Hello,
This problem seem caused by Windows antivirus, if redownload and reinstall WRobot in new folder don't works, disable "Windows defender" and reinstall WRobot in new folder
Hello. As written in the "Privacy Policy", only trial subscriptions can be refunded (at 2.99€) (one time by user, if you request refund before the end of the time).
Do you use Windows defender, if yes try to disable it and reinstall WRobot https://www.windowscentral.com/how-permanently-disable-windows-defender-windows-10#disable_windows_defender_settings
