Need code to merge PDF files in a folder using adobe acrobat X

[ZVI]

I am using Excel professional (Office professional). I am using the free Adobe Reader edition. I am sorry but I do not have Acrobat X Pro.

Adobe Reader Version XI should work, hope that its reinstalling will help.
I'd also temporary check the code in the new created workbook without reference to Microsoft Access Object Library shown in your attachment of post #17
