Hi stephen,
How was dar file created? Is it created in another WFA setup and you are trying to import it to a new machine? If yes, could you share with me, I would like test it on my setup.
Did you try searching the command? sometime our eyes can't catch it . (Designer->Commands->(Keep mouse on Name column just beside icon ^). You will see another icon ' v ' appearing. Click on that and search for your command.
Regarding installation of 'pirate pack for vmware'. What is Pirate pack of vmware? How are you trying to use it in WFA?
Thanks
