I am a new user to rational robot.
I am getting "Unable to create Test Datastore" error, when I am configuring a new project using rational administrator. Here I am using Microsoft Access as testdatabase.
First check if Microsoft Access is installed in your system properly. If you have SQL server. You try to choose that option and see. And more over you choose the path correctly.Crete a new path.
I hope u must be able to do it.
