I just download wire shark 64bit version and isn't activiting to capture traffic? Can any one give some feed back? thanks good day
I don't have administrative rights on my Win7 Pro (64 Bit) system. Capture works without a problem.
That's probably because the NPF service is installed and running, allowing non administrative users to capture on the system.
