V5 PROS Error

Hi everyone,

I recently installed PROS, but when I try to download the program using the installed Atom Editor, I get the following message: “ERROR - pros.cli.upload:upload - could not open port ‘COM8’: PermissionError(13, ‘Access is denied.’, None, 5)” Does anyone have any insight onto what the problem is.

This is typically because you have another program (ROBOTC, Firmware Utilities, VCS, or RMS) that’s preventing PROS from accessing the communication port to the brain.

We’ve updated the error message and it’ll be in the next release to make it more clear.

Oh, so all I need to do is close VCS and it should work?

Yes.

All right thanks a ton.
