不管你信不信,我安装程序太旧,它并没有一个选项,以检测64位版本的Windows。
Believe it or not, my installer is so old that it doesn't have an option to detect the 64-bit version of Windows.
有一个Windows DLL调用或(甚至更好)的环境变量,这将使该信息的Windows  XP和Windows  Vista的
Is there a Windows DLL call or (even better) an environment variable that would give that information for Windows XP and Windows Vista?
一个可行的办法
我看到维基百科指出,64位版本的Windows&NBSP的; XP和Windows  Vista中有一个独特的环境变量:%ProgramW6432%
,所以我猜这会是空的32位Windows。
I see that Wikipedia states that the 64-bit version of Windows XP and Windows Vista have a unique environment variable: %ProgramW6432%
, so I'm guessing that'd be empty on 32-bit Windows.
该变量指向程序文件
目录,它存储的Windows和其他的所有已安装的程序。在英文系统默认为 C:\ Program Files文件
。在Windows(XP,2003,Vista)的64位版本,也有的%ProgramFiles(x86)的%
默认为 C:\ PROGRAM文件(x86)
和%ProgramW6432%
默认为 C:\ Program Files文件
。该的%ProgramFiles%
本身取决于请求环境变量的过程本身是否是32位或64位(这是由于Windows的在Windows的64位重定向)。
This variable points to Program Files
directory, which stores all the installed program of Windows and others. The default on English-language systems is C:\Program Files
. In 64-bit editions of Windows (XP, 2003, Vista), there are also %ProgramFiles(x86)%
which defaults to C:\Program Files (x86)
and %ProgramW6432%
which defaults to C:\Program Files
. The %ProgramFiles%
itself depends on whether the process requesting the environment variable is itself 32-bit or 64-bit (this is caused by Windows-on-Windows 64-bit redirection).
见的的如何检查如果计算机运行的是32位或64位操作系统 的。它还包括从注册表检查这说明:
See the batch script listed in How To Check If Computer Is Running A 32 Bit or 64 Bit Operating System. It also includes instructions for checking this from the Registry:
您可以使用下面的注册表位置来检查,如果计算机运行的是32位或64位Windows操作系统:
You can use the following registry location to check if computer is running 32 or 64 bit of Windows operating system:
HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0
您将看到在右窗格中以下注册表项:
You will see the following registry entries in the right pane:
Identifier REG_SZ x86 Family 6 Model 14 Stepping 12
Platform ID REG_DWORD 0x00000020(32)
上面的x86和0x00000020(32)指示该操作系统的版本是32位
The above "x86" and "0x00000020(32)" indicate that the operating system version is 32 bit.
