Unable to install iTunes because of QuickTime

I have a Windows 7 computer system. iTunes worked fine until I tried to update to the newest version. In the process I was told that the installation couldn't finish because a newer version of Quicktime is installed. I can't uninstall Quicktime. When I try I am told that there is a newer version installed. I can't find the newer version to uninstall. I followed advice to completely uninstall iTunes and the other components. I did it in the order suggested. Now I can't reinstall iTunes because of the Quicktime issue above. I now can't update my iPhone or iPad. Can anyone help?

Hopefully this will help people out who have no luck manually removing Quicktime or using the Microsoft Cleanup Utility.
When you try to install Quicktime it references a REGISTRY key called HKEYCLASSESROOT\Installer\Products\5B09BD67-4C99-46A1-8161-B7208CE18121 WinXp or
E7004147-2CCA-431C-AA05-2AB166B9785D Win 7.
This is where it reads what version you have currently installed. No where is there any reference to Quicktime in it. It took me a good 2 hours of hacking up and logging the install to get it to finally show me what it was trying to do. Delete these keys and search for any other. I can confirm that the key does exist on both Windows 7 and XP.
There is also a folder with the same name in C:\Windows\Installers\{5B09BD67-4C99-46A1-8161-B7208CE18121} or {E7004147-2CCA-431C-AA05-2AB166B9785D} that can be deleted.
After this you should have a smooth clean install of either Quicktime or Itunes

TS3212 I am unable to install itunes because "the installer has insufficient privileges to access this directory"

I am unable to install the newer version of itunes. I have no problem downloading but when it starts to install I get an error message that the installer has insufficient privileges to access this directory C:\ProgramData\Microsoft\Windows\StartMenu\Programs\iTunes
I am the administrator but it doesn't recognize it
How do I get around this?

Can't install itunes because of quicktime

My itouch won't register with itunes. A pop up for 10.1 came up, so I figured that was the problem. I started the download, but then I got two errors pertaining to quicktime. A box searching for the quicktime.msi destination, and "older version cannot be removed." I've tried downloading manually, it doesn't work. I've tried deleting both programs, STILL doesn't work. I've done a system restore - nothing works. I have no idea how to get itunes working again. I can't charge my itouch because it won't register. Any ideas?

Unfortunately, these sorts of msi-related troubles have gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any QuickTime entries and click "Remove".
Quit out of CleanUp, restart the PC and try reinstalling iTunes again. Does the install go through properly this time? If so, are you able to launch iTunes without the error message?
(If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

I am trying to install it on my desktop. I am also in Administrator mode. My iTunes stopped working when I was notified that there was a new version of iTunes and would I like to download it. I said yes as always and it was unable to finish the update because of a
runtime Error!
Program: C:\program Files (x86)\iTunes\iTunes.exe
R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contace the application's suport team for more information.
My iTunes stopped working at this time. I thought I could delete iTunes and start over. This tactic did not work.
Can anyone make sense of what I am saying and help me to get my iTunes back again?

Try a more recent version of my advice. The "for older video cards version" may work when the default version doesn't.
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.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

Unable to install Itunes 10.1 or 10.1.1 -Apple Mobile Device USB Driver

Unable to install Itunes 10.1 or 10.1.1 and have it sucesfully install the Apple Mobile Device USB Driver. It keeps coming up with an error that the driver is unsigned or disappears completely from device manager.
I have tried full uninstall including cleaning registry keys and file system. If I uninstall and re-install 9.2.1 usb driver works perfectly and I have no issues synching with phone or seeing the phone in Itunes.
I have tried repair installs, updating the drivers by pointing to C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers
I have tried removing all USB devices and having them reinstall from Windows after a reboot. Nothing seems to work.
I just got a new IPAD and cannot use it because I cannot install 10.1 at least to have it connect. It came with IOS 4.2.1 on it.

