I have a Macbook Air and Flashplayer just freezes when i try to install it.
Download the FULL Installer: Flash Player 188.8.131.52 (Mac OS X)
Save the file, quit your browser and mount the DMG.
DO NOT RUN the installer.
Right click (Ctrl+Click) and choose "Show Package Contents"
Then in Contents/Resources, double click the Adobe Flash Player.pkg
and run the COCOA installer
