Description

Hi,
i tested my sw based on Npcap and SharpPcap (C#) on some systems.
Windows 10, Windows 8.1, all is OK.
On Windows 7 32bit and Windows 7 64bit, I receive error Can't compile filter (https://snipboard.io/GjAdCh.jpg).
When I unsintall npcap and install Winpcap instead, my program is working without errors.

Research direction

Start by reproducing the filter-compilation error in the reported C# application with Npcap on Windows 7 in both 32-bit and 64-bit environments, then compare the same setup with WinPcap. The issue is resolved when the filter compiles and the application works on both Windows 7 variants; the specific filter expression and reproduction details are still missing.
