Hi again.

I hope this thread is not off topic. If so, where is the correct place 
to talk about luacom?

I can...

In fact, I tried a little bit further, and renaming dlls of luacheia 
allows me to successfull execute require("luacom"). Houra. And even 
better, in the directory luacom/demo/server if I type

   lua5 inproc.lua /Register

at the winxp command prompt, it leads to absolutely no warning nor error 
messages. But unfortunatelly the next step fails...

   lua5 inproc_use.lua

raises an error. In fact, calling

   local obj = luacom.CreateObject("testlua.Teste")

returns nil as it shouldn't.

Any suggestions?
