Macromedia Flash Player Install-no Admin. Previlege?

I am new to the Portable Firefox although I use firefox as my default browser on my own desktop.
I have installed PFF on a flash disk to be able to use it whever I go. However when I tried to use it on my office pc I am not ale to view sites which require/use mcromedia flash player. I do not have administrator previledge in order to install the flash plugin so as of now this "portable"webbrowser is really a crippled one for me.
My question now is that is there a way to install the plugin "manually" i.e. copy and paste? I know that in BartPE cd this is done.
