EN: Restore SOLIDWORKS Thumbnails in Windows

If you have experienced the SOLIDWORKS Open dialog or Windows Explorer dialog not displaying the thumbnail preview picture, there are a few reasons that can cause their loss. In this article, we SOLIDWORKS thumbnail previews and share some solutions to remedy the issue.Ā 

1. SOLIDWORKS System options

Check the SOLIDWORKS System options- Tools > Options > System Options tab > general > Show thumbnail graphics in Windows Explorer.

2. Check the Windows Folder Options

Check the Windows Folder Options. Two options are needed, one selected and one de-selected.

First, open the Windows Control Panel > File Explorer Options.

The Apply button in the bottom right corner will no longer be greyed out. Select Apply.

3. Windows Performance Options

Note: SOLIDWORKS Thumbnails may be disabled if you have customized performance levels set in Windows. Also, if the top radio buttons are set to ā€œAdjust for best performanceā€, your previews and thumbnails will be disabled.

Start by going to Windows Control Panel > search "Performance" > select "Adjust the appearance and performance of Windows".

Select "Show thumbnails instead of icons" and apply as before.Ā 

4. DLL Registration

SOLIDWORKS installs many .dll files that are required for the program to run properly, interface with the prerequisites and work in the Windows O/S environment. If you install withoutĀ  full LOCAL Windows Admin permissions Ā it can prevent the needed registration of the .dll files. With the proper permissions, you can manually register the following .dll files to correct the issue.Ā 

  • Swdocumentmgr.dll (by default location - C:\Program Files\Common Files\SOLIDWORKS Shared)

  • Sldthumbnailprovider.dll (by default location - C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS)

To manually register these files, follow the steps below. If you have any questions, please contact your CAD Admin and/or IT team before starting.Ā 

  1. Log into Windows with full Local Administrator permissions

  2. Using Windows Explorer, browse to find the .dll files from the previous page (some paths may vary based on O/S).

  3. Open a Command Prompt (CMD) as Administrator.

  4. Enter the following text and enter after each

    1. Regsvr32 ā€œC:\Program Files\Common Files\SOLIDWORKS Shared\swdocumentmgr.dllā€
