Raw sockets limitations in Vista and Win7
Due to current limitations in the raw sockets implementations for Windows Vista and Windows 7 we suggest running RawCap on Windows XP. The main problem with raw socket sniffing in Vista and Win7 is that you might not receive either incoming packets (Win7) or outgoing packets (Vista).
