Cannot install iTunes, Windows 7; error 7

I downloaded the last iTunes update and since then, have not been able to open iTunes. I have followed the instructions from the community posts about uninstalling iTunes and all the ancillary programs several times and still cannot open iTunes. Each time I reinstall, I get an error message about the Apple Mobile Device Support and the install stalls. I cannot get past it. If I hit ignore and let the install finish, I end up with error message iTunes not installed correctly, please reinstall Error 7.
I run Windows 7 on a Toshiba Satellite laptop. All of my Windows updates are current.
Please help. I can't back up my iPhone b/c my settings are for backup on computer. I cannot backup on cloud b/c of this. Because I cannot backup, I have updated my software on the phone yet.
In backup/upgrade limbo.

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.

Cannot Install iTunes Windows 8 after Uninstall

I have a Windows 8 machine with all the updates, and a couple months ago iTunes stopped updating. It was running, but it just would not update. I decided to re-install it, and now I get the error below. I have used Revo Uninstaller to remove every little bit of Apple iWare (including Quicktime and Bonjour), registry keys, and traces, but still cannot install it. Please help, I have searched for weeks through the internet and have tried everything I can trying fix this problem.
Error getting file security:

Thank you!

August 2nd 2013 and still no response from Apple huh? They aren't going to get any further business from me then... this is ridiculous!!!!!!!

I cannot install itunes. The error message telss me I need a CD

I am unable to install itunes 10.5. I am asked for the CD to provide a needed file. I cannot uninstall the prior version of itunes.

Hey sndlot,
Follow the steps in this link to resolve the issue:
iTunes 11.1.4 for Windows: Unable to install or open
http://support.apple.com/kb/TS5376
When you uninstall, the items you uninstall and the order in which you do so arearticularly important:
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.

Cannot install itunes, windows installer package error

I've been looking around for a solution and I still can't find one that is specifically for my case. I've never had itunes before (well I guess I did but THAT never installed for some reason).
Anyways, I can't install the latest itunes (and I tried itunes 9 as well), it keeps giving me this message:
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.
I tried everything! I uninstalled everything and redid the installation. I did this method with the extract.bat to get the msi files to individualling install from the itunes64setup.exe...the only msi files that don't download and give me that error are the updater and actual itunes msi file.
I'm on a:
Acer Aspire 8930G
Windows Vista Home Premium
Service Pack 2
x64 OS

Repair your Apple software update.
Go to START/ALL PROGRAMS/Apple Software Update. If it offers you a newer version of Apple Software Update, do it but Deselect any other software offered at the same time. Once done, try another iTunes install
If you don't find ASU, go to Control Panel:
START/CONTROL PANEL/Programs n Features /highlight ASU and click CHANGE then REPAIR,

Cannot Install iTunes after Update Error Code : -3

When I attempted to update iTunes to version 6.0.5, the iTunes part installs fine and then when the quicktime part is very close to finishing and I get an error saying
QuickTime installation failed:
Error Code : -3
Then, when I try to open iTunes I get an error message saying
QuickTime Unavailable
QuickTime was not found.
Quicktime is required to run iTunes. Please reinstall iTunes.
I have tried installing the standalone Quicktime installer but when i try that it says the the ISScript.msi is outdated and that I need to install the lastest version. I have no idea which one I am supposed to install because there are a lot of different ones.
Any help is appreciated.

Cannot install iTunes - windows installer problem!

I have spent two days trying to fix the registry and use a clean utility. Nothing works! I see that this is a fairly common issue that has been around for several years, but none of the fixes (including the msi utility that MS has now taken down) works. Some suggested that I just uninstall the windows installer utility, but I'm can see how to do that. I've tried stopping the service, but it doesn't work. I am looking at my new iPhone which is a lovely paperweight.

This did not work for me, but you might want to try. I have both an iPhone and an iPad2. I think that I am going to have to reformat my drive.

I have uninstalled and reinstalled a few times but with no luck. Does anyone have another option?

