Packaging Problem for Android using UE 4.16

Hello,

I’m new to UE so there is maybe an easy way to solve my problem.
I want to package a project for a mobile phone. But there always appears an Error:

UATHelper: Packaging (Android (ETC2)): Das System kann den angegebenen Pfad nicht finden.
UATHelper: Packaging (Android (ETC2)): UEDeployAndroid.RunCommandLineProgramWithExeption: Updating project.properties, and build.xml for play-services-ads-9.2.0…

Further it worked with UE 4.15.2. But I installed the preview version 4.16… Since this time it doesn’t work.
I uninstalled all versions and installed them again. But it doesn´t work.

Maybe you can help me to fix the problem. Would be great. Thanks a lot.

It works now. I don’t know why, the error is already shown, but the result is what I want.
