I am installing anti virus through LAN network, I've already seen the specified folder but when I click the setup.exe the message will appear "Windows cannot access the specified path or file, You may not have the permissions to access the item" I 'll try to ping the server and it ping, I'll try also disabled the firewall, and check the network sharing and security but does'nt work the message will appear again. I've already try to the other client and it was successfully installed. One client computer only can't access the server.

Hi, Where is the setup.exe saved? Please download it to the local hard drive and try again? If the issue persists, to avoid conflict with any application running background, I suggest install the antivirus in Safe Mode with Networking to check the result. Please refer to Start your computer in Safe Mode.
