Installationsfehler bei der neuesten Flash Player Version für Mac OS X Yosemite

Hello

I've tried a lot now to install the the new version of the Flash Player but nothing helped.

However, neither the update, even an uninstall and then reinstall, or an installation in the Save worked mode (offline version).

My gatekeeper is configured correctly and I also deleted all Flash Player files from various folders on my computer.

What should I do now?

Thank you

Markus
