Can't Install iTunes, get message Can't uninstall previous ver of QuickTime

I'm the machine administrator, downloaded new iTunes for my new iPod Classic. iTunes installer attempts to uninstall old version of QuickTime but I get an error message that Can't Uninstall Old Version, Contact Support. Tried to uninstall from Control Panel, not! Windows XP Pro. Help!

It is the Windows Installer Cleanup Utility from Microsoft.
http://support.microsoft.com/default.aspx?scid=kb;en-us;290301
Here is an Apple document that gives more steps on it. Scroll down to the section titled
*General installation troubleshooting*
You need to click on all the links to expand them and get more info. THey show up blue on my screen.
My advice is to do those steps in order. The Microsoft tool directions are in the 3rd link named "Clean up iTunes installer files on the computer".

CAN'T OPEN iTunes, get message "can't open Error (-50)?

Can't open iTunes, get error message (-50)?

The 50 when launching iTunes can indicate a damaged Apple Application Support. So first I'd try a Repair install of your Apple Application Support.
Restart the PC. In your Add or Remove Programs control panel, select Apple Application Support, click "Change" and then click "Repair".
Does the repair install go through okay? If so, does itunes launch without the (-50)?

Can't Install iTunes : Error Message "Installer has insufficient Privileges to modify this File" Running Windows Vista

Hello!
I am currently having issues installing iTunes on BOTH of my computers. One running Vista, the other, Windows 7.
(Not the same issues)
I used to have iTunes on my Vista (32bit), but when asked to update the software (The update prior to the newest one), I was not able to.
I dont exactly remember the error message.
Yesterday, I tried to install it again when I realized there was a new update.
I am receiving an error message while trying to install the software that says :
"The Installer has insufficient privileges to modify this file: c:\program files\ common files \ apple \ apple application support \ webkit. resources \ inspector \ images \ warnings errors.png
I have tried almost everything I knew to do.
Downloaded itunes setup, extracted the files and tried to install them all separately.
Then I had issues UNinstalling Apple Support and Mobile devices!
Tried something with the registry (not too sure what. I read it on this website)
Tried to Force Uninstall EVERY bit of apple on the computer then try again, and to no avail.
I am a bit discouraged, because I have been trying for so long with both computers.
I even called applecare for help with Windows 7 computer. Spoke to one representative who forwarded me to another who could not help.
(Windows 7 itunes WILL install, but when I plug up my phone says I am not running 64bit itunes, which I am, and to reinstall. Then I was missing the Mobile device and would not let me separately install.)
I am a bit frustrated, and I'd appreciate all of the help I can get.
Thank You all in advance.

Can't install itunes... can't uninstall quicktime/itunes

I've searched the board and found a few threads about the error I'm getting.
When I try to install itunes on my machine, I get an error during the installation telling me that the installer could not remove the older version and I should contact support.
I've tried using the Windows installer cleanup utility and still it won't work.
I've tried the procedure from this thread and still nothing.
http://discussions.apple.com/thread.jspa?threadID=904330&tstart=90
FYI, there is no itunes listed in either my programs menu OR in the add/remove programs list.
Thanks.

It says at the begining of the install
"The Older Version of Apple Update software cannot be removed. Please contact your technical support group"
Then after it says
"The Older version of itunes cannot be removed. Please contact your technical support group"
Then it tells me itunes cannot complete the setup.
There is NO Apple update software or itunes in my add/remove programs list.

Can't install iTunes 10.5, can't uninstall Apple App Support

I have Windows7 64bit. I have read different threads about how to possibly remove iTunes completely. I have also tried to Install, Repair, & Uninstall all Apple related programs. Everything will uninstall except for the Apple Application Support. Everytime I try to install iTunes I get this error,
Could not open key:
UNKNOWN\Components\DA42BC89BF25F5BD0AF18C3B9B1A1EE8\00D5753BFE722C949B0E413B9D45 9E39.
Verify that you have sufficient access to that key, or contact your support personnel.
What should I do?

I was helped by an awesome IT friend of mine, here is what he had me do for my problem. I hope this helps someone.
First I toally uninstalled iTunes, Quicktime, Apple Software updater, ____-anything with Apple in the name.
I opened regedit using "run as administrator".
I then went to the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\ S-1-5-18\Components\DA42BC89BF25F5BD0AF18C3B9B1A1EE8\108B43C0CEA676640B35306AE7D 24051
...and selected the folder DA42BC89BF25F5BD0AF18C3B9B1A1EE8
Right click & choose permissions
click advanced, and then the owner tab
type "administrators" in current owners field and check th box to replace the owner on subcontainer and volumes
(Note: I did this because I had another key with permission issues after I fixed the original onelisted above)
Apply settings and then click permissions tab. Once again, add "administrators" to the list of permission entries, then click edit and check all permission boxes. Also click the 2 bottom boxes concerning the inheritable permissions.
Click OK
Now back on the main permissions tab, choose administrators in the group or user name window and then check full control and read checkboxes. Click OK.
Back in the main regedit window, you should now see keys in the right pane for each subfolder in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\ S-1-5-18\Components\DA42BC89BF25F5BD0AF18C3B9B1A1EE8
On the menu bar click file > exit

Can't install itunes - error message "the folder "itunes" cannot be found

Help. I just bought a new Iphone and can't get itunes to load. I had itunes on my computer for several years for my nano - haven't synced up in about a year. Went to open it and got the following error message
The folder "itunes" cannot be found or created and is required. The default location for this folder is inside Mu Music folder"
I have uninstalled everything - quicktime, apple mobile, every single file. I have rebooted, run searches to make sure there were no files at all left - did it through control panel, search etc., rebooted and downloaded it again (this make about 5 times now) and still get that same message that the folder cannot be found. Help! I just blew about $400 in the Apple store!
Can anyone help me?

