Why does flash player 13 installation fail at 50% installation on OS X 10.9.2?

When I install the latest flash player 13, the installation halts at 50%. My OS X 10.9.2 is up to date. I have run the uninstaller and have deleted any flash player files in my library application support file and preferences file. I have tried installing older, archived versions and similarly, the installation process halts in the process. I would appreciate any other thoughts!
