I am using live Knoppix 3.7 with fromhd, PH on harddrive and config on USB stick.
As I reorganise my PH and configs regularly, I have downloaded Realplayer10 many times from klik with no problems.

I have tried to download and install it over the last couple of days. The download goes OK but it does not install. I have had no problem with Kaffeine, kplayer, Guarddog, Firefox, Flash and gdeskcal.
