Kaspersky fails to install the program due to network connection

Hello there,
I have this error caused by Kaspersky and it appeared when I tried to open the program after all my application started when my PC was turned ON. I can’t get rid of it and can anyone help me please to fix this ? Why I have this error and what is causing it ?
Thank you !

To continue installation you must close all application that can block access to local area connection settingS. If you are not sure which applications must be closed, reboot the computer.
