Reinstalling AutoCAD Civil 3D Land Desktop Companion 2009

Before you reinstall AutoCAD Civil 3D Land Desktop Companion 2009, delete the contents of your Windows Temp folder. If you are working with Windows 95, Windows 98, or Windows Me, your Windows Temp folder will typically be found in the C:Windows directory. If you are working with Windows NT 4.0, Windows 2000, or Windows XP, your Windows Temp folder will typically be found in the C:Documents and Settings<user>Local Settings directory.

You should also close and temporarily disable any antivirus software that may be running on the system. You can use the End Task feature to close the antivirus software. Disabling the software from the system tray may not be sufficient. Antivirus software may block certain activities (for example, access to the registry, adding, removing, or updating DLL files, and so on) that are seen as suspicious, even though these activities are common when installing or removing programs. Several antivirus programs can be disabled by right-clicking their taskbar icon, and then clicking Disable on the shortcut menu. For more information about disabling your antivirus software, refer to the software vendor.

To verify that an antivirus program is not running in the background as a TSR (Terminate and Stay Resident program)

In Window 95, Windows 98, and Windows Me:

1. Press CTRL+ALT+DELETE.
2. In the Close Programs window, select the antivirus program and click End Task.

In Windows NT, Windows 2000, and Windows XP:

1. Press CTRL+ALT+DELETE.
2. Click Task Manager.
3. In Task Manager, click the Processes tab.
4. On the Processes tab, select the antivirus process, and then click End Process.

Now, you can reinstall AutoCAD Civil 3D Land Desktop Companion 2009 on the computer.
