i recently installed acad2005. However, all other users are still using acad 2004 and my program which is developed in 2004. Someone told me that during the installation process of acad 2005, i would be able to keep my acad 2004 library, which it didn't. I went to another computer with acad2004 and copied their acad 2004 library file 'acax16enu'. But if I try to load it in VBA (references), it won't do it. So this means i can't refernce anymore to the acad2004 library. What is the solution to this? Emmanuel
