HELP! Error 7 (Windows error 127) - iTunes was not installed correctly.
I have now had this issue for several months now. I have tried on numerous occasions uninstalling all iTunes files and then downloading iTunes again and again and again only to get the same error message over and over. Can someone please help me? I'm missing my music terribly and am sick of iHeart Radio!

My Toshiba laptop just recently started showing the the following error message when I try to open iTunes: " iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 998)". I did what was requested and reinstalled iTunes, but still get this error message. Help!
b noir I never got any message about an entry point
Many thanks. If we're looking at a "naked" Error 7, I'd start with box two in the following user tip:

I have the latest version of iTunes and when I went to go open it, it can't! It says: "iTunes was not installed correctly. Please reinstall iTunes.Error 7 (Windows error 126)" What do I do now? Should I uninstall and try installing it again? I don't want to loose any of my music and info. PLEASE HELP!
Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

Whenever i open itunes after installation it says error 7 itunes was not installed correctly

For general advice see Troubleshooting issues with iTunes for Windows updates.
The section Install missing components may allow you to install Apple Application Support.
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.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If the advice above doesn't resolve things you could try this alternate version:
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 the 32-bit version of the core application, similar to previous 64-bit releases.
Or roll back to the previous build:
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)

Was not enough room to finish. I tried to uninstall all Apple programs and reinstall but I was asked to validate an unidentified publisher and don't have a clue what that is and could not remove programs. I am not good at fixing stuff on the computer and would like some help with this. I have had iTunes for a long time without issue.
Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall press on)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

following an update of itunes I keep getting the messageI "Please reinstall itunes. error 7 (windows error 5)." I Have uninstalled and reinstalled Itunes 10.7.0.21 and keep getting the same error message.
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 -
Windows version 7. Auto update of iTunes to version 12.1 from 12.0.1.
At end of install process, message 'iTunes was not installed correctly. Error 7 (Windows error 127).
Tried to launch iTunes, anyway, but immediately got message 'The procedure entry point "CMBlockBufferCopyDataBytes" could not be located in the dynamic link library CoreMedia.dll'.
Tried downloading iTunes and updating manually - get exactly the same result.
No problem using iTunes before this.For general advice see Troubleshooting issues with iTunes for Windows updates.

The error hints at a similar pattern to those discussed in the first and third boxes of the user tip, suggesting that you've got an outdated .dll file that needs replacing. You should find CoreMedia.dll in the one of the following folders:
C:\Program Files\Common Files\Apple\Mobile Device Support
C:\Program Files (x86)\Common Files\Apple\Mobile Device Support
Delete it and then repair Apple Mobile Device Support from the Programs and Features control panel. If that doesn't work go for the full tear down and rebuild.

I tried to update iTunes to version 10.5.2 and now I can't open it. After it said it was successfully downloaded, it tried to open iTunes and it said iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 127). I unsitalled iTunes and tried again, and nothing works. Help.
Doublechecking first:
I unsitalled iTunes and tried again, and nothing works
Where you using the following document as a guide for that? (The 7 can be produced by damage to the related software components, so the Verify iTunes and related components are uninstalled step is quite important.)

When opening iTunes on my new Windows 7 PC I continue to get the same messages, 'The program can't start because AVFoundationCF.dll is missing' and 'iTunes was not installed correctly. Error 7 (Windows error 126)' I've uninstalled and reinstalled many times to no avail, even tried it on a different user account and still nothing. I recently installed Panda Internet Security 2012 (about 12 days ago), initially iTunes worked fine as usual but within the last few days I've been unable to open it with the same messages appearing. I've read through some of these pages and tried everything that's been advised, uninstalling and reinstalling while internet and laptop security is swithched off, downloading tools to completely remove anything related to iTunes, tried it in Safe Mode, nothing has worked. I've also noticed that in the start menu when I click on iTunes, it says '(empty)' where it should have the logo and ability to start the program, does this mean it doesn't download + install properly each time I've tried? Any help would be enormously appreciated.

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) (not for XP) 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.

iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 5). I have uninstalled in correct order and reinstalled but still getting same error message. Any help??
Take a look at iTunes for Windows: "Error 7" message when opening iTunes. Perhaps your .NET Framework needs a repair.
