我遇到了这个自定义操作的问题，我还没有看到一个比运行文件更复杂的例子。
我已经读过这篇文章，但没有考虑额外的参数： http://wix.sourceforge.net/manual-wix3/qtexec.htm
在看到引用接收此错误的内容后，我设法让这个不要抱怨。我不确定为什么，但命令可以复制并粘贴到命令窗口。
任何人都知道为什么这在静音CA中不起作用？
干杯， Ĵ

你应该把aspnet_regiis的完整路径放到引号中，如下所示：
<CustomAction Id="SetMyAction" Property="MyAction" Value=""[NETFRAMEWORK40FULLINSTALLROOTDIR]aspnet_regiis.exe" -s
W3SVC/1/ROOT/ConfigurationWebService"/>
其中[NETFRAMEWORK40FULLINSTALLROOTDIR]包含aspnet_regi所在文件夹的完整路径，以反斜杠结尾。此属性在WiXNetfxExtension。
