Problems while installing BSR screen recorder

Hello!
I have just downloaded the setup of BSR screen recorder . When i try to install it , setup paused at 41% . I have tried many times to install it, each time the same event happen. I have re-downloaded the setup, but again problem is not solved . I am unable to understand the problem, whether it is with software or with windows file. The following are the specifications of my PC,
Pentium IV with 2.8G Hz, 512MB RAM
Windows XP Professional SP2
Direct X 9
Following screen appears,
BSR Screen Recorder – Install
Copying files into temporary folder and expanding into install directory…
Please help i need to install it as soon as possible.
