I had quite an issue on a machine that I had installed AutoCAD 2014 on multiple times, but every time I tried to fire it up I would get this "Display driver file is missing or corrupted" error. Then AutoCAD would crash.
I copy pasted drivers and files from a working machine but nothing. Then I thought, "I have been having issues with hardware acceleration".
I added this switch "/nohardware" to the start up icon, and wa-shaw! no worries.
I am looking into which drivers, video cards, and yadda, yadda, but at least now we can fire up this machine and draft things.
Back to business people.
