Accessing dot net exe from navision automation

Hi All, I have a dot net exe file which i want to access from navision, I created a dot net type of variable but in sub type list i am not able to find the appropriate type to pick.

Note the exe i am trying to install opens a command prompt with blinking cursor, think it doesn't get installed also.

Checked with client he said no need to install exe.

If any one has worked on accessing dot net ex
e from navision, please help.

Many thanks in advance
