@Integralist, I faced same issue, just install graphviz to your system, depending on OS you have to add dot.exe directory to PATH variable. After reloading command terminals opened everything worked fine.

Awesome. Thanks @reflash

@reflash, So I clearly need some help with this. I am getting the same exception but I am not clear as to were to add the dot command or directory. Thank you.

@spatran137, Can you give some details? Not sure what problem you have. If you installed graphviz - then just find the directory path, where the dot.exe exists and add it to system PATH variable.

@reflash, So that was my issue I did not put the directory path in the system PATH variable. I was not thinking right I put it in the User variables. Once I put it in the system it worked. Thank you for your help.
