How to add reference to scrun.dll to run a .rea Macro

I have a .rea macro that use a filesystem object and so we need to add the "Microsoft scripting runtime" dll reference in the vba project

To start the deski that uses this macro, we have a vbscript, this script should add the dll reference (scrrun.dll) in the registry on the computer.

The question is :

What are the modifications we have to do in the registry to add the reference to the "Microsoft scripting Runtime" in the registry ??
