Qucs-s error with simulation: “ERROR: Cannot start qucsator.exe (Process failed to start: etc...)

I just downloaded Qucs-s to look at some files with components from NG-spice but when I simulate it I get an error "ERROR: Cannot start qucsator.exe (Process failed to start: No such file or directory)". I have installed regular qucs, NG-spice and I can see that I have qucsator.exe in my computer from when I installed qucs. Has anyone else dealt with this issue before, if so how did you fix it?
