Nothing in tool menu after installation of plugins

I have 3 examples of plugins (Convert HTML Tags.bundle, RegEx.bundle, and EndNoteRenamer2.dll) found in this forum. When I put the plugins in the Plugins folder in my personal Endnote folder or in the folder of the application, nothing appears in Tools menu when I run Endnote…

/Applications/EndNote\ 20/Plugins



I use Endnote 20.1

Any thoughts ?
