如何确定我要安装的应用程序是32位还是64位？ [英] How do I determine whether an application I am installing is 32-bit or 64-bit?

问题描述

我希望能够预测应用程序的默认安装位置。在64位计算机上，如果它是32位应用程序，则将安装在程序文件（x86）中；如果是64位应用程序，则它将安装在程序文件中。

我的目标是使用默认位置安装应用程序，并验证安装是否正确。但是为此，我需要知道它将安装在哪里。如果我知道构建该应用程序所基于的体系结构，那么我认为它将满足我的目的。

I want to be able to predict the default install location of an application. On a 64-bit machine, if it is a 32-bit application, it would install in "Program Files (x86)" and if it were a 64-bit application, it would install in "Program Files".

My goal is to install the application with its default location and validate if the install was fine. But for this I need to know where it would be installed. If I know what architecture the application is built for, I think it would serve my purpose.

解决方案

If you can use external tools then GNU file is the most versatile solution. But it might be a bit overkill for this purpose. Other alternatives being Dependency Walker, Sysinternals' Sigcheck, MSVC's dumpbin or corflags... But the one that might surprise a lot of people is 7zip. It has a small file-like utility inside that can be used with l option

C:\>7z l "C:\Program Files (x86)\Windows Photo Viewer\ImagingDevices.exe" | findstr CPU
CPU = x86

C:\>7z l "C:\Program Files\Windows Photo Viewer\ImagingDevices.exe" | findstr CPU
CPU = x64

If you have to check it yourself then read 2 bytes at offset 0x3C in the file. Then add 4 to this value and read 2 bytes at that offset, that'll indicate the architecture. For example in the below example the file contains 0x00E0 at offset 0x3C. At offset 0x00E0 + 4 = 0x00E4 contains 0x8664 which means a 64-bit binary. If it was a 32-bit x86 binary then it will contain 0x014C

There are more ways that you can find in the below links. There are also other PowerShell and VBS scripts available for that purpose
