How to Add,Remove,Check references of different Office Application Dynamically?

Question

My Application is developed to scan Access DB forms to find out Activex Controls ( if present). Now my problem is:

When installing the application in a system having lower version of Office then it creates problem. Now I want to do this Dynamically i.e.

Need to Check, Add and Remove the Absent or Broken references of Office,Excel, Access or ADO etc..

Please let me know How to do this.

I got little success on tracing the Access Reference at Run time through Access object but not able to catch other references like Excel, Office etc...

Thank you!
