Error while adding Object to Object repository at run time

[dubeyvin]

Can we also Rename Object's Logical name at the Runtime?
I tried with the following code :

Code:

Set mR = CreateOBject("Mercury.ObjectRepositoryUtil")
    mR.Load "C:\Users\Documents\ObjectRepository.bdb"
    mR.RenameObject Browser("TEstFolder").Page("abc"),"def"

I have tried to save it in the VBS file and then attached to the Test
But I am getting Error as : Object Can not be Renamed

I have also attached the Screenshot of the error
