安装 Autodesk 产品需要提供产品密钥，这些密钥用于区分单独出售的产品以及作为产品套件的一部分出售的产品。例如，安装单一产品 AutoCAD 2021 时需要产品密钥 001M1，但安装 AutoCAD Design Suite Premium 2021（AutoCAD 设计套件高级版 2021）中的 AutoCAD 2021 时需要产品密钥 768M1。两个软件包中的 AutoCAD 版本相同，但产品密钥不同。
注意：请务必对正在安装的 Autodesk 产品和版本使用正确的产品密钥。如果输入的产品密钥不正确，将导致激活错误。

您可能还需要下载XForce Autodesk XForce 2020 下载（全系产品激活工具）， 以便 激活 您的产品
