AutoCAD 2011 for Mac: Update Beta for OS X Lion
Inventor 2012 GPO deployment, Windows 2003 Server, Error Add operation failed

AutoCAD Family: Unhandled Exception in acmgd.dll ARX Command

Unhandled Exception errors are one of the toughest things to troubleshoot.  The good thing is that we have a solution for:

  • Unhandled Exception E0434F4D (e0434f4dh) at address 7c81EB33h
  • Unhandled Exception E0434352 (e0434f4dh) at address 7c81EB33h

Civil3d-1-error - Copy


We had to add Read and Read & Execute to the group Users and/or Everyone for the following files:

Windows XP/Vista/7 x86 (32 bit)

C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config

Windows XP/Vista/7 x64 (64 bit)

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG\machine.config

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config

I had to update this reference post as well.

Epilogue

If you have the same product installed on serveral computers and the error happens only on 1 computer, you can copy the folders above from a working computer to an non-working computer to easily transfer the proper permissions.

Thanks to John Lee for sharing this additional tip with the community.

Do I understand then Microsoft.net version 4 has to be installed prior to installation of Civil 3D 2012? I did not see that option on the installation disk. Thank you.
