I've tried to install in XP it also crushes. One thing I've noticed is that the installation have an option of installing the documentation of the plug-in, but even if I select this option I do not see any related documentation. Could it be the wrong plug-in? (I downloaded it from a link in http://www.graphisoft.com/products/archicad/solutions/sketchup.html, I'm sure it is for AC 10)
