Cannot install iTunes or Quicktime

hello all,
after downloading iTunes i get a dialog box saying "unknow editor, execute?". After saying yes, nothing happens, it's as if i hadn't clicked the installer at all... i tried all the suggestions in the support section, including installing quicktime alone first, for which i still get the same dialog box, and when i click yes, nothing happens...
thanks for your help

Cannot install itunes and quicktime

I get an error message during quicktime installation
"cannot open key: HKEYLOCALMACHINE/Software/Classes/QuicktimePlayerlib.Quicktimeplayerapp/CLSID"
Any suggestions what to do next.

Sounds like something regarding the Quicktime registry files.
Try running through this:
http://docs.info.apple.com/article.html?artnum=302538
Then, go into Control Panel -> Add/Remove Programs
Uninstall anything that says iPod for Windows
Uninstall iTunes
Uninstall Quicktime
If you run into problems uninstalling Quicktime:
Download/install the Windows Installer Cleanup Utility
http://support.microsoft.com/kb/290301
Run it (Start -> All Programs -> Windows Install Clean Up)
Remove anything that says:
iPod for Windows
iTunes
Quicktime
Then, go into C:\Program Files
If there is an iTunes folder, delete it
If there is an iPod folder, open it and delete the folder labeled "bin"
If there is a Quicktime folder, delete it
Then, go to C:\Documents and Settings\yourusername\Local Settings
and delete the 'temp' folder
Note: If you don't see 'local settings' click Tools -> Folder Options; click the view tab; under 'advanced settings' click the option to 'show hidden files and folders' and then click Apply and OK
Empty the recycle bin
Reboot the computer
Go here and download the version of Quicktime that does not include iTunes:
http://www.apple.com/quicktime/download/win.html
Then, go here and download iTunes 7:
http://www.apple.com/itunes/download/
Once you have it successfully installed, you can go back into MSCONFIG and put your computer back to normal startup (just select normal startup, and click apply, close, and restart when it prompts you to)

I cannot install iTunes OR quicktime

I have taken quicktime off of my computer and tried reinstalling it; It didn't let me re-install it. Even from the iTunes website. I have also taken off iTunes and have tried reinstalling iTunes 8. It will not let me. Also. I believe I have Vista 32. And not the 64 bit. I also downloaded a new Java. I've restarted my computer after that like a forum told me so on here. Help would be appreciated!

Hello, Welcome to discussions.
You mention Quicktime and iTunes will not install. Is there any particular messages you are getting that you can post here so we can better assist?
You can check which version of Vista you have by Right clicking on Computer - Properties - In the general tab it will give you info about the OS. Feel free to post the OS info about which version of Vista you have.

Massive problems installing itunes and quicktime

Hi, to anyone who can help me:
I cannot install iTunes or quicktime. Just bought a new ipod 30gb. v.excited. Downloaded itunes. gives me error messages when i try to install.
They read: "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item."
and
"The installation of Quicktime did not complete successfully. ITunes requires Quicktime."
I have tried using CCleaner to clean up my hard drive and uninstall both itunes and quicktime (old and dodgy new versions). I have tried using 7-zip to unpack the new downloaded files and install from the .msi and other .exe files.
I have tried installing the standalone Quicktime (which wont install properly) and then installing itunes (which won't install properly, coz quicktime is not installed properly)
I have tried rebooting my computer between these attempts
I have tried it with my virus-protection software off as one thread here suggested.
I am logged on as administrator for all these attempts and i'm at my wits end.
I have tried everything!
please help me if you have suggestions.
Thanks
Lisa

They read: "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item."
interesting.
did you have an earlier version of itunes and/or quicktime installed on the PC? in particular, an itunes 6.0.x or lower version, and/or a QuickTime 7.1 or lower version?
(checking on this because i'm wondering if there's a DCOM permissions issue involved with the uninstall of your previous versions of itunes/quicktime.)

I cannot install iTunes 10.5. Problem is that there are rest of installations. I uninstalled all iTunes, Quicktime, Bonjour, Apples components, but problem goes on. I run WIN XP SP 3 32 BITS. I accept ideas to solve, thanks.

A bit of repetition, mainly for the benefit of anyone else with the same issue. In your case the "for older video cards" version might be worth a try.
When cleaning folders you need to check both the Program Files and Program Files (x86) folders, which you may well have done but didn't mention in the detail above.
For general advice see Troubleshooting issues with iTunes for Windows updates.
The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if Apple Mobile Device Support won't install normally.
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 performance issues or compatibility with third party software.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

Cannot install iTunes on my Win7Pro PC for several months after a long time w/o problems. Uninstalled iTunes Bonjour with no improvement. Help?

Since October 2011 I cannot update iTunes when I receive an Apple UD notice (Win7Pro PC). I have also lost communication with my iPod Touch. In all cases I have attempted to download the latest version of iTunes. Yeasterday I uninstalled iTunes & Bonjour. I still cannot install iTunes. What can be done to allow iTunes to install?

