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:

Tgi3D_SU_Amorph_Training_Edition-1.27-Setup.exe
LibFredo6 4.6c - 11 Jul 12.zip
lss_toolbar_2_0_beta - resources.zip
TT_Lib2 - 2.6.0.zip

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