I recommend you download and install the QUpdater plugin FIRST.

Download it and place it in your MUSHClient\worlds\plugins directory.

Open your global preferences (file->global preferences), click on Lua and remove the sandbox stuff in the dialog box. Make sure 'Allow DLLs to be loaded' is checked ON.

Open the plugins menu (control-shift-p) and click Add. Find the Qupdater plugin and add it.


Now you can 'qlist' to see a list of available plugins, and then 'qinstall <pluginname>'.

E.g.

'qinstall ats_navcomp'
