Question

Noob问题！

所以到目前为止我已经编写了这段代码

Example:
var query = { fields: {password: false} }
Model.find(query, function()
{
});

这些适用于学校计算机，因此我希望用户能够在他们选择的文件夹中安装exe。（学校限制C盘）我试过了

但拒绝工作：（（安装程序工作正常，只是我不能选择我的目录）请告诉我我做错了什么！提前谢谢！

Answer 1

$InstDir属性在执行任何代码之前安装程序启动时初始化StrCpy $InstDir "c:\some\new\path"变量。

如果您想允许最终用户更改安装目录，那么您通常会添加目录页面，但您也可以在自定义页面或InstFiles页面之前的任何其他位置执行此操作;只需使用类似File的内容。

在使用SetOutPath指令提取文件之前，必须使用File指令。它创建目录并设置OutFile "MySetup.exe" InstallDir "$ProgramFiles\MyApp" ; $InstDir default value RequestExecutionLevel Admin Page Directory ; This page might change $InstDir Page InstFiles Section SetOutPath "$InstDir" ; This basically does StrCpy $OutDir $InstDir + CreateDirectory $OutDir File "MyApp.exe" ; This will extract as "$OutDir\MyApp.exe" SectionEnd指令的目的地。

最小安装程序可能如下所示：

SetOutPath

您的示例代码在自定义欢迎页面中调用$InstDir，此时InstallDir只有SetOutPath的值，之后您再也不会再调用html,body { width: 100%; height: 100%; margin: 0px; padding: 0px; overflow-x: hidden; }。< / p>

Answer 2

您需要为选择对话框指定其他Page：

Page directory
Page instfiles

请注意，声明这些网页的顺序非常重要，通常instfiles会持久。

我需要设置我的安装目录
