"The old activation key has not been accepted by the license server yet."

客服您好，我购买了
Parallels Desktop for Mac 永久许可证
Parallels Desktop 16 for Mac Standard Edition

也有
Parallels Desktop for Mac 永久许可证
Parallels Desktop 17 for Mac Standard Edition

我的mac安装的是17.但是我输入17的许可证编号，还需要我提供16的激活密钥，我输入后，每次提示"旧激活密钥尚未被许可证服务器接受。"

麻烦帮忙处理一下，感谢您。

 

Customer Service, hello. I have purchased
a permanent license for Parallels Desktop for Mac,
Parallels Desktop 16 for Mac Standard Edition,

as well as
a permanent license for Parallels Desktop for Mac,
Parallels Desktop 17 for Mac Standard Edition.

My Mac is installed with version 17. However, when I enter the license code for version 17, it still requires me to provide the activation key for version 16. After I enter it, I am prompted each time with the message: "The old activation key has not been accepted by the license server yet."

Please help me resolve this issue. Thank you for your assistance.
