Why won't itunes install, update or function on a windows pc? two machines, windows 7 sp3

Itunes hasn't functioned for months, I have installed all updates, removed and reinstalled on two different computers. Still crashes on start

'There is a problem with this Windows Installer package.
A program required for this install to complete could not be run. Contact your support personnel or package vendor'.
Perhaps let's first try updating your Apple Software Update.
Launch Apple Software Update ("Start > All Programs > Apple Software Update"). Does it launch and offer you a newer version of Apple Software Update? If so, choose to install just that update to Apple Software Update. (Deselect any other software offered at the same time.)
If the ASU update goes through okay, try another iTunes install. Does it go through without the errors this time?

HT203175 Why won't iTunes install properly? It gives the start up error "The procedure entry point JSStringGetUTF8String could not be located in the dynamic link library WebKit.dll"

I can't get iTunes to install/start on my HP laptop. When I start/install the current version, I get the following error "The procedure entry point "JSStringGetUTF8String could not be located in the dynamic link library WebKit.dll". Why isn't this dll included in the distribution? What do I do to get iTunes to install on my 64-bit AMD HP laptop.

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. Now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair".
Does iTunes launch properly now?
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post:

Why won't iTunes install on my windows xp?

So, my iTunes notified me that I needed to update my iTunes to the latest version. So, I did what I had done a million times before, checked the little box that would install the latest version of iTunes once i clicked the"install 1 item button". After the installation should have been done, my computer said something like, " there was a problem with the installation. please uninstall then reinstall iTunes". I then uninstalled iTunes. Restarted my computer, and went to apple to reinstall iTunes. I ied dozens and dozens of times to install iTunes, and it refuses to install. Why?????????????????

Do you get an error message when you try to install iTunes? If so, what does it say? (Precise text, please.)

Why won't my Safari 5.1.7 launch in Windows XP SP3?

I have spent most of the day today scouring these pages for a solution. I have followed myriad instructions written by B Noir and others. To no avail. Whenever I click the Safari icon, the hourglass appears for a few seconds, but the browser won't launch. Any fresh ideas?

Also, i do not know if it's of interest, but the reinstall did not reinstall AAS. It was there when I followed the initial uninstall phase.
Yeah, that's of interest. If AAS isn't installed, Safari shouldn't launch. (I'm more used to it producing launch error messages, rather than an error-message-free launch error, though.)
Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, does iTunes launch properly now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Why won't my apps update - I have 7 updates waiting to go and when you click on any of the apps, they say installing but have never finished?

Why won't my apps update on my ipad? I have 7 updates waiting to go and when I click on them they all say they are installing but they have never completed their installation? Please help

Try resetting ...
Hold the On/Off Sleep/Wake button and the Home button down at the same time for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings.
You won't lose any data as a result of a reset.

HT1338 Why won't itunes allow me to update my iphone 3gs to ios 5?

Why won't itunes allow me to update my iphone 3gs to a later version?

First, confirm that you really do have an iPhone 3GS and not a 3G:
http://support.apple.com/kb/HT3939
If you really do have a 3GS, make sure you have the latest version of iTunes, 10.7, on your computer.

Why won't iTunes read an RSS file

I have had Radio National podcasts in itunes for a while but it has not updated since Dec 13 and I went to the website to download the new podcasts and it says that I do not have a RSS reader loaded?
Why won't itunes do it?
thanks
Lee

Are you talking about one of these:
http://www.abc.net.au/radionational/podcasts/program/
Click where it says 'Subscribe in iTunes'. When the page opens, click 'View in iTunes'. When iTunes opens and shows the Store page click 'Subscribe'.
If that doesn't answer it, you need to give more details as to what exactly you are doing.

HT2470 Why won't Itunes store my music library in my User/Music Folder, if I select my user name as a storage location in Itunes, Itunes creates folders for artist name right in my user folder, instead of in my user/music folder

Why won't Itunes store my music library in my User/Music Folder?
If I select my user name as a storage location in Itunes, Itunes creates folders for artist name right in my user folder, instead of in my user/music folder. This gets especially annoying because if I tell Itunes to store my "media" in my user/music folder, Itunes will then create a folder named "music" in my "music" folder and will also create additional folders in my user/music folder location to store other non-music media in as well. It is very annoying to see this lack of affinity for folders between two Apple created programs.

Help iTunes locate your media folder:
No content shows up in iTunes after updating

why won't itunes download on my pc. I get an error message saying not a correct 64 bit download???

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 move on to the next item)
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.

Why won't iTunes 11.0.1 sync my Podcasts to my 3rd Gen iPod Touch on IOS 6.0.1?

Why won't iTunes 11.0.1 sync my Podcasts to my 3rd Gen iPod Touch on IOS 6.0.1? I'm running iTunes on my MacBook with Mac OSX 10.6.8. I've checked to make sure in iTunes that the Podcast Sync box is checked and it is. I've tried checking communities and tried several suggestions and nothing seems to work for me. Everything else syncs except Podcasts. I can't figure it out. Any suggestions to get Podcasts syncing to my iPod Touch again? Thanks!

One other step I've tried was removing and completely reinstalling the playlist to the iPod. That cleared up the problem for about two days.
