This error message often shows when you just close the program, and immediately you re-launch another instance. That’s because the first instance you closed still exists in the background, which takes a little while to release itself. When you launch a new one, you get conflict. Therefore, please wait for a while (30 seconds will be enough) to run Capsa again after you close it. Or, you can kill the process, named Capsa, in the Task Manager if you need to launch Capsa immediately.
