如何在应用Visual Studio 2015后更改产品许可证密钥？ [英] How change product license key of Visual Studio 2015 after it is applied?

问题描述

我需要更改我当前安装Visual Studio 2015的产品许可证密钥。

在菜单帮助，注册产品中我没有链接"更改我的产品许可证。相反，我只有"许可证：应用了产品密钥"。

但是，我需要更改密钥，因为我当前的安装不使用好密钥。 

我已经重新安装但是没有用。

你能帮助我吗？

解决方案

嗨Dorileo，

欢迎使用MSDN论坛。

您可以采取以下步骤更改产品密钥：

1. 删除注册表项 HKEY_CLASSES_ROOT \LICenses\4D8CFBCB-2F6A-4AD2-BABF-10E28F6F2C8F
2. 删除此密钥后，Visual Studio 2015会告诉您它的许可证信息不正确。转到"程序和功能"和
   修复 2015年视觉工作室。
3. 修复后，visual studio 2015将恢复为30天的试用期，您可以输入一个新的产品密钥。
   

如果找不到注册表项，请使用Process Monitor找到注册表项。

从

启动Visual Studio 2015后，您可以在Process Monitor中搜索"许可证"或"许可证"关键字，以查找Visual Studio 2015的注册表项。

祝你好运，

Hi, I need to change the product  license key of my current instalation of Visual Studio 2015.
In the menu Help, Register Product I have not a link "Change my product license. Rather, I have only "License: Product key applied".
However, I need to change the key because my current instalation is not using the good one. 

I've already reinstalled but it didn't work.

Could you help me?

解决方案

Hi Dorileo,

Welcome to MSDN forum.

You could take the following steps to change the product Key:

1. Remove registry key HKEY_CLASSES_ROOT\Licenses\4D8CFBCB-2F6A-4AD2-BABF-10E28F6F2C8F
2. After you remove this key, visual studio 2015 will tell you that it's license information is incorrect. Go to "Programs and features" and repair visual studio 2015.
3. After the repair, visual studio 2015 is reverted to a 30-day trial and you can enter a new product key.

If you couldn’t find the registry key, please use Process Monitor to find the registry Key.

Download Process Monitor from http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx.

After launching visual studio 2015, you could search the "Licenses" or "License" keywords in Process Monitor to find the registry key for visual studio 2015.

Best regards,

Joyce