Can't install iTunes 9 on Vista. iPod services have stopped?

I can't installed iTunes 9 on my Windows Vista PC. When I try to install, the installation process gets to about 95% complete, then an error pops up saying "Serice 'iPod Sevice' (iPod Service) failed to start. Verify that you have sufficient privileges to start the service". I also get a Windows System error that says "iPod service module (64-bit) stopped working and was closed". I can't install iTunes 9 and can't find any answers. And yes, I'm installing iTunes as the system Admin. Any help would be appreciated.
Thanks.

My problem is with Vista, but slightly different to the above.
I bought a new Vista PC yesterday and was able to download iTunes 8 to it.
I'm also still using my old XP PC until I get the Vista one properly set up. Last night I ran all iTunes/iPhone/iPod Touch updates successfully on the XP machine.
Today I am updating the Vista PC. Safari and Quick Time have downloaded.
iTunes itself reaches 98.7 of 98.8 verified and then fails.
The error message I am getting is ""The windows installer Service could not be accessed. This can occur if you are running in safe mode, or if the windows installer is not correctly installed. Contact your support personnel for assistance"
I have no idea what that means, does any Vista user know what the Windows Installer Service is and how I sort this out?
There is a pop appearing occasionally about setting up 'winlock' - I have no idea what that is (need to google to find out) so have ignored that until I understand what it is.
I've tried both running direct from the download and saving to my PC but still the same error message. Odd that the program installed yesterday but the updated version will not do so today.
Any assistance would be appreciated.

Can't install iTunes due to Quicktime failing to install

I'm on Vista (sad face) and over the past couple months iTunes has worked on and off...working and then I get an error saying "iTunes has stopped working" and then I have to mess with everything uninstalling/installing to get it working again.
However last week, when it happened I uninstalled iTunes and then attempted to uninstall Quicktime but it would not remove Quicktime off the list even after restarts. Then I ran the newest iTunes + Quicktime installer and it just goes until it gives me and error saying "The installer encountered errors before the requested operation for Quicktime could be compleated" and takes me to the complete box saying try again later. So the problem is with Quicktime because it won't uninstall/install and thus I can not install iTunes.
I have tried using the stand-alone Quicktime installer and have gotten the same error. I have also tried Apple Software Updater and no dice. I am getting very frustrated nothing seems to work and I need to update my iPod! Please help!
Thanks!

+I finally got QuickTime uninstalled (it wouldn't give me errors uninstalling, it just wouldn't uninstall) via Windows CleanUp Utility.+
After you used CleanUp, did you manually remove any leftover QuickTime program files?
If not, let's run through a CleanUp routine again.
Run CleanUp and remove the QuickTime entry.
1. On the Start menu, click Computer.
2. In Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx. (If “Hide filename extensions for known file types” is enabled on the PC, then those two files will appear as “QuickTime” and QuickTimeVR”.)
7. Restart your computer.
Next, we'll try to get a fresh copy of QuickTime into your PC by doing a repair install of itunes.
Switch off antivirus and antispyware applications prior to the repair install.
Go into "Uninstall a program" in your Control Panel (assuming here that you don't have Classic View selected) and select itunes. click "Repair" up at the top of the control panel screen.
If the repair install goes through okay, restart the PC and try launching itunes again. Does it launch properly now?

Are you trying to install the 32-bit version on a 64-bit machine, or vice versa?

I can't install itunes for windows get error message 5

i can't install itunes for windows get error message 5

I've been having the same issues for the past year and a half. I've spent 6-8months trying to figure it out. Went to various Itunes stores with pictures on my Iphone per each step so I could relay all information that I'd come across and the personnel were less than helpful, after conversations that would sometimes last an hour between myself, employees and managers they always came back to "simply uninstall then reinstall" when I told them for the thousanth time that I've done that multiple times and my errors are happening while trying to reinstall it they act stumped and say "well then I'm not sure, I'll give you a call if I figure it out" and disappear. I've been very disatisfied at the lack of support from Apple and if Android to piece together a reletively reliable phone I'd switch to them in a heartbeat. I'll follow this question incase someone can answer this, but I don't have much faith.
BTW, wifey has Windows 7 running on the laptop and my phone syncs just fine to that and no trouble with itunes, just mine (desktop).

Also, take a look at this Apple document -> Trouble installing iTunes or QuickTime for Windows.
