Chyrsalis 0.11.1 uninstall fails, thinks it's running

When I try to uninstall Chyrsalis 0.11.1 it tells me “Chrysalis is running. Ok to close it.” but Chrysalis is not running so it fails to stop it and does not uninstall. I have tried this immediately after rebooting the machine. Is there something i can do manually to clear it’s running instance detection?
