Itunes says 'this computer is not authorized to install apps on iPhone'... HELP

I can download apps on the iTunes store on my computer but after syncing it says 'Apps cannot be synced to iPhone as this computer is not authorized to install apps on the phone'... What do I do?

I don't know why you would be getting this error. I'd try to restore the iPhone and see if that helps.

How many computers are you trying to connect your iPhone to?

Open iTunes, in the upper left edge click on "Store", "Authorize Computer"

Just follow the prompts, you are authorized 5 computers per account and sometimes when you update software on iPhone or Computer it does something to your account. Just do the above and you should be good to go.

Note that it may be necessary for you to first deauthorize, then re-authorize your computer. That's what I had to do recently, when iTunes suddenly wouldn't sync 100 of my songs and all of my apps to the phone, with that same error. That fix worked for me.

another solution?

Hey guys, I'm having this same problem. I tried de-auth and re-auth my computer and still no luck. I also restored my phone to no luck.

Anyone else find a solution?

I had the same problem and none of the solutions I googled worked. I solved it for me by copying the apps with the finder (you can find them in <user name>/music/itunes/mobile applications) to another mac. If you open it there, iTunes will put them into the correct folder and you can sync your apps again. So I guess the problem lies with iTunes (8.1.1) on my laptop. Now I'll have to figure out how to reinstall iTunes on my laptop ...

Hope it works for you.

EDIT: After uninstalling iTunes following this guide, http://support.apple.com/kb/HT1224, everything synced again.

This Works

select song or app. that's not authorized, itunes will ask for your password, enter password, click ok, and ok again. Done.

Tried it all!

Although i have most of my apps and most of my videos on my computer a random few will not sync onto my iphone as "they are not authorized" I have tried deauthorizing and reauthorizing my account and still nothing. I deauthorized my account on another computer to make sure i hadnt used up my 5 computers and still nothing. I have tried doing the apps one by one and all at a time and yet nothing. Even if i remove an app from my iphone and then put it back on it is fine, it is just the select 10 or 12 apps on my computer that for some reason will not sync. **** This problem has occured since i got a new computer the apps the will not sync did used to be on my iphone! Can anyone help?

Post Possible answer for Jackattack4mac

I had the same problem when I switched from my laptop to a macbook. What I figured out was that I had purchased applications under two different email addresses. You can click on one of the applications that is not syncing and go to "File" then "Get Info" to find out what email address you used to purchase those applications. Hopefully this helps.

Sometimes a reboot of either the computer or the iPhone or both fixes this, if you’ve authorized already.

Subtle email differences are the key

I was baffled by this as well. I had two apps that wouldn't transfer; I tried reauthorising, deauthorising and authorising again and it still wouldn't work. I knew about the Apple ID thing but I was thinking "I have the one ID! It must be something else!" Until I checked the 'Store' tab in iPhone Settings...

Now, I thought I had the one Apple ID ending in '@mac.com'. However, when I checked my iPhone, it told me that my Apple ID ended in '@me.com'. Subtle, but enough to cause a lot of headaches. Authorising iTunes for the '@me.com' Apple ID sorted it. Hope this helps!

solution...

Clearly apps purchased within two different accounts will not update on the iphone, I had the same trouble. double click on the app icon in the app section on iTunes and authorize using the previous apple ID you purchase the items with. it will then upload all the apps back on the phone.
