I need to install AutoCAD CIVIL 3D 2012 for my class with my 32-bit Windows XP PC. I used CIVIL 3D 2010 before and it works fine. I could not install CIVIL 2012 as I always end up getting Error 1406. How can I fix it? And also, can I use objects that I used in CIVIL 2010 with CIVIL 2012? Are they compatible? I need assistance. Thanks.
