AcroRd32.exe opens when trying to merge multiple PDFs

Using Version 1.6.2:
In the Microsoft Office environment, using VBA, I am using the following code to merge multiple PDFs into one large PDF. The code works perfectly, but at the indicated line, adobe reader (“AcroRd32.exe”) opens up, and i have to manually close it. I’ve tried to use other VBA subroutines to close AcroRd32.exe, but the entire code get’s stuck on the indicated line UNTIL I close it manually. any help would be greatly appreciated. .
