After starting AutoCAD 2014 64-bit on my office computer for the first time in a while, I ran in to a little issue. I was greeted by a “Display driver file (.HDI) is missing” error and AutoCAD 2014 would not start.
I tried a repair and re-installation of AutoCAD 2014 without success. Then I remembered a basic troubleshooting type I ask everyone, “What has changed?” The video card changed, that would explain why I am having issues with the Heidi video card driver in AutoCAD 2014. So I downloaded the latest version of the FirePro driver from ATI and wouldn’t you know it AutoCAD 2014 started working again.
Moral of the story:
- Always ask and answer yourself with the last thing that has changed. You don’t need to lie and say “nothing”, because you know better.
- When you change hardware like a video card, install the driver even if Windows 8 sees the card.
