无法激活 Parallels Desktop:许可证服务器未接受 Parallels Desktop 早期版本的产品密钥

我在2016年购买了Parallels Desktop 12.
因为我的上一台MAC在2018年丢失，更换新的电脑之后我从未安装Parallels Desktop 12.
今天我尝试在新的电脑上安装Parallels Desktop 12.
我在邮箱里找到了当时购买的注册码，我输入之后，提醒我这是一个升级注册码，需要我填写老的码.我在邮箱中找到了一串老的码（邮箱里告诉我说，有时候注册可能需要这个老的码）。
当我填写了两个注册码，仍然提示我：
无法激活 Parallels Desktop:许可证服务器未接受 Parallels Desktop 早期版本的产品密钥

现在我需要解决这个问题，究竟是哪一个注册码错误？我该如何注册？

I purchased Parallels Desktop 12 in 2016.
Because my last MAC was lost in 2018, I never installed Parallels Desktop 12 after replacing it with a new mac.
But today I tried to install Parallels Desktop 12 on a new computer.
I found the registration code purchased at the time in the mailbox. After entering it, I was reminded that this is an upgrade registration code, which requires me to fill in the old code. I found a series of old codes in the mailbox and the mail said Sometimes registration may require this old code).
When I filled in two registration codes, I was still prompted:
Unable to activate Parallels Desktop: the license server did not accept the product key of the earlier version of Parallels Desktop

Now I need to solve this problem. Which registration code is wrong? How do I register?
