MAC - Installation/Deployment PKG fails

Hi all,

I have a package created with CreativeCloudPackager. (containing CC2015 apps)
I've deployed the package several times on various macs and it always worked great.

But now it doesn't work anymore.

Deploying via ARD doesn't work.

Copying the PKG to the local machine and installing fails also.

some lines from the PDApp.log:

07/04/17 16:17:56:021 | [FATAL] |  | ASU | DeploymentManager | DeploymentManager |  |  | 5110 | The return code from the Adobe Installer Process is (7).Stopping the installation process.

07/04/17 16:17:56:021 | [ERROR] |  | ASU | DeploymentManager | DeploymentManager |  |  | 5110 | Media Failed (APRO15.0)

Apps install, but then disappear.

Thanks for any help.
