Tried to upgrade iTunes, now it's missing from my computer

I tried to upgrade iTunes, but it basically froze. I cancelled the installation with the intention of just trying over. Now, the icon is missing from my desktop. When I go to the program in my computer, it won't start. What do I do to get it up and running again?

How are you getting this itunes update? Through the Apple Software Update program? Or the apple itunes download page?
My advice is to go to the apple itunes download page, choose SAVE to save the entire file to your PC's hard drive, and click the iTunesSetup.exe file after it has entirely downloaded. You don't say your version of WIndows, but it's also a good idea to right-click and choose "Run as Adminstrator" with that setup file.
If you still have trouble with QuickTime, there is also an apple download page for a QuickTime standalone installer.
I always back up my itunes Library.itl database file before upgrading itunes, by the way. I put a copy of it on my little USB stick or one of my exHDs.

Trying to uninstall iTunes but it's missing from programs list

I have iTunes on a laptop with Windows 7 and tried to update but kept getting an error message. I was advised to try uninstalling and then reinstalling iTunes using these steps...
http://support.apple.com/kb/ht1923
However when I go to the list of currently installed programs iTunes isn't there! I can see Apple Device Software and Bonjour etc. but iTunes just isn't there in the list and doesn't come up if I search. It is there when I go to all programs from the start menu and it also runs fine... just wouldn't update!
How do I uninstall it?

I tried to upgrade iTunes, now it won't install on my computer.

I was prompted to upgrade my itunes to the newest version. I downloaded the new version. It downloaded completely but when it came to setup I got a window saying, "The feature you are trying to use is on a network resource that is unavailable. Click OK to try again or enter an alternate path to a folder containing the installation package 'iTunes.msi' in the box below. I have no idea what this is or how to get to it. When I press cancel another window pops up saying the older version of itunes cannot be removed contact technical support group. There is no version of itunes located on my computer anywhere. What do i do to get my itunes back?

"The feature you are trying to use is on a network resource that is unavailable. Click OK to try again or enter an alternate path to a folder containing the installation package 'iTunes.msi'
With that one, let's try the following procedure.
First, head into your "Uninstall a program" control panel and uninstall your QuickTime. If it goes, good. If it doesn't, we'll just attend to it when we attend to iTunes.
Next, download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
Now launch Windows Installer CleanUp ("Start > All Programs > Windows Install Clean Up"), find any iTunes and/or QuickTime entries in the list of programs in CleanUp, select those entries, and click “remove”.
Next, we'll manually remove any leftover iTunes or QuickTime program files:
(1) Open Local Disk (C:) in Computer or whichever disk programs are installed on.
(2) Open the Program Files folder.
(3) Right-click the iTunes folder and select Delete and choose Yes when asked to confirm the deletion.
(4) Right-click the QuickTime folder and select Delete and choose Yes when asked to confirm the deletion. (Note: This folder may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(5) Delete the QuickTime and QuicktimeVR files located in the C:\Windows\system32\ folder. Click Continue if Windows needs confirmation or permission to continue. (Note: These files may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(6) Right-click on the Recycle Bin and on the shortcut menu, click Empty Recycle Bin.
(7) Restart your computer.
Now try another iTunes install. Does it go through properly now?

When I tried to open itunes it told me becuase of this error I needed to reinstall Itunes, my question is do I need to uninstall first before installing and will I lose contents of my library if I uninstall?

Hey Dianna Walker,
Thanks for the question. Yes, you'll want to completely remove iTunes and all related components (it is important to remove all components in the order listed):

itunes error (-42404) -- Okay, getting a little frustrated (but then again, who isn't a little frustrated?). I recently tried to upgrade iTunes software a few days ago but it failed. What is (-42404) error code mean?
I get the following:
(1) iTunes - The software required for communicating with iPods and mobile phones was not installed correctly. Do you want iTunes to try to repair this for you? Yes/No
(2) iTunes - The software required for communicating with iPods and mobile phones could not be repaired. Please reinstall iTunes if you wish to use these devices. OK
(3) iTunes error message - A required iTunes component is not installed. Please repair or reinstall iTunes. (-42404) OK
(4) iTunes error message - We could not complete your iTunes Store request. A required iTunes component is not installed. Please repair or reinstall iTunes. (-42404) There is an error in the iTunes Store. Please try again later. OK
Okay, so I decided to uninstall and reinstall. Funny, iTunes can be found in a program folder, but it does not show up in the programs list. I tried to look for it using the command prompt ("wmic" --> "product get name") but iTunes is not there either. Doesn't even show up in the registry to try to uninstall.
I just want to "properly" uninstall and reinstall iTunes (plus the other usual suspects, Apple Software Update, Apple Mobile Device Support, Bonjour, & Apple Application Support). If anyone out there has any suggestions, please help! (I'm running Windows Vista -- don't judge/laugh) :-)

Okay, feeling like an idiot, but will share so others don't have to. I rebooted my computer and that enabled iTunes to reappear in the programs list. Don't appear to be having the same problems as before (no error messages now). Problem solved!

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. If you're using Vista or 7,now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
To install the utility, doubleclick the msicuu2.exe file you downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Trying to upgrade itunes says it cant find the source file for bonjour or quicktime. so it won't update. any help?

Trying to upgrade itunes. it says it needs the source file to upgrade bonjour and quicktime. I downloaded itunes from a website originally. So therefore, i do not have a "source file" now i try to open itunes and i get a message that says something like "action only valid for installed software. Any ideas? oh ya, and i tried to delete itunes and bonjour and quicktime to start all over but it also said it needs the source files.

Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. (The results from mydigitallife and Major Geeks are worth checking.)
After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes, QuickTime and Bonjour entries and click "Remove".
Restart the PC, and try another iTunes install. Does it go through properly this time?

TS1717 Started a software update this morning which didn't work. Now Itunes will not open at all. I get the following message."The program can't state becasue MSVCR80.dll is missing from your computer."

Started a Itunes software update this morning which didn't work. Now Itunes will not open at all. I get the following message."The program can't state becasue MSVCR80.dll is missing from your computer."

There are a couple of options that I know of to fix the issue.
One is listed in this thread - https://discussions.apple.com/message/24606478#24606478 - and involves uninstalling iTunes and related components and then re-installing iTunes. You will need to read the instructions in the thread to see the correct uninstall order.
Second option is use System Restore to set your system back to a date prior to the iTunes update. I did this before finding the thread mentioned above.
Not sure exactly what the problem is but I know, after a search, that MSVCR80.dll was indeed already installed on my computer.

Hi 49balf,
Thanks for visiting Apple Support Communities.
I recommend removing and reinstalling iTunes using these steps:
Check for .dll files
Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
Reboot your computer.
Note: Depending on your operating system, you may only have one of the listed paths.
Uninstall and reinstall iTunes
Uninstall iTunes and all of its related components.
Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
Re-download and reinstall iTunes 11.1.4.
