It is essentially to follow exactly as I wrote, nothing more nothing less.
- Close your SketchUp, then reopen SketchUp.
- Select the menu with mouse: Windows>>3D Warehouse
- hold the โ Winkey and hit the โright arrow key several times, until the 3D Warehouse windows appears.
The most important is to do not click with your mouse or do not hit other keys as written after selecting the 3D Warehouse menu.
