I have a problem loading Vray, getting this message on startup all the time: "Error Loading File VRayForSketchUp.rb
127: The specified procedure could not be found.
C:/Program Files/Google SketchUp 6/Plugins/VRayForSketchUp.so"
If you’re using a later version of Windows than XP, try setting compatability mode of the installer to “Windows XP SP3” and be sure to right click and run with Administrator privelidges when you install.
You have remains of an old version.
Uninstall all entires of V-Ray from the control panel - then ensure the Plugins folder does not contain any VfSU files or folder. Then reinstall.
