I need to download and install itunes for my iphone?

Everytime I download and install one it says that it did not install correctly. From which site do I need to download it from and what version? My pc is system type x64-basedpc windows\system32 version 6.1.7601 service pac 1 Build 7601 dell inspiron one 2205.

Make sure you have enough memory to install itunes onto your computer, go to start, then computer and Local disk (C) should have at least 512MB free. Another thing is to check your internet connection is good, move close to your router or go wired and it should download better, as sometimes if your connection is slow it will miss a file to download.

Itunes link: http://www.apple.com/.../download/

Requirements for itunes:
PC with a 1GHz Intel or AMD processor and 512MB of RAM
Windows XP Service Pack 2 or later; 32-bit editions of Windows Vista, Windows 7 or Windows 8
64-bit editions of Windows Vista, Windows 7 or Windows 8 require the iTunes 64-bit installer
400MB of available disk space
Broadband Internet connection to use the iTunes Store

  • Why won't Cydia download/install anything on my iPhone? I just jailbroke my iPhone 4 w/iOS 6.1 today. But when I went to install the winterboard or any other program it won't work. Messages like "Internal Server Error", or "Timed Out" or "Source Error" comes up in red letters. I've tried on 3G and my Wi-Fi connection and it still won't install anything. Any thoughts people? Are the boys at Cydia or the other sources still working on iOS 6.1 stuff?
  • Why can't iTunes download and install iOS 7? I can't update to iOS 7 with just my iPhone. I need Wi-Fi. So I've tired downloading and installing 5 times already in iTunes. Each time it tells me it's gonna take 25-26 hours. But when it gets to 21 hours left, a small page would appear saying "An unknown error has occurred (9006)." It's getting me frustrated. Is there something I'm doing wrong while updating to iOS 7?
  • Why can't I download and install iPhone update? I have an iphone 4s, currently version 5.1.1 (never bothered to update), and I want to update it to ios 6.1.1 (I have a notification on my iPhone settings). It says that I must have at least 2.8GB of data available, I've checked and I have this exact amount of data free… However, the button on the software update page saying 'download and install' is greyed out and I can't click on it. Can someone help, please?
  • Where to download IPAs and how to install them? So, as you may know installous no longer works, and I found the appcake+ to be a good alternative, the only problem with it is that it can't download IPAs, it can only use the IPAs from the downloads I made with installous. By that I understood that somewhere in my iPhone there's a folder with all the cracked IPAs I downloaded. My question is, where can I find sites that allow me to download games' IPAs and what folder should I look for in my "iPhone folders" program.
