The AutoCAD 2004 Service Pack 1A and the AutoCAD LT 2004 Service Pack 1A should be applied
on all supported operating systems and languages. There are separate service packs for the
locked and unlocked versions. The service pack is required for any AutoCAD® 2004 extensions.
Please see the Readme file for each service pack for a summary of the primary issues they
resolve.
Note: If you want to use the Autodesk Network Installation wizard to deploy AutoCAD 2004
Service Pack 1A, you must download and run the Autodesk Network Installation Wizard patch.
For more information about this patch, see the associated Readme file.
If you use the Live Update feature in Communication Center, the service pack version that
you need is automatically identified. If you have the same product in multiple languages,
all applicable versions will be patched. Separate patches are needed for locked and unlocked
versions.
If you download the service pack manually, download and install the locked version of the
service pack if you are using:
An educational or trial version of AutoCAD 2004 or AutoCAD LT® 2004
The International English version of AutoCAD 2004
Download and install the unlocked version of the service pack in all other instances.
