Trajectory setup- output

[saeas4]

Hi there,

I am having trouble running my trajectory that I have setup in the "setup run".
Once I put in all the information, I press save and the program closes as it should.
But then when I go to trajectory- run model, the simulation log comes up with this message: "Model started... couldn't execute "C:\Program": no such file or directory"

How do I fix this?
I think the issue is due to where I'm saving it in the output file. I tried saving it on my C drive and then on the desktop. But neither worked. Where should I be saving it/ what should I be putting in the output (/path/file) ?

Thank you in advanced!

Cheers,
Steph

You should work on directories that do not have spaces in their names.
For instance, install hysplit in C:/hysplit4/
