I get a fatal error unhandled e0434352h exception at 7c812afbh when 2012 loads up. This is a  new upgrade I just downloaded. Any help on resolving this issue will be greatly appreciated.

Typically this error has to do with a problem in your Microsoft .NET Framework.  You probably need to uninstall older versions and reinstall .NET Framework 3.5 SP2 and/or .NET Framework 4.0.

I'm getting the same error.  I've tried every "solution" I could find online but no luck.  Were you able to resolve this?

Beside corrupted .NET, often times this error could also relate to inadequate graphics cards/drivers for ACAD 2012.


You can check your video card and video drivers against Autodesk Certified Graphics Hardware list.

 

in many cases disabling hardware acceleration can help with this error.

1. Right-click the ACAD 2012 icon on your desktop > Properties
2. By default the Target is: " "C:\Program Files\Autodesk\AutoCAD 2012 - English\acad.exe"”
3. Add a space and then /nohardware at the end, so the new Target would be:

 "C:\Program Files\Autodesk\AutoCAD 2012 - English\acad.exe"" /nohardware
4. Apply > OK > launch ACAD 2012

Hi,

 

Thanks for the suggestion but the error still persists.  Since this version of AutoCAD works for another user with the exact same hardware the video card doesn't appear to be the issue.

You need to use the .NET Framework cleanup tool, then reinstall .NET Framework and repair AutoCAD.  This is a known issue.

.NET Framework issues can be resolved using the .NET Framework Cleanup Tool. More information about this tool can be found at my discussion thread here:

Good Luck!
