Can i run different versions of the same program on the same computer? Regarding itunes 10 and 12?

I have used itunes as my default audio player on windows 7 for a long time however i only enjoy itunes version 10.7 wich is the last version to have the album cover view that you can flick, and being a android user i don't need the latest versions of itunes 12 to sync with my phone, however my cousin who uses my computer has the iphone 4 and needs the latest version of itunes 12 to be able to sync is there any possibility to have both version of itunes on the same computer as for example in diferent windows users,
any way of doing so is greatly apreciated thank you in advance

No you can have that, even if you create separate account for your cousin, once you install the later version it will automatically upgrade the previous version

  • What is the difference between newer and older versions of the Mac computer? If I want to create an iPhone app which would be most useful. The newest Mac computer or the 2006-2007 MacBook on eBay for 400 dollars.
  • Two different computers, two different iTunes.can I use the same Apple ID? I have iTunes on my computer that I use for my iPhone, and my mon just got an iPod Touch and wants me to fill it for her. I'm going to use her computer to do this, which currently does not have iTunes. Once I download iTunes, can I use my own Apple ID to download songs and apps onto her iPod? Is it possible to do that without disturbing what's on my phone, or do I have to make a whole new iTunes account for her?
  • Transfer iTunes library to a different account on the same computer? My mum hates that my siblings and I put all of our music in her iTunes library because we don't have a computer of our own. I just created a new account on her computer (MacBook Pro) for us, but I can't seem to transfer our songs to that account. Every time I try to transfer the songs from my iPhone (same songs as on my mum's iTunes), it says that they've been transferred but the library stays empty. Any suggestions?
