Help: Can't Unstall Quicktime

Trying to uninstall Quicktime so I can install iTunes 7. The installation of inTunes 7 has been stalling because it says it cannot uninstall an older verion of Quicktime.
Steps taken thus far:
1. Done add/remove of Quicktime (though it doesn't remove the Quicktime image)
2. Deleted Quicktime and iTunes folders from Programs and from Windows/System32
3. Done "search" for all things Quicktime and deleted any file named Quicktime.
Nonetheless, still get the message: An older version of Quicktime cannot be removed.
Help! What am I missing to uninstall this program so I an move forward with iTunes?
Thanks in advance.

okay, there may still be corrupt QT installation
configuration information on the PC.
Download and install the Windows Installer CleanUp
utility. then use it to clear any existing
QuickTime installation configuration
information from your PC:
Descrip
tion of the Windows Installer CleanUp Utility
after removing the QT installation configuration
information, restart the PC and try another iTunes
install. does it go through properly this time?
I got this nasty error after I cloned my old hard drive to a newer big one and tried to update iTunes. I have been battling this problem for over a week. Here is what I have done so far and I still can't get it to install
1) Uninstalled all apple products (including iTunes)
2) Deleted all quicktime values from the system registry using regedit. This took forever because I went back and got all QT related values such as QTUtility mentions.
3) Used the Windows Installer Cleanup Utility.
4) Downloaded an older version of QuickTime.
None of this worked, as I still got the same error. Here is what finally fixed my problem:
1) Deleted all files in C:\windows\temp.
Save yourself some time if you get this error and delete your temp folder first

Can't open quicktime movie that I exported from FCP 5. Help!

What arrow?
Have you tried opening the file in FCP?
If there is no error message and it will not play in QT7, it is quite possible the file is corrupted. You will need to go back to the original project and re-export the file.

I can't download Quicktime Pro? HELP!! I have Quicktime viewer 7.5 and just bought the download for Quicktime Pro upgrade.
But the "Control Panel" window they tell me to look for can't be found. All I can do is open my Quicktime Player 7.5 window, and it doesn't offer the tabs in the instructions.

HELP! - can't uninstall Quicktime!! Error - 0x80040707 !!

I can't uninstall quicktime and get the following error -
Error 0x80040707 Description DLL function call crashed QTInstallCode.QuickTimeUnInstallProc
Can anyone help??

hiya!
okay, in this context the 0x80040707 (citing the QuickTimeUnInstallProc) usually indicates that the installation configuration information for the QT on your PC has been corrupted.
download and install the Windows Installer Cleanup utility, and use it to clear away any existing QuickTime installation configuration information:
Description of the Windows Installer CleanUp Utility
... and then use the QuickTime component of the complete uninstall instructions on the following document as a guide for manual removal of left-over QT program files and folders:
Trouble installing iPod, iTunes, or QuickTime software in Windows
once we've got the old QT scraped out of there, we'll try another standalone QT 7.0.4 install, taking a few additional explicit precautions.
download and save a copy of the standalone QT installer to your hard drive. (we'll run the install from there rather than online.) switch off all antivirus and antispyware applications prior to the install.
Quicktime 7.0.4 Standalone Installer
does that install go through okay?
if it does go through okay, does your itunes launch again?

Please help: Can't download itunes with windows 7 (64 bit). Keeps freezing at 99%

I have tried deleting and re-installing itunes and quicktime but it still won't work. Please help.

Can someone please respond to my request for support? I tried the provided correct answer at https://discussions.apple.com/message/11561783#11561783 but it did not work.
I also got a MSFT tech support person to remotely look at my machine, for what its worth, he said the registry file is fine and to contact Apple support.
Any help would be very much appreciated.

That's a peculiar one to get in the context of a QuickTime uninstall.
Which particular version of QuickTime for Windows are you currently running? (7.7.5, 7.7.4, something earlier?)

Can't install iTunes 6.0.2.23 and can't uninstall QuickTime

HELP!!! this is driving me crazy...does anybody know how to fix this problem. how do i uninstall old version of QT in order to upgrade to the stand alone QuickTime and newest version of iTunes? I've already tried to manually delete the QT files and folders but got an error message. This totally *****! Both Apple & Windows support are pointing to each other for fixes.

How can I get QuickTime to install

I am not computer person. All I am is a mom who wants her kids ipods to work. I can not get QuickTime to install or uninstall so that I can use itunes. I updated Windows and I tried several other things but I just can not get it to work. Help me!!!!!!!!

I finally got the quicktime to download and I also downloaded itunes but it won't work right. When I click on the icon to pull it up so that it will recogize my ipod it tells me it has a error for me to check with microsoft. I had a shuffle at one time that worked and when you plug your unit in it should take you to your playlist and things put it doesn't do that it just tells me I have a error.

