You should install OD first, then the database, then TeamSite. That way, TeamSite installation can pick up all the necessary files so you don't have to do the post installation steps.
The 6.7.2 Teamsite Installation Guide for Windows has the OD install as a prerequisite to the Teamsite installation. Vinay should follow the guide.
Ooooh, smackdown of Bo. CC, you need to gloat more when you catch Bo like that. Now this is a significant departure from the norm, because (as Bo noted) before 6.7.2, you installed TS first. Now it does mention to install OD first.
I hope Boris does not gloat when he catches my mistakes......
