I recently tried to update my iPod Touch 4G to iOS 6. I originally tried it on a newer computer, not the original computer I had synced the iPod to. I saw that it would delete the apps and music because this was not the original computer, so I backed up my iPod and transferred the purchases. However, whenever I click on an app in iTunes, I get the message "The app --- can't be used because the original file could not be found. Would you like to locate it?" When I try to locate the app, there are only a few apps that are actually in the folder.


Then, I went back to the original computer. When I tried to update the iPod, it started to back up very slowly. When I came back a little later, nothing was happening, and the backup icon had disappeared. When I clicked the update button again, it started the same process. When I Googled that, it told me to restore my iPod. I would do that, except it had stopped syncing to the original computer, and because I'm not sure if the apps are on the new computer, I don't want to take the chance of losing my apps.


It appears that I am stuck in sort of a paradox. Help!

iPod touch, iOS 4.3.2

App data is included in the backup that iTunes makes. The data is not included with the app in your iTunes library.

The error you got when updating on the other computer means that for some reason iTunes forgot where it transferred the app to.

Is there an iPod backup shown in iTunes>Preferences>Devices? Is so try restoring from backup but first make sure that all the apps are in the iTunes library. If necessary redownload by:

Downloading past purchases from the App Store, iBookstore, and iTunes Store
