为32和64位应用程序启动正确的安装程序 [英] launching correct installer for 32 and 64-bit apps

问题描述

我们有一个应用程序，由于各种原因，该应用程序需要同时编译为32位和64位应用程序。问题是，我们要将两个安装文件（msi）都分发到一张CD中。是否存在启动条件或autorun.inf条目，我们可以用来了解要启动哪个setup.exe？还是我们需要编写一个单独的小exe文件，该文件会被autorun调用，并确定操作系统并调用相应的setup.exe？

We have an application which, for various reasons, needs to be compiled as both a 32-bit and 64-bit app. The thing is, we want to distribute both setup files (msi) on a single CD. Is there a launch condition or autorun.inf entry that we can use to know which setup.exe to launch? Or do we need to write a separate little exe that gets called by autorun, and which determines the OS, and calls the appropriate setup.exe?

推荐答案

在 autorun.inf文件。

大多数提供32位和64位MSI的应用程序都遵循的约定类似于您提到的第二个选项。

The convention that most applications which supply a 32 and 64 bit MSI follow is similar to the second option you mention.

1. 创建一个32位setup.exe应用程序（以便它可以在任一平台上运行）。理想情况下，这将使用C / C ++编写，以使其尽可能小巧，快速，并且不依赖于其他库/框架（例如静态链接）。


2. 检测是否在64位上运行（请参阅Windows API示例代码 IsWow64Process 函数


3. 执行适当的MSI

1. Create a single 32bit setup.exe application (so that it will run on either platform). Ideally this will be written in C/C++ so that it is as small and quick as possible, and has no dependencies on other libraries/frameworks (eg. static linked).
2. Detect if you are running on 64bit or not (see sample code for Windows API IsWow64Process function
3. Execute the appropriate MSI
