Can't say anything about the actual issue, but the dirs are correct, on 64bits syswow64 is for 32bit libs.
However, it is a bit strange that the disappearance of the wpcap.dll in the system32 directory would affect the operation of 64-bit programs.
It's confusing, but that's where 64-bit dlls are on 64-bit Windows.
Can you attach a WINEDEBUG=+wpcap log?
I have uploaded the compiled binary program to the attachment, and it can be directly run with Wine
64-bit works here. Whether this works may depend on your system too. Please attach a WINEDEBUG=+wpcap log from the 32-bit version for which you filed this bug.
