microsoft report viewer 2008 not detected

Hi all,
I just installed reportviewer.exe 2008 on my PC, then restarted it, then tried to locate it through visual c++ 2008 express edition right clicking on my tool box but it never appear... I did try 3 times but nothing happens... I looked for the report viewer folder but windows cannot find it... can someone help me with this unusual issue...??

Thanks

ps: I'm working with vista and framework 4.0
