how do I authorize my computer to install apps?
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.
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 ...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?
