" iTunes Sync - failed to install " - Push Notifications

Hi, i´m trying to install a adobe air 3.9 for ios as development aplication with Notifications.

I create a new APPID with "Push Notifications" and then created a certificate for this push notifications (1 for dev and 1 for prodution) .

I create then "Provisioning Profile" where i choose my APPID.

I converted the *.cer to *.p12 with openSSL....

I set everything in Flash, and i changed my XML to contain :

<iPhone> <InfoAdditions> … </InfoAdditions> <Entitlements> <![CDATA[ <key>aps-environment</key> <string>development</string> ]]> </Entitlements> </iPhone>

Following : http://www.adobe.com/devnet/air/articles/ios-push-notifications.html

When i trying to install the app via iTunes,

" iTunes Sync - failed to install ".

Can anyine help me ? Thanks in advance!
