cannot get sketchup plug in for autocad 2013 to load

[rjb.192694]

I recently installed AutoCAD 2013 on a new Windows 8 (64bit) PC. All good except after downloading Sketchup plugin, it will not load. I get message to say its installed but it does not appear in User/AppData/Roaming/Autodesk/ApplicationPlugins folder as it should. Anyone got any thoughts?

I sorted this myself in the end. I simply had to manually load it via APPLOAD. Still not sure why it didn't auto load. Oh well........!
