I need to remove ActMon from my PC but deleted the uninstaller already.
Reinstall ActMon. Then uninstall with the standard uninstall function: To uninstall open ActMon Commander, click on the SETTINGS tab strip, click Uninstall (Home Edition) or click the "Advanced Installation" button and then the "Uninstall" button (PRO Edition)
