ITunes not working and not installing.

So at first i was just trying to update my iTunes but after many failed attempts i consulted the support page and went through the troubleshooting process and none of them worked so then i uninstalled iTunes from my computer but it will not let me reinstall it. any ideas as to why this happening?

Service 'Apple Mobile Device' (Apple Mobile Device) failed to start. verify that you have sufficient priviliges to start system services. then it gives the options of abort retry or ignore; when i hit retry or ignore it just goes back to the same original message
Many thanks.

All of a sudden my iTunes stopped working, and I get the following error messages:
1. the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem
and
2. iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 126).
Now I've checked the forums and followed the advice of uninstalling all Apple applications, rebooting, and reinstalling iTunes.
This is not working. I've tried installing as Administrator but doesn't make any difference at all.
There must be a way to fix this? I'm not a tech geek but I want to avoid having to take my laptop back to factory settings to sort this out.
Thanks

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.

Itunes not Installed Properly, Repaired and no luck.

Hi. I haven't been able to create a CD for about 2 years now. I searched through these forums and found other ways of Repairing the Itunes program and have had no luck. I've repaired through downloading Itunes again, when Menu pops up, I choose to Repair ( too afraid to uninstall, and lose data). That finishes and I re-open Itunes, and still receive the same message ( Itunes not installed properly, you cannot burn/import a CD). I saw on a post on this forum about repairing it through my Windows Control Program ( Add / Remove) - did that, thought it worked out but did not. Do I need to restart my computer for changes to occur ? I also ran the itunes Diagnostics and these are my results.
Also, I see that it states I'm not the Adminstrator..... I am ?

Hello Craz4Sk8erGuy
If you uninstall iTunes, you will not lose any data if you uninstall iTunes, the iTunes database file will not be removed. Check out the article below on how to completely uninstall iTunes and its associating services. Also, I found an article for burning issues with Sony burners as well.

Why is my itunes not installing properly? I installed it and it was fine, then it started to show Errors. iTunes exe - Entry Point not Found. And the Error 7 (Windows error 127).Itsays to reinstall iTunes. I did that and same error. new pc, same on old

Why is my itunes not installing properly?
I installed itunes day before yesterday, I spent hours last night linking all my music photograph and movie files, its a new windows 8 laptop.
I plugged in my 64GB ipad 3 rebooted it and reloaded all the information I wanted on it, took hours... finally completed this this morning. After this I restarted the laptop to configure my icloud link for the laptop (which I installed last night while I was loading files, I chose to restart later)
on completion I turned my laptop off for a few hours, when I turned it back on I went to itunes to connect my iphone to do the same and I got this message:
iTunes exe - Entry Point Not Found
The procedure entry point
AVCFPlayerAppliesMediaSelectionCriteriaAutomaticallyKey could not

then after pressing 'OK' the following message:
iTunes
iTunes was not installed correctly. Please reinstall iTunes
Error 7 (Windows error 127)
I went back to apple website to reinstall iTunes, first reinstalled it same again, then unsinstalled it and the reinstalled it, same again.
The same thing happened with my old lap top and I replaced it with this new one at the start of the week.
Has anyone any idea what is going on and how to rectify this problem, I am now going on 3 weeks without iTunes.

I started up and plugged in my iPad and then the following message came up:
       iTunes
❗️This iPad cannot be used because the required software is not
    Installed. Run the iTunes installer to remove iTunes, then install

I then proceeded to the "iTunes64Setup" expanded folder to load "AppleMobileDeviceSupport64"
Started the install and then received this message:

I tried all tree options, last being ignore.
I continued to download the other 2 you suggested with out any drama.
I did a system restart and then opened iTunes.
Connected my iPad
Then message appears:

Press OK and then the next message:

Any suggestions?

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?

First try updating to iTunes 11.1.5.5, using an installer downloaded from the Apple website:

10.5 will not let me add album name. itunes stops working and shuts down

10.5 will not let me add album name. itunes stops working and shuts down.

I am having this problem. At first with the new iPhone 5, and then with the iPad 2. I am not sure why this is happening.
My gut feeling is this is an iO6 issue and here's why -
The problem mainly occurs with apps. I have about 150 apps, and when I plugged in the phone, iTunes went to sync all of them. The process would hang up after about 20 - 30 apps were loaded onto the phone. I could tell where about the process hung up because the apps on the phone showed up as "waiting".
Then on the iPad 2 I plugged in to sync and saw there was a huge "Other" component in my storage. It required me to restore the iPad 2 from backup. With this restore the same issues occurred - putting the apps back on the iPad would hang up. The videos on the iPad also got stuck - maybe after about 10 hours of videos transfered iTunes crashed.
My solution has been to soft reset the device, restart Windows, and continue the process until it's complete. This is remarkably inefficient and time-intensive but everything works with patience.
I have been wondering if others have had these same problems.

Itunes not installed correctly error even though install is successful

I installed Itunes 9 and was working fine. All of a sudden i started getting errors saying "Itunes not installed correctly. Please reinstall Itunes" Error 7 keeps coming.
I reinstalled and installed several times. Finally i removed all apple software in the order of itunes, quicktime player, and other apple software. I reinstall and still keeps saying "Not installed corectly". I have windows xp professional.
I'm pulling my hair

Have you give the complete error message?
Some people have had error 7 when there is a problem with Apple Application support.
Did you remove that when you did your uninstalls?

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 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.
