I have recently upraded to AutoCAD Electrical 2014 and keep getting Heidi driver error message, which I've been told is down to the graphics card driver. I am running a 64-bit windows XP machine and have a Nvidia Quadro FX3700 graphics card. Is there a new driver available for it? I have found a "64-bit windows 7 or 8" or a "32-bit windows XP" but cant find the combination I need.
Make sure you do a custom installation and check the box for clean install.
Also, Windows XP support is retiring. If your machine is capable of running XP-64, then it is capable of running Windows 7. You should consider upgrading or buying a new computer before the 2015 release.
