Sketchup for Windows XP free and plugins


What version of Sketchup free do I need to download and where? I tried Sketchup Make 2015 to install and it says it needs W7. I have Win XP.

My last Sketchup version was 8 so it is quite years ago I was working with Sketchup. So I want to ask which of these plugins should I install or update:

LibFredo6 4.6c - 11 Jul
lss_toolbar_2_0_beta -
TT_Lib2 -

Is it possibible to install these plugins into the new Sketchup?
