# Error pcap_dump_fopen could not be located in the dynamic link library

Hi,
When I’m starting the Suricata GUI on windows I’m getting the below error:
“The procedure entry point pcap_dump_fopen could not be located in the dynamic link library C:\Program Files\Suricata\suricata.exe”

How to fix this error ?

Version: Suricata 5.0.2-64bit IDS-IPS
I have installed npcap 7.80.

Hi,

Can you try installing https://nmap.org/npcap/dist/npcap-0.992.exe and reboot? (remove any previous installations too).
I think you are hitting - https://redmine.openinfosecfoundation.org/issues/2968
The installer should have poped instructions at the end of how to fix this (as I shared above)
Thank you
