Help with code downloading

my team has figured out how to make the code finally but we can’t get it to download onto the robot, we’ve tried installing and updating the firm ware multiple times but we just keep getting an error message

What software are you using to program it?

we have been using robotC

What does the error message say?

Also check the robot download target, and whether it is configured for USB or Comp Only. (These should both be along the top in menus)
