The capture session could not be initiated on interface '\Device\NPF_Loopback' (Error opening adapter: Er is een niet-bestaand apparaat opgegeven. (433)).
after installing wireshark i cant seem to capture because the npcap driver isnt running.
i have tried to start it manually with: net start npcap but i get systemerror 2 the system cannot find the file specified
when i look in C:\Windows\System32\drivers the driver is there.
i've been unable to find a working fix for it so i hope anyone here could help me out.

It helps if you include the information from "Help->About Wireshark" or "wireshark -v".
The latest version of npcap is Npcap 0.9983 [2019-08-30].
You might uninstall then reinstall to make sure its a clean install.
Download here: https://nmap.org/npcap/
The npcap Diagnostic Report and install logs might have useful info.
https://nmap.org/npcap/guide/npcap-us...
The npcap installation also has a batch file that attempts to correct service registration and startup,
FixInstall.bat
that should be run from an elevated prompt, but before running that can you show the output of the npcap service status and configuration withsc queryex npcap
followed bysc qc npcap
Requested output:
I don't think this is contributing to your issues, but it seems that you've installed npcap in "Winpcap compatible" mode:
Unless you explicitly need that for another application that can only use WinPcap, Wireshark doesn't, you might want to reinstall npcap and uncheck that box on the installer.
i've tried that aswell but it doesn't make any difference, i keep getting the same error.
