https://knowledge.autodesk.com/zh-hans/customer-service/download-install/activate/find-serial-number-product-key/product-key-look/2021-product-keys

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：请确保为正在安装的 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，将导致产品出现激活错误。