I also encountered the same problem.
and yes, I uninstalled and reinstalled itunes 10.1.1 bla bla blahhh....
Same issue!!! itunes cannot open cuz the mobile device support not started etc..
but when reinstalled prior itunes version 9.2 its gone
and issue fixed.
i can sync my 3G.
but not my 4G. it says you need to upgrade to 10.1 or above
spending the whole night to fix the problem which never occured b4
i finally find out one thing.
pl keep in mind im not a computer exprt
i tried this and it worked, i don know what fixed it, bt it works
try this at your own risk. some comp genius will tell us weather this way is right or not.
ok. lets start...
in your desktop make a new folder. name it Kmh_\CoreFP
try uninstalling the newer version 10.1
only the itunes not other mobile div suprt, application suprt etc.
dont mind the following order:http://support.apple.com/kb/HT1923
and reinstall itunes 9.2
go to C:\Program Files\Common Files\Apple
you wil find a folder named "CoreFP"
copy it and paste to Kmh_\CoreFP
uninstall itunes 9.2
and reinstall itunes 10.1 again
go to C:\Program Files\Common Files\Apple
you wil find folder named "CoreFP"
find the difference in properties comparing the one u stored in Kmh_\CoreFP
ok delete it and replace it with the one we stored stored in Kmh_\CoreFP
restart the computer and start itunes now
what happens?
best of luck.
-Kmhm63
reinstall the newer version 10.1
I would suggest that you revert back to prior working version until Apple comes out with an update that fixes what 10.1.1 broke.

Unable to install itunes for new computer with windows 8

unable to install itunes for new computer with windows 8
states this app unable to run on this PC

Hello jgrn76,
It sounds like you are getting an error stating that the iTunes installer cannot be run on your computer. I would try downloading the 64 bit version of iTunes from here:
iTunes 11.1.3 for Windows (64-bit)
http://support.apple.com/kb/DL1615
If issues persist when trying to install it, I would try running through the steps in the article named:
Issues installing iTunes or QuickTime for Windows
http://support.apple.com/kb/ht1926
Otherwise, would you mind elaborating a bit on what the error message says, word for word?
Thank you for using Apple Support Communities.

I am unable to install itunes. I get the pop-up asking if I want to save or cancel the iTunes64 file. I click save... and then nothing happens. Help!

I'd first try downloading an installer from the Apple website using a different web browser:

If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

Hi Nitro,
Tried your advise but that too failed. Problem still continues. Again that same error "There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor".
Please advise.

Unable to install iTunes after converting from Windows Vista to Windows 7. Am told installation was successful, then "iTunes was not installed correctly", followed by "Error 7 (Windows error 193). I have my iPod plugged into my computer via USB port. What am I doing wrong?

I have the same problem and

went to Apple to download itunes,
hit download now,
Visit the iTunes download page. Click Download Now to download the iTunes installer. When prompted, click Save (instead of Run).
did not get a save instead of run prompt
Right click on iTunesSetup or iTunes64Setup (the installer you downloaded in step 3).
If you have Windows Vista, Windows 7, and Windows 8: Choose "Run as administrator."
i can only click run as administrator from right clicking the shortcut on my desktop screen
If iTunes fails to install or repair, it might be necessary to remove components left from a previous installation of iTunes and then reinstall.

Perhaps let's first try updating your Apple Software Update.
Launch Apple Software Update ("Start > All Programs > Apple Software Update"). Does it launch and offer you a newer version of Apple Software Update? If so, choose to install just that update to Apple Software Update. (Deselect any other software offered at the same time.)
If the ASU update goes through okay, try another iTunes install. Does it go through without the errors this time?

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any Bonjour entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

I am still unable to install itunes in Windows Vista

I have tried to run Fix it 4 times now after doing other things suggested in the Apple community and I am still unable to install itunes. Do you have any other ideas?
I've been uninstalling/reinstalling and using CCcleaner, sfcscannow and nothing seems to correct error msg 2- corrupt files found/unable to fix. Now what??????
I am using windows Vista. I NEED help!

nothing seems to correct error msg 2
With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)
