Can't uninstall existing quicktime

I was downloading the iTunes update and it crashed half way through the install and now I can't delete quicktime as it says it's no longer on my computer. However, I can't install quicktime or iTunes now because it says files are missing and that the older version of quicktime cannot be removed. What can I do? I've tried everything, removing the programs, doing a system restore, reinstalling programs and even separate quicktime reinstalls. nothing is working.

You're not alone!! I (stupidly as it turned out)took up the offer of the Update. Result? - no iTunes, no iPod, etc.
I've tried installing the Standalone Quicktime, but it still says some of the files are missing.
You're right. Nothing works. System Restore doesn't sort it either. Where is Apple in all this? There must be millions of us out here. And why can't we totally uninstall?

Yep, there seems to be an issue with this. In addition to getting that error on my iTunes on my PC, I get an error when trying to update apps on my iPhone 5.

Can't Uninstall/Install Quicktime error number: 0x80040707

I am also having probelms with quicktime. I went to uninstall/reinstall it and have had no luck. When I run the uninstall shield, it starts and then before it goes farther than half way loaded it disappears.
I tried everything listed in the post below mine with no luck but I noticed that I have a different error code.
Also, I tried to install the standalone 7.0.4, it installs and then before it completes, when I click finish is comes up with this error:
Error Number: 0x80040707
DLL Function Call Crashed: QT Install code.Quicktimepostinstallproc
Setup will now terminate
I can't do anything with quicktime: run updates or use the plugins: nothing comes up or it restarts my firefox. What do I do? Really appreciate any help, I'm useless technologically. Thanks

hi ChummyGirl!

Can't uninstall Itunes / QuickTime

Hi there,
I upgraded QickTime to v7 and used Mozilla Firefox to find the latest update. It pointed me to a combined QuickTime / Itunes and as I couldn't find a standalone Quicktime Product (have now found), I downloaded and installed. QT didn't run the media as intended so I decided to uninstall and reinstall the standalone product. I can't uninstall either product from the "change / remove programs" as they are not listed. I tried Windows Install Clean Up but no luck there either. The QuickTime uninstaller does not work and Itunes does not show an uninstaller. How do I complete a clean uninstall of Itunes and QuickTime without using "change / remove programs".
Thanks
Howard

Since the uninstall of IT, I am unable to run QT and all Icons have gone from the desktop and the Start menu (menu just has generic Win icons). Uninstall still doesn't work but no nanosecond error? message.
good
b gracious,
Howard ... so the icons from the desktop have
b completely
gone? they haven't just been replaced by generic icons?
there's something going on here that i'm missing ... if anyone else here has experienced anything similar, please feel free to make some contributions.
okay, if the QT isn't showing up in Add/Remove, and Windows Cleanup isn't showing it, and it isn't launching, let's try proceeding with the manual uninstall. (if it does show up in Windows Cleanup now, let's run Cleanup first.)
if it doesn't let you delete anything, let's try to see if there's a rogue QT process still running somewhere and shut that down too. try adapting Katrina's technique to your situation:
Katrina S., "itunes won't open on windows" #21, 01:15pm Sep 3, 2005 CDT
with the QT 7 standalone reinstall:
http://www.apple.com/quicktime/download/standalone.html
... it's best to download and save to the hard drive rather than running the installation on line. given that really odd things have been happening whenever we try to do something, it would be a good idea to shut down all applications running in the background first. there's information on that given here:
http://consumer.installshield.com/kb.asp?id=Q108377
keep us posted.

Can't Uninstall/Install Quicktime...

