How to late bind Acrobat object in VBA?

The following code works perfectly in Microsoft excel VBA (Visual Basic For Applications).

Though this Early Binding version works , But if I use it in a workbook, I can not open the excel file on a machine that  Acrobat Pro is not installed.  Excel doesn't find the reference to Acrobat Pro, and all the functions stop working. I need to Late Bind the reference.

How can I change it to late binding?

Dim AcroPDDocNew    As New Acrobat.AcroPDDoc
Dim AcroPDDocAdd    As New Acrobat.AcroPDDoc
Dim lRet            As Long
    
lPages=0
lRet = AcroPDDocNew.Create()
lRet = AcroPDDocAdd.Open("E:\Test1.pdf")
lRet = AcroPDDocNew.InsertPages(lPages - 1, AcroPDDocAdd, 0, 1, True)

Thank you.
