If you
accidentally delete or alter files that are required by AutoCAD,
AutoCAD might not perform correctly, and you might receive error
messages when you try to execute a command or find a file. You can
attempt to fix this problem by reinstalling or repairing AutoCAD.
The reinstallation or repair uses the features that were part of
the installation type you chose when you initially installed the
program.
To reinstall
or repair AutoCAD
In the Control Panel (Windows), double-click Add or Remove
Programs.
In the Add or Remove Programs window, select AutoCAD 2008, and
then click Change/Remove.
The AutoCAD Installation Wizard re-opens in Maintenance
Mode.
Click Repair AutoCAD 2008.
On the Select Repair or Reinstall page, click one of the
following, and then click Next:
Repair My AutoCAD 2008 Installation.
This option replaces all registry entries that AutoCAD initially
installed and restores AutoCAD 2008 to its default state. If you
are missing AutoCAD files, use this option.
Reinstall My AutoCAD 2008 Installation.
This option repairs the registry and reinstalls all files from the
original installation. Use this option if the Repair My AutoCAD
2008 Installation option does not solve the problem.
On the Repair AutoCAD 2008 page, click Next to start the
process.
On the Repair Complete page, you are informed when the repairs
have been performed. Click Finish.
