Error: Could not find Graphviz in PATH.

[bennycode]

Hello, today I installed Graphviz v2.38 (using graphviz-2.38.msi) on Windows 10. Afterwards I tried to run tsviz src/ diagram.png but I only receive this error message:

Could not find Graphviz in PATH.
events.js:160
throw er; // Unhandled 'error' event

So it looks like your tool cannot find Graphviz. Do I need to add a specific .exe to my system variables?

Just had this issue on Windows and resolved it by adding C:\Program Files (x86)\Graphviz2.38\bin to my PATH environment variable. Worked fine after that.

After inserting to PATH don't forget to Sign out and in for windows to reload the environment variables, it will save you a lot of rage and time. Just saying... no real experience... (17 minutes...)
