Can't launch iTunes due to previous version of QuickTime installed

I installed an older version of QuickTime, now I can't launch iTunes anymore. In Control Panel, I have QuickTime 32--version 2.11.57 listed. I did everything in the document http://discussions.apple.com/thread.jspa?messageID=3366434&#3366434
but nothing has worked. I can't seem to uninstall the old version of QuickTime. When I run QTInstaller713.exe I get an error message about "Can't install because a newer version is already installed"
Sony Vaio VGN-S260 Windows XP

There are no QuickTimes listed in the Add/Remove list. I see it listed in the Control Panel where there is a QuickTime and a QuickTime 32 (v2.11.57). I also see it in Start > Programs > QuickTime. When I click on that I get the message: "This action is only valid for products that are currently installed."

Hey bcolden,
I would try uninstalling and reinstalling following the directions in here:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
http://support.apple.com/kb/HT1923
This section in particular contains important information in the uninstall process:
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Important: Uninstalling these components in a different order, or only uninstalling some of these components may have unintended affects.
Let us know if following that article and uninstalling those components in that order helped the situation.
Welcome to Apple Support Communities!
Best,

I am trying to reinstall iTunes but everytime I try to reinstall it, it is telling me that I can't because I have a newer version of Quicktime installed. The problem is that I cannot uninstall this, please help.

I have just purchased an iPhone 4, but it wasn't connecting to my iTunes, so I took advice and uninstalled iTunes. But when I am trying to reinstall iTunes, it keeps telling me that I cannot because I have a newer version of Quicktime installed. I cannot find this newer version anywhere, and have gotten rid of the Quicktime folder, but it is still refusing to install iTunes.
Please help, I have tried everything.

That's usually caused by damaged QuickTime installation configuration information on the PC.
Unfortunately, this sort of trouble has 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 installing iTunes again. Does the install go through properly now?
(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.)

Can't launch iTunes due to a missing MSVCR90.dll file

iTunes system error. When I try and launch iTunes get the message "The Program can't start because MSVCR90.dll is missing from your computer. Try reinstalling the program to fix this problem." Then it says Error 7 (Windows error 126)
My specs are Win7 64
I had no problems with iTunes since I built this computer 6 months ago. I tried opening iTunes today and poof! it doesn't work.
What I have tried so far: I did a system restore. I uninstalled and reinstalled iTunes multiple times. I did a virus scan: Came back clean. I disabled my firewall settings and uninstalled and reinstalled program and tried to launch. Same error. I did a disk scan on my C drive. I did a registry cleaner with CCleaner. Not sure what else I can do. Any suggestions?

No one else having this problem?

I am trying to update to iTunes 10 to us my new iPad, but I can not remove a corrupted "apple software update" program... I can get everything else off, but due to "previous version" of software update it will not continue.

I am trying to update to iTunes 10 to us my new iPad, but I can not remove a corrupted? "apple software update" program... I can get everything else off, but due to "previous version" of software update it will not continue.
I stopped in to see one of the genius at the local store who referred me to "Windows Installer 4.5 Redistributable" (I am trying to install it on a Windows XP System)
The last version on iTunes on my PC was iTunes 7.
Thanks for your help,

How can I return to the a previous version of itunes?

How can I return to the a previous version of itunes?

The only way to return is to remove Lion and reinstall Snow Leopard.

- it's all said in the title. I can't understand why the developers turn things bad ... risking loosing Apples valuable customers.
More examples needed? (check out the communities and the reviews)
- OSX: Maverick to Yosemite = not recommended (check it out > http://roaringapps.com/apps)
- iPad: older versions as iPad2 should not upgrade to iOS7/8 (it's not supporting its hardware accordingly, it's designed for the latest hardware)
- iTunes (it's possible to rollback to 10.7 - 11.4, but you need to breech OSX system security framework)
- Pages (was a real alternative for many of us, each update reduced features and created incompatibility to older work files)
The list could easily extend to ...

