In the past I have always had two versions of AutoCAD installed on my system. One for straight AutoCAD work and the other for Archibus CAD Overlay work. Last time I did this I had AutoCAD 2010 and AutoCAD 2009 installed.
Now that Autodesk has changed their educational licensing and our facilities department no longer qualifies for educational pricing (we now get government pricing) I have to do some new installs. I have to do new installs of AutoCAD because I got a brand new CPU. I installed AutoCAD 2015 and when I went to install AutoCAD 2014 (I even Specified a separate directory for the install then the 2015 directory) the program booted me out saying I have to uninstall 2015 before I install 2014.
Does anyone know a work around? Should I have installed 2014 before 2015? Should I try and even older version (I can go back as far as 2012)? Should I just become Amish and forget about all technology?
