Properties+ context menu is missing in the Windows File Explorer

Symptoms

When SOLIDWORKS files are selected in the Windows File Explorer Properties+ command is not shown for the SOLIDWORKS files.

Reason

There may be multiple reasons why the command is not available

Properties+ is supported for SOLIDWORKS assemblies, drawings and part files (.sldasm and .sldprt). Menu command will not be shown for any other file type
In Windows 11 context menu can be set to Compact which does not display all commands
SOLIDWORKS assemblies and part files are not associated with SOLIDWORKS application (e.g. files can be associated with eDrawings application)

Solution

Select .sldasm, .slddrw and .sldprt files
In Windows 11 hold Shift button when accessing context menu to see the advanced commands
Register context menu command association by running the following regedit file

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\SystemFileAssociations\.sldasm\shell\Properties+\command]
@="\"C:\\Program Files\\Xarial\\CAD+ Toolset\\propsplus.exe\" --file \"%1\""

[HKEY_CLASSES_ROOT\SystemFileAssociations\.slddrw\shell\Properties+\command]
@="\"C:\\Program Files\\Xarial\\CAD+ Toolset\\propsplus.exe\" --file \"%1\""

[HKEY_CLASSES_ROOT\SystemFileAssociations\.sldprt\shell\Properties+\command]
@="\"C:\\Program Files\\Xarial\\CAD+ Toolset\\propsplus.exe\" --file \"%1\""

Run Properties+ from the command line

"C:\Program Files\Xarial\CAD+ Toolset\propsplus.exe" --file "PATH TO FILE"
