Thumbnails for SU files do not Display in Windows 10


When I do a File Open in SU2018 there a no thumbnails displayed for each file, just the red SU icon.
Likewise, Windows File Explorer, thumnails are not display, just the ref SU icon.

How can the thumbnails be displayed?


When installing SketchUp, a .skp thumbnailer is registered in Windows Explorer.

A possibility is that the .skp thumbnailer is not properly registered or the reference to it is broken. Have you already tried a repair installation of SketchUp? (rerun SketchUp installer, it fixes SketchUp program files and registry entries but keeps user data unchanged).


Danke Sehr Aerilus. Once I did the Repair for SU2018, then the Thumbnail of each .skp file displayed.
