More for my future reference but if trying to set up the flash player debug version on chrome then you have to know a couple of things. Firstly chrome uses its own integrated flash player which attempts to keep up to date with the latest version. Secondly if this is switched off then it will look on the system for a flash player to use.
So.. you need to disable the chrome application flash player and then grab and install a version of the flash debug player you need from the adobe site. Once done you can check the version in use by going here.

Proper instructions are on the adobe site on this page:
