The problem seems to be caused by an old bug that was fixed in Windows XP but is apparently unpatched in my Windows 7. From http://support.microsoft.com/kb/929863:
该问题似乎是由 Windows XP 中修复的旧错误引起的，但在我的 Windows 7 中显然未修补。来自http://support.microsoft.com/kb/929863：
This problem occurs because of a limitation in the ExecCommandfunction. When you run the script that uses the ExecCommandfunction together with the SaveAscommand, the script can only save a file that is the text file type.
由于ExecCommand函数中的限制，会出现此问题。当您运行同时使用ExecCommand函数和SaveAs命令的脚本时，该脚本只能保存文本文件类型的文件。
Sure enough, change the file extension to ".txt" and watch it magically work in IE8.
果然，将文件扩展名更改为“.txt”，然后在 IE8 中观看它神奇地工作。
The only workaround that comes to mind is to have a server-side language create the CSV file, and serve it up as a download (using the Content-disposition: attachmentheader).
想到的唯一解决方法是让服务器端语言创建 CSV 文件，并将其作为下载（使用Content-disposition: attachment标题）提供。

I know this is an very old thread, but I also faced this problem. You can fix it by adding the following value (depending on the extension of the file beeing downloaded) to your registry.
我知道这是一个非常古老的线程，但我也遇到了这个问题。您可以通过将以下值（取决于正在下载的文件的扩展名）添加到您的注册表来修复它。
E.g. for .csv file:
例如对于 .csv 文件：
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.csv]
"PerceivedType"="document"
@MICROSOFT: Shame on you; problem seems to be still unpatched :-)
@MICROSOFT：为你感到羞耻；问题似乎仍未解决:-)

If you could do this processing server side with PHP or .NET or Java or something, in the http headers set:
如果您可以使用 PHP 或 .NET 或 Java 或其他东西来处理服务器端，请在 http 标头集中：
Content-Disposition: attachment; filename=file.csv
Which, unfortunately you can't do from JavaScript.
不幸的是，您不能从 JavaScript 中做到这一点。
