Windows 11 security features, or security information attached to a downloaded file, can sometimes prevent Clibor from launching automatically at Windows startup, even though it's set to start with Windows.
Try the steps below:
① Right-click Clibor.exe and open Properties
② On the General tab, under Security, check Unblock
③ Click OK to close the dialog
After this, restart Windows and check whether Clibor launches automatically from startup.
