Each time I try to install the latest version of Adobe Flash Player on my MacBook Air (2 different laptops!) I can go through the routine well. I notice that after 57% installed it suddenly jumps to 100%, then I click the box 'Fertigstellen', and then I am back at the Adobe Installer Box, and I cannot find the Adobe Flash Player anywhere in my computer. I have gone through De-Installation of old version, and made a re-start. As this happens on both laptops with Mac OS X 10.8. I assum there is a fundmental flaw in the Installer.
