如何强制Inno Setup动态设置安装文件夹

问题描述

我正在创建安装软件包，用户应该只能在特定位置安装它.

I am creating an installation package and user should be able to install it on a specific location only.

为此，我在[Code]部分中读取了一些注册表值，以确定安装路径.

In order to do so I read some registry values in the [Code] section to determine the installation path.

具有安装路径后，我需要强制Inno Setup在运行时将安装文件夹设置为特定位置.

Having the installation path I need to force Inno Setup to set the installation folder to a specific location at run-time.

在Inno Setup中有可能吗?如果需要，应该使用脚本的哪一部分?

Is this possible in Inno Setup? Which section of script should be used if so?

谢谢.

推荐答案

• 使用脚本常量设置默认安装路径；
• 使用 DisableDirPage指令以防止用户对其进行修改.
• Use a scripted constant to set the default installation path;
• Use the DisableDirPage directive to prevent an user from modifying it.

[Setup]
DefaultDirName={code:GetDefaultDirName}
DisableDirPage=Yes

[Code]

function GetDefaultDirName(Param: string): string;
begin
  Result := ...;
end;
