Dynare++: Caught Dynare 3xception:dynare3.cpp:65

I am trying to use Dynare++. I strictly followed the installation procedure of the Guide.
Maybe, I am still wrong. When I invoke the dynare++ directly from the Command Prompt as well as my .mod file,
I obtain the following message:

"caught dynare exception: dynare3.cpp:65: Could not open model file .mod

Where am I wrong???

Thanks,

M.

First: by your CMD goto the folder you put your mod file
sencend: Type command: dynare++ m.mod
if your file name is “m”
