Slow creation of deployment for AutoCAD® 2008 Civil products
Published date: 2007-04-19

Applies to:
AutoCAD® Civil 3D® 2008
AutoCAD® Land Desktop 2008
Issue
When you created a deployment from the original installation media for AutoCAD® Civil 3D® 2008, AutoCAD® Civil 3D® – Land Desktop Companion 2008, or AutoCAD® Land Desktop 2008, it took much longer than expected.
Solution
The new installer for these products incorrectly copies the data from the installation media to the destination folder multiple times, increasing the deployment creation time considerably.
To avoid this issue, it is strongly recommended that you copy the installation files to a local drive first and then run the installer on the local drive to create the deployment
