Thanks John for your reply. my main problem was the inability to get the plugin into s/u plugin extension window, (there was no install extension button.) I finally found a s/u 8 m2 update and now works fine. Jim

when attempting to open a .rb plugin the following error message appears (This does not appear to be a sketchup model). This holds true for any plugin file in the plugin folder. Sure would like to get this straightened out Jim
