Hello everyone,

I have a problem when I run rendering,with any render node and any rendering.

Houdini consoloe say “CreateProcess failed for ”mantra“

And the error on mantra node say ”Unable to execute program “mantra”

Is it a problem of driver or firewall? I don't kwow…

I show you screen for more details.

If anyone had an answer to this problem it would be great,


Thanks,



Bastien HAMIDI.
