The question is not stupid as you may think
On my win7 64 bits machine I don't have an entry for vba for autocad map 2011 but in the application if I press alt+F11 the vba windows appears
the name of that process that is launched is called x64VBAServer18
So As I know autocad doesn't suport VBA so from where I disable VBA?
in my mechanical 2011, VBA was installed seperatly and so i see a entry 'AutoCAD 2011 VBA Enabler'.
Maybe VBA is included in MAP2011?
Try to download an install VBA for ACAD2011 again and look wat's happens.
