Did we get a resolution to this? P3D is a 64 bit program whereas LuaCOM is 32 bit. The two are incompatible. That said, a registered version of WideFS7 with FSUIPC can connect to P3D and WideFS is and Pete Dowson said always would be a 32 bit program. Having the LuaCOM file in the same folder as the WideClient app with the Lua package.path and package.cpath set to the WideClient folder too allows WideFS to find the LuaCOM.dll file... I've done this today. However after finding the DLL file there is now a new error I'm trying to resolve, any help appreciated:
9140 *** LUA Error: error loading module 'luacom' from file 'D:/WideClient/luacom.dll':
D:/WideClient/luacom.dll:1: '=' expected near ''