How can i get quicktime to work on my windows vista

everytime i download the latest update of quicktime, it says it cannot find the "active x control" can someone explain to me what that is, and how can i get quicktime working so i can have my iTunes running again

I was just on a windows computer with some horsepower power. I can't get it, the video would play fine, but no audio. Perhaps Jon could take a look? I can't pick up anything on it, other than it's a .mov
I no longer have home access to a Windows machine or Mac running Windows OS. As I am not an HTML programmer, I did not check the page coding but had no problem playing any of the video content on the linked page using the Safari browser. Spot checked the source files and found them to be typical MPEG-4 AVC (H.264) files with a frame rate of 30 fps using CABAC entropy Main Profile Level 3.0 (SD) and Level 3.1 (HD) encodings in MOV file containers. As to audio, only one file—Video+(1).MOV (the "Raven, Salma and Kenneth" Claymation Practice file)—contained an AAC (LC) audio track. Except for the use of capitalized extensions (which I don't think should cause a problem), the videos themselves look standard and should be playable on any system using any compatible media or plug-in players that support standard MPEG-4 content and the MOV file container.
Sorry I couldn't help more.

I need help to re set QuickTime player as my default internet Video Player

Does anyone know about QuickTime Player 7 10.0?
I have a Real Player software Program that is set as my internet default video player, I want to change and re set my internet video player as my default QuickTime Player, I don't know how to change and re set my Internet Video player. I noticed that in my QuickTime Player it doesn't have a preferences under the quickTime Player Menu. Does anyone know how I can re set My QuickTime Player as my internet Video default Player?
Thank You,
Mrs. Trisha Foster

Sorry, look under the Help menu -> installed plugins (I'm using Firefox and had to keep showing/hiding Safari). As for the other location, don't change anything there (not good to change anything in the Library folders) - I just wanted you to look to see if Quicktime is there or not. If it is, you need to take a look while Real Player is open to see if it can be disabled - I don't have it, so I can't give you instructions. If you can't find Quicktime in either location, there is something strange going on because it should be.
If you can't find it under plugins, also check in Applications to see if Quicktime Player is installed and post back. Also, do a search for Quicktime and Quicktime plugins.
I am not sure if you can just download and install it from the Apple download site or if you'd need to use your install disk to reinstall it from there; if you do not have it installed anywhere, it should be fine to download it - hopefully someone else will be able to confirm this.

Can't install Quicktime - Error "A newer version of quicktime already..."

Hi, I have a Dell XPS running Windows Xp Media edition. Quicktime files would not play so I downloaded the newest version of Quicktime and an error comes up saying, "A newer version of quicktime is already installed. This installation of Quicktime can not proceed while the newer version is installed." I can't find a newer version on the computer and the application seems absent. Only suplimentary Quicktime files are found. Please help.
Thanks,
Eric
Dell XPS Windows XP

I'm having this exact same problem. I have a Gateway running Windows XP Media Edition.
I can't run quicktime, it says it's not there. I've tried uninstalling using add/remove and it says the uninstall.log file is missing. I tried uninstalling using the QT uninstaller option in its folder, it says the uninstall.log is not there. I tried 'repair' option on the iTunes+QT installer that I downloaded. Still the same issue.
I tried the stand alone QuickTime installer and it tells me "A newer version of quicktime already exists".
I tried deleting the residual quicktime folders from my c:\program files. I tried deleting the residual QT references from my regedit. I downloaded the MS Windows Install Clean Up and looked in there--found 2 more things that could possibly be quicktime related and removed those. I tried again -- same error message.
I'm not sure what else to do. I'd really like to get Quicktime and iTunes working by Christmas so I can sync my shiney new iPod.

Can't install Quicktime 7 as won't uninstall Quicktime 6.5

Hi
Trying to install i-tunes with the new version of quicktime but when it tries to uninstall my current version of quicktime (6.5) the following message appears:
Could not open key:
HKEYLOCALMACHINE\SOFTWARE\Microsoft\windows\current version\uninstall\quicktime. Verify that you have sufficient access to that key, or contact your support personnel.
How can i uninstall quicktime 6.5 & install the new version? What is a HKEY?
i have contacted both itunes support and pcworld support to no avail. Can anyone HELP, PLEASE!!!
Thanks

I spoke too soon on that one. Tried everything listed in the certificate to no avail.
6.5 version never did work on that PC. XP SP2, nothing special.
It cannot go on line either. Lightning made sure of that.
I deleted any version trace of it on the PC, Then several attempts of getting the right version for XP.
Download it to a memory card on This Apple Laptop.
Then over to the PC to install.
After the 3rd try with finally the correct version of 7.1.6, we have success.
A bit tough to find a version that worked. You don't know until the version is tried.
There was no direct path searching for 6.5 of what it had and to what came next.
No Guru God here.
Just trying different sockets from the mixed up tray of choices to set the record straight.
