在一个主许可下面添加一个新的主机ID错误

公司已经购买了一系列的Polyspace产品,包括Polyspace Bug Finder Server,Polyspace Bug Finder Server,Polyspace as You Code, Polyspace Access。但之前购买的Polyspace Access都是在一台Windows服务器(MAC地址,Host ID为A)上激活的,所以我们主许可证都是在注册在Host ID A上。但是我们有一台Linux Ubuntu的服务器(MAC地址,Host ID为B)需要一个运行在Linux上的Polyspace Access。于是我们新购买了一个Polyspace Access License (许可证编号41233541)。购买成功我在许可证中心激活该License时输入Host ID B时,激活不了。显示“错误
没有更多激活可用。您可能需要先反激活先前已激活的计算机,然后才能激活此计算机。有关更多详细信息,请参阅此答复。如果您执行的是网络客户端安装,请参阅此技术解答。”
Our company has purchased a suite of Polyspace products, including Polyspace Bug Finder Server, Polyspace as You Code, and Polyspace Access. Previously, the Polyspace Access licenses were activated on a Windows server (with MAC address/Host ID "A"), so our primary licenses are registered to Host ID A. However, we now have a Linux Ubuntu server (with MAC address/Host ID "B") that requires an instance of Polyspace Access running on Linux. Consequently, we purchased a new Polyspace Access license (License ID 41233541). When I attempted to activate this new license in the License Center using Host ID B, the activation failed. The system displayed the following error: "Error: No more activations available. You may need to deactivate a previously activated machine before activating this one. Please refer to this answer for more details. If you are performing a network client installation, please refer to this technical solution."

Hello Zheng,
You can Go to the MathWorks License Center to see whether the license has already been activated on another machine and requires deactivation before reuse. The error message itself suggests that no remaining activations are available.
To deactivate MATLAB from the MathWorks License Center:
  1. Go to the MathWorks License Center.
  2. Select the license you want to deactivate.
  3. Select the "Install and Activate" tab.
  4. If the activation list isn't already displayed, select "View Current Activations" from the Related Tasks section.
  5. Under the last column, "Deactivate," click the blue X in the row of the activation you wish to deactivate.
You can also verify whether the correct Host ID is being used for the Linux machine. For that you can refer to the these instructions.
If the issue still remains unresolved, you can reach out to MathWorks Installation Support.
