SketchUp 2021 Thumbnails Don't Display

Technical Problems SketchUp
18

OK, to summarize:

  • You had some leftovers of earlier SketchUp Pro versions, but removed manually
  • Only version installed now is Version 2021
  • any new created file with SketchUp 2021 does not get a thumbnail generated. Only the SketchUp log is shown
  • from existing files only some have today a thumbnail.

Question:
If you open such a file in SketchUp 2021 and save it again as the same file version, is then the thumbnail gone as well?

If so, then the thumbnail generation seems completely broken and there might be some leftovers in the registry.
I do not know, if the following procedure helps, but you can try:

  • deinstall SketchUp 2021

  • make sure there are no references in the Windows registry anymore.
    If you are not familiar with the regedit tool, then do install again those versions of SketchUp you had once installed:

    • install SketchUp version 2018 and during install do NOT select any file types to be associated. Check Thumbnail generation. Then deinstall SketchUp 2018.
    • install SketchUp version 2019 and during install do NOT select any file types to be associated. Check thumbnail generation. Then deinstall SketchUp 2019.
    • Install SketchUp Version 2020.Check thumbnail generation. Then deinstall SketchUp 2020.
  • Install again 2021.
  • Hope it works :slight_smile:
