Did you recently copy your code from one computer to another, or did you rename the project directory? Check the local destination directory. Make sure it points to a directory that actually exists.

In the project explorer window, right-click on FRC Robot Boot-up Deployment and choose Properties.
Click on the Information Category in the left-hand pane.
Verify the Local destination directory. If the user name and/or project directory is wrong, correct it.
