VBA references

[NirantarVidyarthee]

I have AutoCAD 2011 2012 & 2013 installed. All are needed for various reasons.

The problem is, when start a new project AutoCAD 2012 library is automatically referenced. Even if I try to remove it, AutoCAD does nor allow it saying that it is in use. I can't even find AutoCAD 2011 library in the list of references. And I want to reference 2011 library only.

There is not a different type libary for every version of AutoCAD for example

AutoCAD 2010 and 2011 use the same type library version V18.

I believe AutoCAD 2013 is a new type library.
