[ns] want ns2.1b7 run in windows 98

[zhangkehuan@163.net]

i will use ns under windows98 to do some demostration of network protocol. i have download "ns.exe" at ns main page,but its version is 2.1b5,whitch is relatively older version. so i met many problems, that will error under windows with ns2.1b5,but will pass and get correct result under linux with ns2.1b7 .since i use only ns ,so i won't to compile a ns by myself. can anybody , who works under windows and with ns version 2.1b7 , send me a copy of ns.exe(2.1b7)?
thanks in advance .
yours zhangkehuan.
