How I did it so change accordingly
1. My Tomcat is situated in c:\server\tomcat directory
Download the pentaho-server-manual-ce file
2. Change server.xml (..\tomcat\conf) if needed
3. Unzip pentaho-data.zip and pentaho-solution.zip in c:\server
4. Place pentaho.war andpentaho-style.war in ..\tomcat\webapps directory
5. Place database driver files in ..\tomcat\lib directory
