Thanks to user turingtest2 for this solution.
Solving MSVCR80 issue and Windows iTunes install issues.
If the above doesn’t do the trick entirely, then use the instructions in the following as it applies to the version of Windows you are using:
HT1925: Removing and Reinstalling iTunes for Windows XP
HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8
You may be required to boot into safe mode to complete the folder deletion process.

ITunes was not installed correctly Error 7 (Windows error 998)

HI
I had a Trojan and used Malwarebytes to get rid of it and now everything is fine but for some reason everytime I try to open Itunes I get the message ITunes was not installed correctly Error 7 (Windows error 998)
I have done various searches on this issue and have so far done the following :-
Complete uninstall of Itunes, Quick Time and all associated programs and then a fresh install. I have also updated Microsoft.net framework. I have run a microsoft IE8 repair tool and have also made another windows user account to see if it was just my own user account.
None of this has helped and I am still getting the error. Do I really have to do a complete format on my PC or is there anyone out there that can help?

I've found something that may or may not be relevant.
Whenever I run CCleaner after installing iTunes I get the following registry errors:
Missing TypeLib Reference IUserHelper - {19D52A9A-379C-4720-BA00-3D396ECD24D7} HKCR\Interface\{915DA835-02FE-4953-92FA-624BDF5D85AB}
Missing TypeLib Reference IiPodManagerUI - {19D52A9A-379C-4720-BA00-3D396ECD24D7} HKCR\Interface\{D775A119-EAC2-4F28-B06E-8AC16F2695DA}
These always come back when I try and 'Repair' iTunes from the control panel.
Ideas anyone?

HT1923 After updating Itunes it stopped working. I removed Itunes and reinstalled and i am getting the foloowing errors MSVcr80.dll not found and Itunes not installed correctly error 7 (window errror 126) How do I fix this?

Yesterday I updated my Itunes account and it stopped working. I tried installing itunes version 11.1.4 and once done it came back with 2 error messages MsvCR80.dll was not found and I tunes was not installed correctly Error 7 (windows error 126) I have removed Itunes completely and redownloaded several times with the same result. Is there an easy fix or can I download an older version of Itunes that works?

None of the solutions mentioned in this forum work for me. I've not ever had a problem with your software before. I installed and uninstalled itunes 3 times. No itunes directories exist. I've uninstalled everything labled Apple on my pc withe the same results. The problem is with your software not Windows.

I was cleaning up my laptop to free up disk space, Itunes is now saying itunes was not installed correctly error 7 (windows error 14003) What do I need to do to get my itunes back?

I was cleaning up my laptop to free up some disk space. I now can't get into my itunes ??? It's saying Itunes was not installed correctly error 7 (windows error 14003)
What do I need to re-install to get my itunes back?

Is there also another message, Rob, citing a particular file? If so what is the name of the file? (Precise spelling, please.)
Are you running XP, Vista or 7? (I'm assuming 2000 must have just been a slip of the fingers.)

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 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.

Treloaded. Getting a message "iTunes not installed correctly" Error 7 Windows Error 998. Removed and retried install got same message??????

Trying to install iTunes on my XP machine after the operating system was reloaded. Getting a message "iTunes not installed correctly" Error 7 Windoes Error 998. Removed and retried installgot same message??????

This can sometimes indicate that one of the other itunes-related software components is damaged. (Usually Apple Application Support, but there are other possibilities beyond that.)
Perhaps first try a complete uninstall/reinstall as per the following document:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
Does that get you past the 7?

Updating my Win7 to 12.1, I get 'iTunes was not installed correctly Error 7 (Windows error 127). If I try to launch, I get 'The procedure entry point "CMBlockBufferCopyDataBytes" could not be located in the dynamic link library CoreMedia.dll'. Help!

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.

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.

Itunes will not install correctly Error 7 Windows error 126 Problem is MSVCR 80 not found

Itunes will not install I get a error message ERROR 7 Windows error 126 When I try to open Itunes MSVCR80 Not found

Troubleshooting issues with iTunes for Windows updates

Update to 10.7 did not work, cannot access iTunes. Need AVFoundationCF.dll, Ituneshelper not installed correctly, Error 7 (Windows Error 126), Error 7 (Windows Error 5)

I am running Windows 7 64 bit.
This HORROR began because I realized that my phone had suddenly lost all of the music except music that had been purchased. It also lost all purchased iBooks as well as audible books downloaded from audible and ringtones that I had purchased from iTunes.
I then thought that it would be fine once I connected to itunes on my computer. I connected to itunes and it said that there was an update available so I downloaded and installed 10.7.
I tried to run the program and got Error 7 (Windows error 5) message.
I then found several discussion questions that seemed similar to mine and I think that I tried them all. Removed everything apple and reinstalled iTunes. I followed the instructions and removed everything in the order that was listed, some I had to change security to own the file before I could delete them. I did all of the steps, (maybe I deleted too many apples items ??) emptied the recycling bin, restarted and reinstalled. I also tried the Net framework fix, used the ms fixit (the one with the picture of the man on it) and I think a few other things that I have found on this site as well as MS site. I restarted my computer every time.
The latest thing that I tried was to download 10.63 since I don't care about the new stuff. After all of this I sometimes get and message saying that I am missing AVFoundationCF.dll file and once it said something about Itunes Helper (when these two messages appear, it is separate from the error messages which occur after clicking ok on them) before getting the Error 7 (windows error 5) or else Error 7 (Windows error 126).
PLEASE HELP!

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

ITunes not installed correctly. error 7 windows error 127

I recently updated my iTunes for Mac and ever since then I get an Error 7 (Windows error 127) window after this window (below) pops up.
Any recommendations how to fix it? I've tried uninstalling and reinstalling ALL Apple software, restarting, and it's still giving me that error.

Try deleting the file Webkit.dll from the folder C:\Program Files (x86)\Common Files\Apple Application Support, then repair Apple Application Support in the Programs and Features control panel.
