This update is only for AutoCAD and AutoCAD LT and cannot be applied to vertical products that are based on AutoCAD 2010.
Installing Update 1 will increment the product version to 2, e.g., "AutoCAD 2010 - English Version 2".
Before installing Update 1, I strongly recommend you review the associated readme file for installation and deployment instructions, information for Windows Vista users, and details about the primary issues that are resolved by Update 1.
Thanks to detailed information from customers who used the Customer Error Reporting (CER) Utility, problems were identified and fixed in more than 30 commands and features. This is a perfect example of why those CER reports are so important and how they help us improve the product.
