Error message on opening layout on a MAC

Im new to Sketch-up. I downloaded the program , dragged it into my applications folder and when I open it I get an error message it isn’t recognized. Any ideas greatly appreciated

Are the icons of SketchUp OK, or do they have a slash through them? Where’d you download it from? If it wasn’t from Download All | SketchUp redo the download.

Your description omits some steps so I’m not sure whether or not you did them. The full process is:

  • download the installer .dmg
  • double-click the .dmg to mount it. An icon should appear on your desktop
  • double-click the icon to open the installer package. This should open a window on the desktop with a sketchup Icon and an applications folder icon.
  • in that window drag the sketchup icon onto the applications folder icon. After a moment you should see a progress bar telling you filed are being installed.
  • when the install complete, close the installer window and the eject the .dmg
