As you may already knew, zune software only supports English version Windows XP/Vista. Then how to install zune software on non-English version Windows?
Here it goes:
For Windows XP:
1. Download and install MSXML6 for your language of Windows XP.
2. Download and install zune 1.0 (which did not check Windows language and ZuneSetup.exe execution).
Note: Download both files from the above links, and extract it by using WinRAR.
3. Launch zune software and update it.
For Windows Vista:
Since zune 1.2 is the only version that supports Windows Vista, we cannot use the same method mentioned above. What’s worse – zune 1.2 checks system language and ZuneSetup.exe execution.
For now, the only workaround is install en-us MUI for Windows Vista. The steps are:
1. Install Windows Vista EN-US MUI.
2. Change your user account to use English as your language.
3. Go to http://www.zune.net, download and install ZuneSetup.exe.
4. Complete the installation.
5. After that, you can switch back your language to non-English one.
However, please note – ONLY Enterprise and Ultimate version of Windows Vista can install MUI.

也许大家都知道zune软件只支持英文版的Windows XP/Vista。那么如何安装zune到非英文版系统呢？
Windows XP步骤：
1. 下载并安装适合您的语言版本Windows XP的MSXML6。
2. 下载并安装zune 1.0（该版本不会检测系统语言和ZuneSetup.exe是否执行）。
注意：请下载以上链接中的两个文件，并用WinRAR解压缩。
3. 运行zune软件，进行版本更新。
Windows Vista步骤：
由于zune 1.2是唯一支持Windows Vista的版本，我们不能使用以上步骤来完成安装。更糟糕的是zune 1.2检查系统语言以及ZuneSetup.exe是否执行。至今唯一的解决方案便是安装Windows Vista英文MUI（多国语言界面）。步骤如下：
1. 安装Windows Vista英文MUI。
2. 改变您的用户使用英文语言。
3. 访问http://www.zune.net ，下载并安装ZuneSetup.exe。
4. 完成安装。
5. 最后，您可以将语言重新转换为非英语即可。
但是，请注意——只有Enterprise和Ultimate版本的Windows Vista才可以安装MUI。
