I have 2 pc for my iOS devices and I turn on my Home Sharing to transfer music and apps from my 1st pc to the 2nd pc. The music transfer just fine, but about the apps some can transfer but some can't. The error said I can't transfer those apps because I didn't authorize on my pc but even though I did authorize both pc. So I went back and authorized to make sure that I did, both my pc said " Including this one, you have authorized 2 computers out of your available 5" that's really frustrated and anoying me. PLEASE if someone out there who knows how to solve this, reply this to me as soon as you possibly can. Thank you.
It sounds like you may have some applications purchased under another Apple ID. I would recommend finding the account name of the Apps that will not transfer and authorize the computer for that account. To find the account name, see the section labeled Authorize using the correct account name in the article below. Alternatively, you can either Right-Click and Get Info on the selected App for Windows or Control-Click and Get Info for Mac. The Apple ID that was used to purchase the App will be on the Summary tab.
Hope that helps.
