Note 1: On Mac, after downloading, put CellProfiler in your Applications folder and ctrl-click (or right-click) and choose Open. Otherwise, you will receive a warning: “CellProfiler can’t be opened because it is from an unidentified developer”.
Note 2: Ignore the warning “Error loading pipeline file” - just click OK.
Note: On Windows, after downloading and launching CellProfiler, if you get the “Windows protected your PC” message, click “More info” to allow you to hit “Run anyway” to install.
