You need the MSVC 2005 redistributable kit. Remove the DLLs you added manually.
UPDATE:
if I build the dll through the windows IDE by setting a shared library project then I am able to link to such dll, even through the command line, that is:
ifort main.f90 try.lib
main.exe --> works
Now I need to understand which options are set through the IDE that are not with the command line,
needless to say that any help is much appreciated. Let me also say that I am a little bit disappointed with the time one has to spend to install and configure correctly the IVF.
Thank you
