NSClient++ Help (#1) - Insatall NSClient++ too slow (#809) - Message List

Hi, It take about 30 minutes when I install nsclient++ 0.39rc1 in a server. The server OS is windows 2003 SP1. Due to the server is a very important server I couldn't researt it and install sp2. I want to know why the installation is too slow. How can I debug or resolve it?
