Comments
The filename shown in the error message is included in the 'Select files' panel. The file is from the 'Build directory' that you specified on the Build | Run panel.

Remove the file as it's currently specified from the 'Select files' panel. You can make a copy of the file in another directory and select that copy in the 'Select files' panel.
