Reader does not support OLE. If you are developing in Acrobat, check that you are creating objects properly.
Issue
I wasn't able to use the objects in the PDF.tlb file despite them being visible in VB. When the program is compiled the error "Can't create Object" is displayed.
Solution
Unfortunately, Acrobat Reader does not support OLE automation, as stated in the Interapplication Communication Overview located in the Acrobat SDK. Therefore, your options are to upgrade to full version of Acrobat, where OLE is supported.

If you are using Acrobat, the problem may relate to how the objects are created. Your code should be similar to:
Dim avdoc as Object, app as object, pddoc as Object
set app = CreateObject("AcroExch.App")
set avdoc = CreateObject("AcroExch.AVDoc")
avdoc.open "c:\test.pdf", "Temp Title"
if (avdoc.IsValid = True) Then
set pddoc = avdoc.GetPDDoc()
End If
