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?

I have the same problem and
have followed the link uninstalling in the correct order,
then restarted as per instructions,
went to Apple to download itunes,
hit download now,
Visit the iTunes download page. Click Download Now to download the iTunes installer. When prompted, click Save (instead of Run).
did not get a save instead of run prompt
Right click on iTunesSetup or iTunes64Setup (the installer you downloaded in step 3).
If you have Windows Vista, Windows 7, and Windows 8: Choose "Run as administrator."
i can only click run as administrator from right clicking the shortcut on my desktop screen
If iTunes fails to install or repair, it might be necessary to remove components left from a previous installation of iTunes and then reinstall.
sick of doing this

Service 'Apple Mobile Device' (Apple Mobile Device) failed to start. Verify that you have sufficient privileges to start system services. and 'iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 193)

Hi!
So i think i closed the wrong service at some point a few weeks back (apple mobile device) but iTunes remained working after that for another week. I then updated iTunes and i get the same "Service ‘Apple Mobile Device’ (Apple Mobile Device) failed to start. Verify that you have sufficient privileges to start system services." every time. If i click ignore, just so i can access iTunes with out syncing my iPod (touch 2nd gen) i then get 'iTunes was not installed correctly. Please re-install iTunes. Error 7 (Windows error 193)" when it has all installed. I don't understand what the problem is anymore as I have looked at other questions on the apple website, carried out the advice and it hasn't work. Any of them.
Tings I have done:
- Wiped all iTunes and Apple data from my computer (if you search for 'iTunes' or 'Apple' nothing comes up apart from applets from system code.
- Attached iPod before iTunes install and updated drivers.
- Installed iTunes as 'Run as administrator'
- Uninstalled and re-installed the software nearly 20 times now and rebooted the computer in between everytime.
Please someone help because i really need to get music on my ipod and i enjoy the ease of use of iTunes compared to spotify or Windows Media Player.

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 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.
Regarding AMDS failures there is a hint in another thread that disabling the Windows Firewall before attempting to reinstall may help, otherwise take a look at the steps outlined in this post. Re: Can't install iTunes 12.1 on Windows 7 64-bit. I know they look a little daunting, but the process of generating the logs themselves isn't that hard to do. Extracting useful information from them is still a challenge but maybe something will leap out. If you want to post the log for the failed components for me to have a look at here or in the other thread please edit out any personal information, particularly your email address, first.

When opening iTunes 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, reinstalled many times - nothing! help please.

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.

HT1926 Have the same problem as many other users: tried to update iTunes on Windows 7 today; first message "unable to locate component- MSVCR80.dll was not found" then "iTunes was not installed correctly. Please reinstall iTunes - Error 7 (Windows error 1

I have the same problem as many other users: updated iTunes on Windows 7 on Jan 26, 2014 and iTunes does not open. First message "unable to locate component- MSVCR80.dll was not found" then "iTunes was not installed correctly. Please reinstall iTunes - Error 7 (Windows error 126)". When will Apple fix this? Don’t feel like uninstalling all Apple software and then re-installing it as suggested, as I am on a terribly slow internet connection while travelling in the DR Congo.

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.

Troubleshooting issues with iTunes for Windows updates

ITunes stopped working on Windows 8. Error message 7: iTunes was not installed correctly.

I have Windows 8. Originally iTunes worked fine, then it couldn't update (said it was unsuccessful). Then it stopped working, so I (after much research) tried a long and tiresome method of removing all Apple products and re-installing them. I did this 3 times and it eventually worked and has been working fine for a few months. Recently, when trying to update, it has said "update successful", but when checking for new updates, finds the same one it supposedly just installed, wanting to install it again. For a few weeks now it has not worked at all, saying "error message 7: iTunes was not installed correctly" when I attempt to open iTunes. I can't bring myself to go through the whole process again of uninstalling and reinstalling everything, it took hours and it clearly doesn't solve the problem. I have no idea what the problem is. Reinstalling only iTunes doesn't work. The support pages have no advice available for my crappy version of Windows.
Please help me!

iTunes update 11.1.4 produces an error message R6034 "An applicaton has made an attempt to load the C runtime library incorrectly" When that error is acknowledged, a second windows error 1114 "error 7" displays "iTunes was not installed correctly". I also tried to downloadiTunes 11.1.4 at th Apple website and that did not work either-It stalled with an erro message that stated the "mobile service" would not open HELP!

Hi Doug! I was having the same problem but after reading a lot of answers I found the solution. First of all you need unistall ALL THE SOFTWARE OF APPLE from your computer, I mean BONJOUR, QUICKTIME, ITUNES, APPLE SOFTWARE UPDATE, APPLE MOBILE DEVICE SUPPORT and the other one that is from compatibility with apps of apple, after that you must verify if this folders are removed if they don't then remove it:
C:\Program Files\Bonjour
C:\Program Files\Common Files\Apple\
C:\Program Files\iTunes\
C:\Program Files\iPod\
If you have a 64-bit version of Windows, you'll need to confirm that the following folders have been removed:
C:\Program Files (x86)\Bonjour
C:\Program Files (x86)\Common Files\Apple\
C:\Program Files (x86)\iTunes\
C:\Program Files (x86)\iPod\
Then if you have ccleaner you can use it to clean all registers left, then reboot and try to install iTunes 11.1.4 again as administrator... That works for me, I hope that helps you too...

Has anyone ever received the error Itunes was not installed correctly. Please reinstall Itunes Error 7 Windows error 126

I had to reinstall my Itunes account and after installing received this error: This application has failed to start because MSVCR80.dll was not found. Reinstalling the application may fix the problem.
The other error message that displayed after I tried to reinstall it was "Itunes was not installed correctly. Please reinstall Itunes Error 7 (Windows error 126).
Any assistance with correcting this matter is greatly appreciated. My ipod is fine, I just need to reinstall Itunes on my computer.
Thanks,

There has been a lot of that lately, try following the instructions of tt2 in https://discussions.apple.com/thread/5822086 to fix it.

I was today invited to upgrade my iTunes when I logged on. Update failed. Every time I now try to open iTunes I get error messages. Second message reads "iTunes was not installed correctly. Please re-install iTunes. Error 7. Windows error 126"

I was today invited to upgrade my iTunes when I logged on. Update failed. Every time I now try to open iTunes I get error messages. Second message reads "iTunes was not installed correctly. Please re-install iTunes. Error 7. Windows error 126". I now can't sync my iPhoneand I am worried that if I re-install I will lose all my contacts,calendar, notes, etc.

I too had this problems (Windows 8.1). A few weeks ago after the previous update before this version of itunes, I'd had a problem with the itunes store crashing and at that time I followed instructions to copy QTMovieWin.dll to the itunes folder, which fixed the store crashing.
Today I fixed the problem by:
Delete QTMovieWin.dll from C:\Program Files (x86)\iTunes.
Uninstall ALL Apple Software using Control Panel / Programs and Features. I uninstalled:
iTunes
QuickTime
Apple Mobile Device Support
Apple Application Support
Apple Software Update
Bonjour
Delete the folders:
C:\Program Files (x86)\iTunes
C:\Program Files (x86)\Common Files\Apple
Restart the computer
Reinstall QuickTime
Reinstall iTunes
Everything works GREAT now, including the iTunes store. You will not lose your media files, I got everything back, all my settings, playlists, etc.
