OK. Finally I was able to install and use it in my system after installing VC++ 2005 Redistributable Package:

So if anyone is facing similar problem, then install the packages and then install yahoo! messenger 9.0 Beta.
And finally I'll hv to say. Kya copy-cat hain. Totally WLM ko copy kiya hai. Similar contact list, similar button in chat windows to collapse the friends and your avatar. Also the interface also matches WLM. Badhiya hai.