Basically, I want to uninstall my old version of quicktime. I basically corrupted it (I believe) because it won't open. When I remove the app from my mac, it's no longer there. However, whenever I'm trying to re-install using the official Quicktime 7.6.4 on apple.com - it won't let me. It gives me an error message saying:
"Quicktime can't be installed on this disc. This version of Quicktime 7 can't be installed on the disc because Quicktime X is already present. Please us Software update to install the appropriate version of QuickTime for your mac".
The problem is, when I go to my software update..it doesn't detect that it needs to be updated. So..how am I supposed to fix it? And when I try to open movie files, Quick time isn't even detected as an option (even if I browse). As far as my knowledge..Quicktime is NO LONGER on my mac..yet it insists that it is. I just want to start fresh, I want to be able to re-install it. But it won't let me.
Anyone have any advice for this maddening problem? And just a little more info - (the way i corrupted the file in the first place) - I was trying to install Quicktime Pro 7 and it kept claiming my mac had the newest version. So I removed quicktime completely, and it kept telling me that quicktime (newer version was on my mac, even tho I removed it, even from the Library section) - then I used the Leopard boot up, and used the optional install..and now the file showed back up, but it doesn't have the quicktime logo, (has the application logo) - and it's non responsive. So I deleted that too...but as I said, when I try to install it again from Apple.com..it's a no go.

Can't Uninstall older Quicktime

When trying to upgrade to the new & thats what I get, and then the install quits because iTunes needs Quicktime. I go to Control Panel, find Quicktime, click uninstall, and I windows blinks open and then closed, but Quincktime never uninstalls.
WHAT THE PUCK....IS THIS APPLE TRYING TO MESS WITH WINDOWS PEOPLE.....CAN ANYONE HELP...PLEASE

Arthur, use this program:
http://support.microsoft.com/default.aspx?kbid=290301
to install Quicktime and then try and reinstall, WINDOWS, not apple can be buggy with uninstalls sometimes, but this program should cleanly remove it. It worked for me, some friends of mine, and a person in the Discussions area. Good Luck!

Can't uninstall / delete quicktime

I've been trying to delete quicktime to re-install it and itunes as itunes stopped working ( I couldn't open it at all). a reinstall didn't work, coming up with error code 2330, and when trying to uninstall quicktime it said could not delete zh_CN.lproj. I've tried both uninstalling and manually deleting, and have deleted all except this folder. when I try to open it, it says C drive requires formating (which I can't do without losing all the content). Help! I'd be really grateful if someone more computer literate than me has any ideas. Katie

This error message usually indiactes a corrupt file, try running chkdsk.
You can do this from My computer.
Right click on your C: drive, select properties>>tools>>Error checking.
It starts after a reboot, and takes a while so do it when you don't need access to your PC.
Once you have done that, try a cleanup and reinstall as follows:
Download a fresh copy of iTunes and the stand alone version of Quicktime
http://www.apple.com/quicktime/download/win.html
http://www.apple.com/itunes/download/
Download and install Microsoft Installer cleanup utility, there are instructions on the page as well as the download. Note that what you download is the installer not the program – you have to run it to install the program
http://support.microsoft.com/kb/290301/
Now use the following method to remove iTunes and its components:
http://docs.info.apple.com/article.html?artnum=93698
If you hit a problem with one of the uninstalls don't worry, carry on with the deleting of files and folders as directed in the method.
Restart your PC.
Run the Microsoft Installer Cleanup Utility. (Start > All Programs > Windows Install Clean Up)
Remove any references you find to the programs you removed - strictly speaking you only need to worry about those programs where the uninstall failed.
restart your PC
Install the stand alone Quicktime and check that it works.
If it does, install iTunes.

Can't uninstall old quicktime!!!!!!!!!

HI can anyone help? as i cant uninstall the old qt! ive tried to do the manual way but it just wont do it..???
dell inspiron 6000 Windows Vista

Can someone please help me with uninstalling Quick Time. An error message keeps popping up and will not allow me to uninstall. I was following the directions but when I went to Add/Remove Programs, that's where the error warning appeared. It also wouldn't allow me to delete the Quick Time program file on my Local Disk C.
I have other programs like Microsoft Media and a few others, could these be a problem? This all started when I downloaded an update for iTunes. Two days later everything quit. Can't buy, can't play, library gone and Quick Time will not go away!

