Custom Dissector Plugin not found after place it in Personal Plugins folder

I have compiled a dissector plugin following this guide. If I place the resulting '*.dll' in:

C:\Program Files\Wireshark\plugins\4.0\epan

My plugin is found and it works as expected. But, as it is a custom plugin, I have considered that it should be placed in Personal Plugins folder:


Doing so, it seems dissector is not found:

Error loading table 'User DLTs Table': user_dlts:2: dissector not found

Am I missing someting? Is there anything wrong on WireShark custom plugins awareness?

Many thanks!

Have you tried adding the epan level under plugins\4.0 and placing the plugin there?

B.4. Plugin folders

Wireshark looks for plugins in both a personal plugin folder and a global plugin folder. Lua plugins are stored in the plugin folders; compiled plugins are stored in subfolders of the plugin folders, with the subfolder name being the Wireshark minor version number (X.Y). There is another hierarchical level for each Wireshark plugin type (libwireshark, libwiretap and codecs). So for example the location for a libwireshark plugin (foo.dll on Windows) would be PLUGINDIR/X.Y/epan (libwireshark used to be called libepan; the other folder names are codecs and wiretap).

Thanks @Chuckc. Indeed, I was missing the "epan" folder inside Personal Plugins. Now it works, Many thanks
