Hi Steve, > ZBS=C:\Program Files (x86)\ZeroBrane > LUA_CPATH=C:\Program Files (x86)\ZeroBrane/bin/?.dll;C:\Program Files > (x86)\ZeroBrane/bin/clibs/?.dll > I get: > Failed to load file : error loading module ‘socket.core’ from file > “C:\Program Files (x86)\ZeroBrane/bin/clibs/socket\core.dll”:The specified > module could not be found. I think you are loading Lua 5.1 modules to use with Lua 5.2 and this is causing the error you see. Try changing LUA_CPATH to C:\Program Files (x86)\ZeroBrane/bin/?.dll;C:\Program Files (x86)\ZeroBrane/bin/clibs52/?.dll (note using clibs52 instead of clibs). If that fixes the issue for you, I'll update the documentation... Paul.
