Add new citation styles to Microsoft Office installed on Ubuntu via Play on Linux

I wanted add some more citation style on MS office, installed on UBUNTU via Play on Linux. I followed the following steps

1. I downloaded the more citation sources  from http://bibword.codeplex.com/
2. I searched for PlayOnLinux's virtual drives on my Ubuntu system
3. Then I copied the unzipped style to PlayOnLinux's virtual drives/Office2007/drive_c/Program Files/Microsoft Office/Office12/Bibliography/Style

Now I can see many more citations.
