この3つで使われているapigid32.dllってのを、標準のwin32APIに置き換えることはできますでしょうか？
copymovememoryとか、該当しそうなAPIがあるので・・・

Public Declare Sub agCopyData Lib "apigid32.dll" (Source As Any, Dest As Any, ByVal nCount As Long)
Public Declare Function agGetAddressForObject Lib "apigid32.dll" (Object As Any) As Long
Public Declare Function agGetStringFromLPSTR Lib "apigid32.dll" (ByVal src As String) As Long