ITunes will not launch - can't uninstall Quicktime

I'm really, really annoyed with iTunes.
Rebuilt computer and installed iTunes 7 on a fresh config after antivirus software and firewall were installed. Had sound problems but managed to fix them.
Rebooted and tried to open up iTunes - only to get an error, rebooted again, same thing. Tried opening Quicktime - same. Tried Quicktime settings from control panel - a Fatal error has occured.
Uninstalled iTunes, with an eye to trying to install it again. That worked, but when I tried to uninstall Quicktime it got half way, then "A fatal error has occured". Tried downloading and installing Quicktime without iTunes - that wouldn't even run.
Tried iTunes install anyway, but got the same problems as before. Tried v.6.5 - but that claimed the freshly downloaded file from Apple was corrupt.
I now cannot uninstall or use Quicktime, cannot use iTunes or update my iPods and am really fed up with Apple over this shoddy update.
I've searched through the support pages, but cannot find a fix for this problem.
I'd be happy to try any fixes that might be around, especially if it means I can get v.6.5 on my machine (which worked fine!)
For now, I'm going to be searching out another player for my audio and video.
Most dissapointed.

Tried opening Quicktime - same. Tried Quicktime settings from control panel - a Fatal error has occured.
that corresponds to a "standalone 1603" error message on earlier versions of the itunes and quicktime installers.
let's try this first.
here's what we'll try first.
Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:
Description of the Windows Installer CleanUp Utility
Next, we’ll manually remove leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My 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.
7. Restart your computer.
once we've got all the existing QuickTime scraped away, let's try a careful standalone QT 7.1.3 reinstall.
download and save a copy of the QT 7.1.3 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
Quicktime 7.1.3 Installers … get the one that doesn’t mention itunes
if that install goes through okay, reboot the PC and try another itunes install. does that go through okay this time?
(if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)

Quicktime loaded and not working - Can't uninstall

I have tried for the past few weeks to get my iTunes working.
Everytime I click on iTunes, a message pops up stating that Quicktime Streaming cant run because it is already loaded. I went to Run>MSConfig and turned off the QTTask button, restarted and it still gives me the same message.
I can't open up QT because it shuts down on me when I click any tab in the folder.
I attempted to uninstall and it said the same thing, Quicktime streaming can't run because it is already loaded.
I then went into remove software and tried to uninstall it there and a message came up stating:
Error : 0X80040707
Description : DLL Function call crashed : QTInstall code quicktime.unistallproc.
Setup will now terminate
What does all this mean and how come it's happening? How do I fix it? It was working fine and then just one day, bam, it stopped.

okay, that's a 32-bit version. so here's what we'll try first.
Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:

How does QuickTime 10 go to pro? Can you uninstall it and put QuickTime 7 in it's place?

You can't upgrade QuickTime 10 to pro (yet). Can you uninstall 10 and install QuickTime 7 in OSX 10.6.8 so it can be upgraded to pro?

Can you uninstall 10 and install QuickTime 7 in OSX 10.6.8 so it can be upgraded to pro?
You could, but why bother? QT X and QT 7 Pro can both simultaneously co-exist under Snow Leopard OS. Simply install QT 7.6.6 for OS 10.6.3 and later which is available HERE.

I have quicktime pro and it does NOT have the screen record mode that Quicktime is suppose to have. Can I uninstall it and go back to an older version that would have screen recording? If so, how? Step by step needed. Thank you for your time.

Did you remove Quicktime X?
On a normal install Quicktime 7 is installed in the Utilities folder and Quicktime Pro in the main Applications folder.
You will need to reinstall OS X to get Quicktime X back if you have deleted it.
I notice yor profile says 10.5.8. Quicktime X is only available on 10.6 and above.

ITunes/Quicktime 7.3 upgrade error - can't uninstall previous version..?

While trying to install the new version of iTunes and Quicktime, I get an error while installing:
I checked the folder, and the iTunes.msi file is definitely there.
When I quit the installer, it said to try the Tools > Download Only option in the apple update software. I did it, and opened the iTunes.msi file, and got the same error.
I also tried uninstalling iTunes from Add/Remove Programs, but the same box in the picture above pops up.
Any suggestions?
iPod Shuffle 2nd Generation Windows XP Service Pack 2. Custom built PC. MB: Chaintech 7VJL APOJEE. Chipset: VIA KT333

With those ones try the following procedure:
first, head into your Add/Remove programs and uninstall your QuickTime. if it goes, good. if it doesn't, we'll just attend to it when we attend to itunes.
next, download and install the Windows Installer CleanUp utility. use it to clear any existing itunes and/or QuickTime installation configuration information from the PC.
