I have found portable ren!and portable paind.net, gmax and xxc mixer and renx.
(i just need to install westwood online stuff and play!)
But i cant launch renx because everything is portable and the file stucture is not the same with the installed one.

Is there an other way to launch renx?for example you launch gmax than you click somewere and it restarts as renx?

just download the renpublic tools and gmax from here and install them, it works fine for me:

Anyway i fixed it