If the above steps haven't helped try installing:
iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)
which is a 64-bit installer for a 32-bit core program, similar to previous 64-bit releases of iTunes.
Or roll back to:
iTunes 12.0.1.26 for Windows (32-bit) - iTunesSetup.exe (2014-10-16)
iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)
as appropriate.

HT1926 Cannot install itunes Error 7, windows error 1114

Cannot instal Itunes, Error 7, window error 1114 ???

Hi!! I finally found a solution
I´m Sure this one will work for everyone
-First you have to uninstall all Apple Software using Control Panel
-Download Unlocker Software from softsonic heres the link http://tinyurl.com/3e8gj2h
or google it
-Install Unlocker
-Go to Start and type this in search: %programdata%
-ProgramData window will open, so find apple folders
-Right click in each apple folder and find Unlocker in the options
-Choose Delete each apple folders (with unlocker program)
-Go to My PC, C Local Disk and find Program Files
-Look for Apple folders and Delete them (with Unlocker)
-Find a Folder (in Program Files) called Common Files
-Delete all Apple Folders (in common files) with Unlocker
- Empty your trash can (thats what i did)
-Reboot
-Install Itunes
Note: You can Reboot or use Safe Mode to use Unlocker if it doesnt work.
....and that's All
AFTER Days of frustration LOL
Good vibe, Love and Blessings for all!!

I cannot install itunes on windows 8.1

I cannot install itunes on my Toshiba Laptop with windows 8.1. I kept getting error 7. So i removed all of the itunes files from my computer, and did everything the install troubleshooting page suggested, but it still will not install, but now instead of error 7, I am getting error 2.

I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

I cannot install itunes on my windown 7 laptop. Error says "computer not modified". Please help me with this problem.

Cannot install iTunes on windows 7 64bit

Okay, I like so many cannot install iTunes on Windows 7 64bit.
Now Orginally I got a message saying something to the effect of:
There was a problem with the install you do not have permission for something...
Through some investigating my iTunes was being installed and removing all my permissions to view and/or modify files within that folder. Even if I was logged in as admin and installed as admin all the permissions would simply block me out.
This kind of had a familar feeling as in the last few versions of iTunes I had to run as admin just to open it (this is really annoying by the way)
So I searched the net and many people were saying to uninstall everything "Apple" and try again. So I did that. Now I have this new message:
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.
And again I scoured the internet for a way to fix this. I apparently am supposed to goto Control Pannel/Programs and Features and select Apple Software Update and select repair. The problem is that no longer exists in my programs list since I removed it in the earlier step. iTunes still refuses to install spitting out the same error forever. I tried the Microsoft "fix it" tool which is supposed to remove the Apple Software Update incomplete uninstall (which is apparently the whole problem) but it doesn't show up in the list for "fixing".
I am at a loss. Why doesn't Apple fix this. I cannot update my iPhone to the latest software in fear I may need to restore it. With no iTunes that is impossible. I cannot change any of my music or do anything until this is resolved. If/when iPhone 5 comes out I cannot get it either unless this issue is taken care of somhow.
I searched for an installer for just the Apple Software Update program But it seems to not exist as a standalone thing (it would be useful if it were though). If it were perhaps I could install it again and then successfully remove/repair it and iTunes might install finally.
Now I have had previous versions of iTunes working perfectly fine. I do not recall which version I was using before I tried to update and fell into this abyss however.

Yes b noir. I've tried running just "iTunes64.msi" from the command-line and while it didn't produce the 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 vender." it produced a different error in bold-type "iTunes Installer Completed" then "The installer encountered errors before iTunes could be configured...Errors occurred during installation. Your system has not been modified...Please run the installer again, or click Finish to exit". However, I discovered a wealth of options from the Windows Installer to try after typing "iTunes64.msi passive"...So I'll experiment some more when I have time.
P.S. I'm becoming more convinced that Apple is putting new software out there to get it debugged which was a trick that MicroSoft always seemed to do:-)

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.
Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?
If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? (For example, 8007000B.)
