Solution: Fatal error when launching AutoCAD

Solution:

There are several ways to troubleshoot the problem:

• Update the product.
  Updates for latest releases are acquired via the Autodesk Desktop App. Right-click its icon down on the status bar next to the time and pick “Check now.” You may also download updates through your Autodesk Account (see How to Access Product Updates in Autodesk Accounts). For older products, see Autodesk Downloads.
• Try opening another drawing.
  If you can open another drawing, the original drawing may be corrupt and require repair.
  See: How to repair corrupt AutoCAD files
• Uninstall any antivirus or desktop locking programs.
  These programs can cause errors in AutoCAD, since they prevent the system environment from working.
• Reset AutoCAD to defaults.
  See: How to reset AutoCAD to defaults
• Turn off Hardware Acceleration.
  See: Starting AutoCAD-based products without hardware video acceleration
• Update your graphics driver.
  Install the latest graphics driver from your video card manufacturer or use an AutoCAD-certified driver.
  See: How to update your system to the latest certified video driver
• Try logging in under a new Administrator Windows Account.
  If you create a new account and can successfully open the drawing, you can either use that account or rebuild the user profile in Windows.
