When using SketchUp on Windows Vista or Windows 7, you double-click the "SketchUp" shortcut on the Desktop or from the "Windows" button, and SketchUp freezes or loads a blank window.
How to fix it:
To resolve this issue we recommend downloading the latest drivers for your video graphics card.
If you have a nVidia video graphics card, please make sure you follow their eight-step installation instructions.
If updating the video card driver doesn't resolve the issue, try launching SketchUp by double-clicking on a SKP file. If you haven't created a new SKP file yet, you can download one from the 3D Warehouse.
Please note that we suggest continually checking with your graphics card driver provider for new Vista-compatible drivers.