If you want to do complete reinstall, please follow following steps:
1. Go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes & related installer files:
http://support.microsoft.com/mats/Program_Install_and_Uninstall
Be aware that Windows Installer CleanUp Utility will not remove the actual program from your computer. However, it will remove the installation files so that you can start the installation, upgrade, or uninstall over.
2. You should remove all instances of iTunes and the rest of the components listed below:
it may be necessary to remove all traces of iTunes, QuickTime, and related software components from your computer before reinstalling iTunes.
Use the Control Panel to uninstall iTunes and related software components in the following order:
iTunes
QuickTime
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Follow the instructions from Apple article listed here: http://support.apple.com/kb/HT1923 to remove all components
3. Reboot your computer. Next, download iTunes from here:http://www.apple.com/itunes/download/ and install from scratch

Cannot install itunes on new laptop

Cannot install itunes on new laptop, even when security software is disabled. Downloads fine, goes through install and then says it can't install on my system. I have admin priviledges and already have Quicktime running. Help! I have itunes already running beautifully on 3 other computers and an ipod touch with home sharing - but my new laptop just won't intall itunes. Can anyone help?

Many thanks. Quite often with the 0x800736B3 on the iTunes install, there seems to be an 0x8007000b in play for Windows Update.
Let's try the following document first:
[Windows Update error 8007000b|http://windows.microsoft.com/en-US/windows-vista/Windows-Update-error- 8007000b]
Next head to Windows Update and try stocking back on Windows Updates again. If you're a long way behind (sometimes this has been going on for months for people), you may need to do it in several batches. Basically, keep going back to Windows Update until it stops offering you new updates.
After you're stocked back up on Windows Updates, try another iTunes install. Does it go through properly this time?
(If you can't get Windows Updates to install, post back to let us know the error codes you've been getting on the most recent attempts at updates. Sometimes things are in such a snarl that we have to try a few different measures with them.)

Cannot Install iTune 10.6, always rollin' back

Cannot Install iTune 10.6, always rollin' back

I have problems Installing updates all the time. Its a pain in the butt, but the way I have to install it takes a bit more than anyone elses. First you have to make sure that Any old Itunes files are deleted. The ones that were causing problems for me were
C:\Program Files\Common Files\Apple
C:\ProgramData\Apple
C:\ProgramData\Apple Computer
BUT BEFORE YOU ERASE THOSE FILES FOLLOW THE STEPS BELOW
* You're going to need Winzip or Jzip (Free- http://www.jzip.com)*
STAGE 1:
After you have winzip or jzip go ahead an choose between option 1 or 2:
OPTION 1 (IF YOU'RE UPDATNIG):
1. go to Itunes Menu bar >HELP > CHECK FOR UPDATES
2.error will occur, instructing you to go to TOOLS> DOWNLOAD ONLY
3.Go ahead and Download and save them to your Desktop.
THEN:
Go ahead and uninstall everything in this order.
Using Control Panel\Programs\Programs and Features
iTunes
QuickTime
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Go one by one until everything is uninstalled.
RESTART YOUR COMPUTER
OPTION 2 (IF YOU'RE DOWNLOADING):
1.Go To : http://www.apple.com/itunes/download/ to download iTunesSetup.exe
2. go ahead and open the folder where the file was downloaded to
3. Right Click iTunesSetup.exe
4. Extract the files to your desktop or folder
5. IF you previously had itunes installed you will need to make sure all of these programs are uninstalled in this order
iTunes
QuickTime
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Go one by one until everything is uninstalled.
RESTART YOUR COMPUTER if you previously had itunes installed.
STAGE 2:
Then Go ahead and look for these folders & Delete each one.
C:\Program Files\Common Files\Apple
C:\ProgramData\Apple
C:\ProgramData\Apple Computer
Once that is complete
Go ahead and click on the Itunes installer & install ITUNES
The install will roll back during Apple Mobile Device installation, but should still install.
IN ORDER TO SYNC properly do not stop there.
YOU are going to need Winzip or Jzip (what i recommend) to extract a couple of files.
First file:
Right Click on the APPLE MOBILE DEVICE installer and extract it to a New folder on your DESKTOP.
After you have done so, go ahead and open this folder
Second FIle:
In the Folder you have extracted, you will find a second file named
THIS CONTENTS OF THIS FILE MUST BE EXTRACTED AS WELL!
Extract this file to a NEW folder>>>> NAME THIS FOLDER Mobile Device Support
AND EXTRACT (OR CUT & PASTE) IT TO THIS LOCATION C:\Program Files\Common Files\Apple
Once you have done all of this go ahead and open Itunes
To ensure sync and everything else is working properly.
Hope this helps! in some way.

It will work with Windows 7 32 bit. On a 64 bit you will have to install Windows XP Mode. You can download it from the Microsoft Website. The XP Mode will run Windows XP in 32 bit. Microsoft has easy instructions on the download. One download at a time. Install the first download then the second download. You will have to copy your icon from all program and paste to the desktop if you are going to use it often.
