Just a few updates for users now that Knoppix 7.4 is still out. Under Knoppix 7.4 using Adobe Flash still requires running an install script (the install scripts now offer several additional pieces of software that they did not offer in 7.0). This was painfully slow, on my system it took about 45 minutes before I was told that Flash was installed successfully. However, it was not. Like 7.0 (which worked correctly previously but stopped working some time in July of this year), sites like Hulu tell me that I need to install Flash to view their content. As I used Knoppix mainly for web browsing, this will be a deal breaker for me.

If you want to run Abobe Flash under Knoppix I suggest trying to follow rajibando's instructions above. Or if you find yourself Linux challenged like me, try a different Live disc. So far Linux Mint is still the best version that I have found that comes with Abobe Flash already installed. I have also found that PCLinuxOS includes a working copy of Adobe Flash. It isn't working right for my hardware, the screen is defaulting to 3x4 aspect ration at boot even though the laptop and the external monitor are both 16x9 format (this can be easily changed after boot) and the audio isn't working correctly (and resisting fixing) (both Knoppix and Linux Mint get both of these right). Results on different hardware may vary, so if Linux Mint isn't right for you then PCLinuxOS may be another option.
