Preview Thumbnail Not Showing

[Kdmoo]

Ever since the first update to AutoCAD 2023, my thumbnail previews have gone missing.  I'm now in version 2024 and it's the same issue.  If I open and resave a file, the thumbnail will appear, otherwise nothing will show up.

When I browse in AutoCAD 2019 and 2022, the thumbnails are all there. (Yes, I have a lot of versions installed at the moment).

I have tried a number of fixes with no luck so far.  Any suggestions would be appreciated.

Thanks,

Kevin

Thanks for the link.  I tried all of those previously except for reinstalling.  Something changed in the AutoCAD 2023 first service pack update going forward that removed the previews.

@Kdmoo ,

Take a look at the suggestions from this post:

• Thumbnail Preview not showing up in file open dialog box

Also:

• THUMBSAVE (System Variable)

They are pointing to the "PreviewVisible" variable in the registry that I have been unable to locate.  Checked all the folders but not seeing it.  Will keep looking.

Thanks.

Same exact issue for me as well.

Any Update on this? I too have the same issue with multiple team members

No update.  Have learned to live with it but it's super frustrating.
