Hello everyone,
When you open ZON Utility but it pops out a system error with wpcap.dll file not found problem as below image,

You may need to follow these steps to resolve the issue:
1. Download Npcap and Install it.
While installing Npcap, you need to confirm if "Install Npcap in WinPcap API-compatible Mode" is selected.

2. Install Npcap via Third-party tools. We use Wireshark as an example here.
While installing Wireshark, it will ask you if you need to install Npcap or not. Please select it to install.

After a few seconds, this window will be popped out. Notice that "Install Npcap in WinPcap API-compatible Mode" is not selected by default. Please check it and click install.

The issue should be solved if you enable WinPcap API-compatible Mode.
Feel free to let us know if you have any concern.
Hope it helps,
Adam
