Unfortunetelly no. Already try that, but the error persists

Did you add Design Days on the "Location" Tab (the first one, below where you add the Weather File) ?

@RicardoCordeiro could you please update your post to add screenshots of the Site tab (where you assign EPW and DDY files) and the Simulation Settings tab (where you turn on Zone Sizing, System Sizing, etc.). Including a screenshot of the error message would also help.

I just battled the same error, using a simple unitary system in each of seven air loops. Turns out I had 1) moved my weather file from where I thought it was and b) perhaps more importantly, forgotten to insert an air terminal (here: AirTerminal:SingleDuct:ConstantVolume:NoReheat) before each zone in the air loop. Was panicking there for a bit, but then remembered I had made that same omission a few times before.
