FATAL ERROR: Unhandled Access Violation Writing 0xf1ffadb3 Exception at f1ffadb3

[BrendonDoughty]

Hello everyone, I'm Brendon and I hope you can help.

I've recently installed the 2017 Autocad LT and after having a couple of problems i went through and installed the various hotfixes and updates that were available and all seemed well, i've had no trouble all week since.

I came back from a site visit today and upon opening Autocad i received this error message (a splash crash i think they call it)

The code itself is different each time and i notice it states "violation writing" where most topics i've seen posted state "violation reading"

Can any body help with this?

I've gone through other topics and tried a few suggestions to no avail, theres been no updates or changes to the computer that i'm aware of ...

Many thanks,

Brendon

Hello @BrendonDoughty.

There are several ways to troubleshoot the problem:

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.
  See: How to create a new local administrator Windows user account

• If DisplayLink Core software is installed on your system, try uninstalling it.

• Do a full uninstall and reinstall of AutoCAD.
  See:  Remove All Products from a Windows System

• Uninstall and reinstall the .NET Framework.
  See: How to remove and reinstall the Microsoft .NET Framework

• Uninstall and reinstall Visual C++.
  See: How to remove and reinstall Microsoft Visual C++ Runtime Libraries

• Clear the digital signature icons and then uninstall and reinstall the application.

Thank you for these solutions,

I will start working my way through them and let you know the outcome. 

Is it worth stating that my autocad 2016 comes up with the same Fatal error message, but on another computer on the network the autocad is working fine. 

Cheers Brendon

Upon trying to access the control panel other programmes the computer started to play up, not opening files etc so I tried the faithful switch it off and switch it on again which seems to have solved the problem for now. Thank you for these points , i'll keep them bookmarked if a problem arises again.
