AutoCAD Civil 3D 2010 Update 3 was released today, addressing a number of known program issues. I know some of you are hesitant to apply these updates but they are important and typically required to avoid stalling the support process.
As always, backup all program customizations to a secure location before installing the update. Then import and reapply after the update has been successfully installed.
If you intend to install the AutoCAD Civil 2010 Subscription Advantage Pack do so before applying the update or the installation will fail.
You must have administrative privileges to install the update. You may be prompted for the original installation media or network image. The update can be deployed over a network using the Deployment Wizard.
You cannot uninstall this update. Civil 3D 2010 must be uninstalled/reinstalled to restore it to pre-update condition.
