Re: Adding new paths for the access of embedded programs

["Luciano de Souza" <luchyanus@...>]

That's the problem. I have no error. There are two files: test.exe and 
test.lua. When I execute test.exe, I have no errors.
If it doesn't occur automatically, also I do know how to capture Lua's erros 
in a embedded program.
The fact is that I have no errors and path doesn't seem to be added. When I 
type at the Windows console 'c:>path", among the listed folders, there isn't 
the added one.
The worst thing is not have an error when in fact the error exists.
As I said, I have no erros, simple typing test.exe at the console the 
interface built with IUP doesn't open.
