Issue:

When starting AutoCAD, the splash screen pauses on 'checking license' for more than a minute when the computer is connected to the internet. When there is no internet, AutoCAD opens in under 20 seconds.

Causes:

Antivirus is slowing down AutoCAD's license check. 

Solution:

Try one of the following:
  • Adding these Antivirus exceptions:
    • C:\Program Files\Autodesk
    • C:\Users\<user>\AppData\Roaming\Autodesk
    • C:\Users\<user>\AppData\Local\Autodesk
  • Also, creating exceptions for the various types of files used by Autodesk products can be helpful.  Here is a list of some file types used by Autodesk programs:
    • 3ds, ac$, apj, bak, ctb, cui, cuix, dcl, dst, dwf, dwg, dwl, dwl2, dwt, fbx, ipt, lin, ma, mat, max, mb, mns, mnu, pat, pgp, rfa, rft, rte, rvt, shp, shx, stb, sv$
  • The following may also be needed:
    • .sq* (sqlite), .wdp, .ldb, .mdb, .mui, .aux, .chm
  • If you are using AutoCAD Electrical, add an exception to the Acade folder in Documents:
    • C:\Users\<user>\Documents\Acade 201x
