Dear friends,

I have downloaded and installed cygwin 1.7 on my windows 7 PC for installing ns2.
But whenever I run the command ./install
The error that comes is attached.
I am totally novice to this environment. Please help with this.
I visited Scriptics.com as suggested in the error msg, but the sit is not proper.
Please help.