You can offer Apple feedback here: http://www.apple.com/feedback/
as for "
"@Apple, I want a $100 gift card for the inconvenience"
dream on.

From your OLD computer...
Copy your ENTIRE iTunes FOLDER to an External Drive... and then from the External Drive to your New Computer..

I can't open Itunes due to error -45075. What do I do?

I can't open Itunes due to error -45075. What do I do?

I Had this problem along with the error message that it's missing the driver GNSDK_DSP.DLL. I am Windows XP and fixed the error by going to Start>My Computer>Add or Remove Programs
When the Add or Remove programs list is "populated", Find iTunes on it. Click the link that says "For more information" and the iTunes box will expand. You will see a button that says "Repair" and it says to reinstall the program if it is not working correctly, use the "Repair" button. I clicked the Repair button and it automatically started the reinstall. When all the progress bars disappear (it doesn't really give you any other indication that its done) click the "close" button and try to open iTunes again. It worked first time for me. I also saw another forum where someone said it worked for the other Windows versions by following the same route, just that in other windows versions it might be "Computer" instead of "My Computer" and the Add or Remove Programs function is also called something else. Hope this helps somebody having this problem. It drove me crazy finding the answer, but the fix was super simple once I found out what to do.

I updated vietmobile remote files app. this app is broken on iOS 5.1.1 I do not have a backup of the previous version of the (paid) app, how can I roll back to the previous version? Is there a repository of previous versions? Am I boned?

Seems silly to not allow a rollback from a file repository of previous app versions.

>All apps are tied to the account that downloaded it, so to be able to sync back the previous version you would need to still have your copy of that version
I'm not sure I follow, I have not sync'd the ipad with my computer. I just saw an update in the app store and took it.
I tried to del and install the app from the purchased tab in the app store, that reinstalled v2.1 of the app. This also fails to launch.
I have made two service requests to the developer, no response at this time.
Is there somewhere I can download and install Remote Files version 2 file? I can only find the new version 2.1 in the app store.

Problem launching itunes after upgrade to version 7.

launching itunes in another newly created 'administrator' ser name does work. how can i get it to launch with my normal username ? i tried deleting the apple folder in local settings, and application data under my normal username or copy the folder from the new 'administrator' into my normal username, but to no avail yet....
Any help ?

Hi Jason,
I went through the whole msconfig menu and tried to launch itunes but no luck.
Also deleting the file in C:\Documents and Settings\All Users\Application Data\Apple Computer\iTunes\SC Info did not work. After I restarted and launched itunes, box came up stating it was installing itunes, but then it disappeared again. It is still trying to launch and I can see it appearing for one second in the Task Manager if I try to open itunes, but then it disappears and all goes quiet.
I have a Trend Micro Office Scan system operating on my lap top. But then again the 'administrator' user account uses the same settings and can launch itunes....
so the multimilliondollar question is how can I launch itunes within my own user account... Version 6 ran perfectly....

Can't launch iTunes without Quicktime.

I can't launch iTunes. It's telling me I need quicktime 7.5.5. I've uninstalled and reinstalled the latest versions of QT and iTunes and rebooted several times, and I'm still getting the same error message. It was fine 30 mins ago, now it's not working.

'morning.
Try to uninstall your iTunes & reboot then download Quicktime without iTunes http://www.apple.com/quicktime/download/ when installed, (reboot if prompted) & download & install the latest version of iTunes here http://www.apple.com/itunes/download/ .

Ever since the most recent firefox update, every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it?

Every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it? When I restart firefox, then the download continues and all is well until I try to download something new (which I do quite often).

You may well find this article of interest and help in sorting out your problems: [[Installing a previous version of Firefox]] The article does contain a link for previous versions, but also points out other troubleshooting advice that may be more appropriate in some instances.
Another useful article is [[Basic Troubleshooting]]
I hope you sort out your problems either by downgrading or finding the cause of the problem.
