names", click "Add". Then select "Advanced". Next, select "Find Now" and select the "Everyone" user. Click OK, then OK again, and you should be on the permissions window. For "Groups of User Names", select Everyone and select the "Full Control" check box for Everyone. Then click OK.
Do the same for the other folder. Be careful; for me, there was 3 folders with the same key name, and I repeated the steps above for all 3 in order to make it work. Just check the folders under your folder to see if it has the same name, and if it does, repeat the steps on that folder.
This method worked for me after trying a million different solutions. Hopefully, it works for you too. If it doesn't work, feel free to reply back. And if does work, please reply back, just so I know it did work.
Good luck =]

TS3299 Upgade error: Could not open key: HKEY_CURRENT_USER\SOFTWARE\Apple Inc.\Internet Services. Any advice?

During a standard iTunes upgrade to the latest version (11.1.4 for Windows Vista), the installation failed with the following error message: Could not open key: HKEY_CURRENT_USER\SOFTWARE\Apple Inc.\Internet Services. Does anyone have any advice as to how I can fix this and reinstall iTunes? When I try to open iTunes I get the following message: iTunes.exe. This application has failed to start because MSCVR80.dll was not found. Re-installing the application may fix this problem. When I try to run the installer I get the above error so I'm going round in circles!

Solved: I had somehow lost permission to access the HKEY above (or rather, its parent key HKEY_CURRENT_USER\SOFTWARE\Apple Inc.) so I went to the registry editor and checked the 'Full Control' box for the key and the installer now works.
I used this site to fix the MSCVR80.dll error: http://pcsupport.about.com/od/findbyerrormessage/a/msvcr80-dll-not-found-missing -error.htm

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)

Error 1402: Could not open key: HKEY_LOCAL_MACHINE... During Installation

Hello,
When I try to install LabView (v7.1 or v8.0) I get the following error:
"Error 1402: Could not open key:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\LVDB.Application\CLSID. Verify that
you have sufficient access to that key, or contact your support
personnel."
I have full administrator privileges on my computer and I am able to
modify that key manually using the registry editor. When I click the
"Yes" button to continue the installation it will complete but then
when I launch LabView I get the following error:
"The requested feature is unavailable on "localhost"".
Can you help me get LabView up and running?
Thanks,

The Adobe knowledgebase article actually pointed me in the right
direction and I was able to solve the issue. Thanks to all who gave
advise, you guys are the reason these forums work!
The error message was actually coming from the Microsoft Installer, not
from anything related to National Instruments. Also, ironically, what
the message said was spot on with one exception, while I personally had
access to the registry key, the installer didn’t. What I ended up doing
was going into the registry using regedit and setting the permissions
on the key in questions such that “Everyone” had full access. After
that I uninstalled LabView then reinstalled and it worked fine this
time. The step by step follows:
1) Open the registry editor by selecting "Run" from the start menu and then typing in "regedit".
2) Browse through the registry and select the entry mentioned in the error message.
3) Choose "Permissions..." from either the edit menu or by right-clicking on the registry key's parent directory.
4) Click the "Advanced" button to add a new user.
5) Type in "Everyone" as the new user and click OK (it may not be
necessary to give everyone full control but this is what I did and it
worked).
6) Configure the permissions for user "Everyone" to "Full Control"
7) Uninstall LabView (if necessary) and re-install.
Best regards,

'Cannot delete Quicktime.Quicktime: Error Deleting Key'. I then tried to export the key and recieved this: 'selected branch does not exist. Make sure correct path is given.'
Any help with a solution would be greatly appreciated

What I would do is go to registry key and try deleting it. If it does not delete, right click on it and choose permissions. Permissions need to be allowed for at least Administrator and System. If the key does not delete, move on to the next one that is asscociated with QuickTime and delete it, and go on deleting all the keys that are QuickTime related. The one that would not delete may delete after deleting the others.
Let me try to explain this the best I can. I am not a expert in the registry, but know enough to get in and out deleting a programs keys without having the computer become completely unfunctional. There are also books on it.
For example when I delete a program I also go into the registry and remove it, just something I do. Because after removing a program thru the add\remove program control panel and start>search>for all files and folders, there are still registry entrees.
When I start deleting keys in the registry from a program I'll normally run into one that won't delete, even after giving it permissions. So I'll by pass it and go on to the next key, related to the program. The one that wouldn't delete will come up again and end up deleting. So I seem to think that some of the keys inter-react with one another. Because the one that initially wouldn't delete now does after deleting the others, and sometimes giving permissions again.
If you want to delete all keys asscociated with a program. You can go to the Edit menu in the registry, choose Find, type in the name of the program and hit the Enter key on the keyboard. When the key shows up hit Delete on the keyboard. To get to the next key associated with the program, hit the F3 key on the keyboard and the next one will appear. This can get confusing because a registry entree can show up as a series of numbers, so your counting on the registry editor that, that key is asscociated with the program. As long as you are deleting keys that are associated with a program you are OK, if you delete something in the registry that you are not sure of, that is where you'll get in trouble.
You should try going to the path giving here to the registry. HKEYLOCALMACHINESoftwareClasses and try deleting those keys that are QuickTime and see if it resolves the problem.
