App says "installing " but does not install, iOS 6

I get this same problem on my 3gs, ever since i got io6. I go to get the app, click install, type my apple id in. It says installing then it just stops and goes back to the install icon.

What is the fix????????

Try:

- Reset the iOS device. Nothing will be lost

Reset iOS device: Hold down the On/Off button and the Home button at the same time for at

least ten seconds, until the Apple logo appears

- deleting and reinstalling the app

- Download on your computer and sync

I tried the reset. It fixed photos not saving. But it didnt fix the app problem.

Ill try getting the app on my computer

Tried downloading the app on itunes, said downloading, go to my iphone, app is not on there, the app store says its downloaded. But its nowhere to be found.

Go to Settings>General>Storage and see if the app is listed. If it is then tap on it and select Delete.

Next would be to restore from backup

my 3gs does not have storage in setting>general....

i just want the facebook page manager and clash of clans,

it still updates all my current aps fine, just cant download anything new

Restore from backup

how, also will that wipe all photos?

The backup included all items in the Camera Roll album in the Photos app.
