Weidu for Mac Installation Clarification

Hi,

I've downloaded Weidu and want to install it. From what I've read, I need to copy "Weidu" App from the the Weidu-Mac folder. However inside the folder I have the following files:

bin Folder
amd64 Folder
mospack File
mosunpack File
tispack File
tisunpack File
weidu File
weinstall File

x86 Folder
mospack File
mosunpack File
tispack File
tisunpack File
weidu File
weinstall File

examples Folder
lib Folder

Firstly I'm guessing I need to copy "weidu" from the bin/x86 folder? Secondly, do I need the other files/folders, if so do I have to put them anywhere special?

Thanks a lot
All the Best
Dave
