Right click on xampp-portcheck.exe (in the xampp installation folder if you have got that far) and select to run as an administrator - but may not tell you what you want to know in Vista or you can use netstat or tcpview - your Windows Help could be useful to learn how to use the last 2 or try:

netstat -anop TCPCheck the PID number with the Task Manager>Processes tab.
