Commandline for Winja.exe

I have tried to automate the sending of a file from within DOPUS to Virustotal with Winja without success via the command line.

C:\Program Files\Winja\Winja.exe {file}

What might I be doing wrong ?

A simple thing to try is to put quotes around the path, since it has spaces in it:

"C:\Program Files\Winja\Winja.exe" {file}
