error 7 windows error 126

A complete uninstall/reinstall of iTunes and related software components is worth a try (7s can indicate trouble with other software components like Apple Application Support). See the following documents for instructions:

Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7

... But if no joy there, let's check to see if there's a .NET issue underlying this:

iTunes for Windows: "Error 7" message when opening iTunes

update to latest .netframework (see apple support)

Follow the instructions on this link, basically un-install everything, remove programs that says they are made by apple inc. (using add remove program)

You will also need to check and verify that the following folders have been removed:

• C:\Program Files\Bonjour
• C:\Program Files\Common Files\Apple
• C:\Program Files\iTunes
• C:\Program Files\iPod
• C:\Program Files\QuickTime
• C:\Windows\System32\QuickTime
• C:\Windows\System32\QuickTimeVR

dont forget to remove icloud also

you dont need to delete your itune music library though

If any of these folders still exist, delete them along with their contents. (if you cant delete them, right click and go to properties and then security and change the control of the fold to you)

do this for files under program files and program file (x86) on your computer

once you have deleted everything, restart your computer. Then I repaired my registry using a registry repair program.

Important:- instead of installing itunes I installed quick time, which installs apple application support (this is the corrupt file which is causing all the issues)

i then installed itunes and it all worked fine,

should take no longer than half hour to fix 🙂

hope this helps

This worked for me. Thanks

For the latest advice on installation issues see Troubleshooting issues with iTunes for Windows updates.

Amazing! After 4 months (on and off) of dealing with this error, this actually worked.

I had tried just about every other post out there, removed all Apple programs and reinstalled about 7 times, but nothing ever worked. Until i finally came across your post/instructions!

THANK YOU!
