ITunes will not open on my Windows 7 computer. I've uninstalled it and reinstalled it, but it still won't open?

iTunes will not open on my Windows 7 computer. I've uninstalled it and reinstalled it, but it still won't open. I'm trying to synch my iPad and iPhone, which I haven't done for awhile, but right now I'm having no luck. I'm sure there is a switch I need to turn on or off, but have no idea where to find it. Can someone help?

In the course of your troubleshooting to date, have you worked through the following document?

Doublechecking. Did you just uninstall iTunes, and not the related software and components?
The 7 can be caused by damage to one of the other software components associated with iTunes (most commonly Apple Application Support). If that's what is afoot, a complete uninstall/reinstall may be of some assistance:

My iTunes suddenly stopped working. I uninstalled it and reinstalled it twice. It gives me an Error message 7 or windows error message 126. Any ideas of why this is happening?

Try removing and then reinstalling the Apple software using these instructions.

The above containes a link for XP. Also. make sure you install the correct Apple software, It comes in 32 and 64 bit and you need the one that is the same as the computer OS

I had this problem as well but found the soultion on another post from turingtest2 - it worked for me:
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
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or by right-clicking the downloaded installer and selectingRun as Administrator.

Hi braddyloopy,
Thanks for visiting Apple Support Communities.
If you need to uninstall and reinstall iTunes, your music files should not be erased or affected in any way. It is always a good idea to back up your data before making any changes to your computer, though.
If you'd like to locate your music, this article explains how to find the files:
Where are my iTunes files located?

When you reinstall iTunes, I'd recommend using the method in this article to make sure it's reinstalled completely:

Hy won't my ipod touch 5G connect to my computer or itunes? I've tried new USB cables, different USB ports and uninstalling itunes and reinstalling.

Why won't my ipod touch 5G connect to my computer or itunes? I've tried new USB cables, different USB ports and uninstalling itunes and reinstalling.

See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:
iOS: Device not recognized in iTunes for Windows
paying special attention to item #5
- New cable and different USB port
- Run this and see if the results help with determine the cause

I plug my ipod into my computer itunes pops up with error message "Ipod detected but can't be identified properly" suggests I unplug and try again or uninstall itunes and reinstall nothing works. What should i do?

I plug my ipod into my computer itunes pops up with error message "Ipod detected but can't be identified properly" suggests I unplug and try again or uninstall itunes and reinstall nothing works. What should i do?

summarizing:
iPod nano (what version iOS BEFORE update?)
downloaded music
updated iPod to iOS 8.1.2
Windows 7 PC
plug-in iPod to PC
error message from iTunes on the PC "Ipod detected but can't be identified properly" ⬅[quoted from your original post] (+ suggested troubleshooting steps)
un-plug > re-plug iPod (how many times?)
iTunes un-installed from PC (?)
iTunes RE-installed to PC (?)
error message repeats(?)
searched "Ipod detected but can't be identified properly" site:support.apple.com with ZERO results - pretty strange that the support site wouldn;t know an iTunes generated error message (?) EDIT - had an "aha! moment when using a fresh Google search page and 'suggested' CANNOT
then "Ipod detected but can't be identified properly" site:discussions.apple.com had ONE result = Can't connect to iTunes with ipod touch (-50 error) - NO REPLIES
CANNOT instead of can't [ tsk tsk ]
iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support
follow all the instructions in order and let us know

Firefox doesn't open when I double-click the icon. I already tried uninstalling it and reinstalling it.

Initially, both internet explorer and Mozilla Firefox wouldn't open. After 3 months of not using my laptop, I decided to try to troubleshoot the problem. Miraculously, I could open IE today without having to do anything. But I was still having trouble with firefox. So I killed it in the task manager, and then I uninstalled it and reinstalled it. The loading icon would appear, but the window wouldn't open. So I tried opening it in safe mode. It worked, but like for 2 seconds. After 2 seconds of having it in safe mode, the window would freeze, I wouldn't be able to click anything in the window, and the top of the bar said "not responding". I'm not sure what else to do. Any suggestions?

I'm also using Windows 7 on a Lenovo U310 laptop.

I recently had to uninstall itunes and reinstall it again. How do I get my previously purchased music back on my itunes?

I recently had to uninstall itunes and reinstall it again. How do I get my previously purchased music back on my itunes?

Depending on what country that you are in you might be able to re-download past music purchases via the Purchased link under Quick Links on the right-hand side of the iTunes store home page - re-downloading : http://support.apple.com/kb/HT2519
But if you only re-installed iTunes and you didn't remove the actual music from your computer, then it should still be on there, and you should be able to add it back into iTunes via File > Add Folder To Library - by default your iTunes content should have been stored under :
Windows 7 and Vista : \users\username\My Music\iTunes.
Windows XP : \user\Documents and Settings\username\My Documents\My Music\iTunes.
