Firing a macro at open and close of a drawing, on some machines I get an Error code 429. I have a reference to the Microsoft ActiveX 2.7 object library, and the msado15.dll is present on all machines. Trying to setup a begin_close event. On some machines, I recieve the error "Could not create the ActiveX object(or something to that effect), while others work fine. The code reads as follows: Public WithEvents ACADApp As AcadApplication Sub Example_AcadApplication_Events() Set ACADApp = GetObject(, "AutoCAD.Application") End Sub Any ideas on why it doesn't work on all machines? Running Acad 2K4, WinXP. TIA
