在Inno安装命令行中使用DIR开关

Question

我创建了这个简单的脚本：

[ISPP]
; SignTool parameters
#define SignedDesc "$qxxx$q"
#define SignedPfx "$qxxx$q"
#define SignedTimeStamp "$qhttp://timestamp.verisign.com/scripts/timestamp.dll$q"
#define SignedPw "$qxxx$q"

#define AppURL "http://www.publictalksoftware.co.uk"
#define AppPublisher "Andrew Truckle"

通知？它为什么要将其安装到Windows文件夹中？

2019-05-31 21:32:03.360 Dest文件名:c:\windows\communitytalks.chm

我如何指定我真正想要安装文件的文件夹？

Source: "CommunityTalks.chm"; DestDir: "{param:InstallPath}"; Flags: ignoreversion

// Returns the path where the program was last installed
function GetPathInstalled( AppID: String ): String;
var
    sPrevPath: String;
begin
    sPrevPath := '';
    if not RegQueryStringValue( HKLM,
        'Software\Microsoft\Windows\CurrentVersion\Uninstall\'+AppID+'_is1',
        'Inno Setup: App Path', sPrevpath) then
        RegQueryStringValue( HKCU, 'Software\Microsoft\Windows\CurrentVersion\Uninstall\'+AppID+'_is1' ,
                            'Inno Setup: App Path', sPrevpath);

    Result := sPrevPath;
end;

引用createappdir文档：

如果将此设置为否，则不会为应用程序创建任何目录，也不会显示选择目标位置向导页，并且{app}目录常量等效于{win}目录常量。
