我怎样才能检查我的X64 Pc上安装了哪个Office Bitness
问题描述：
作为标题，我需要知道我的x64电脑上安装了哪个办公室位。
我检查了regedit并且没有找到任何提示。
也许我可以找到安装路径，并检查pe头，但它很复杂，我想检查NSIS脚本，所以越容易越好。
有什么提示吗？非常感谢。
as the title,I need to know which office bitness installed on my x64 pc.
I checked regedit and did not find any tip.
Maybe I can find the install path, and check the pe header, but it's Complicated, I want check in NSIS script, so the easier the better.
Any tips? thanks a lot in advance.

如果可执行文件（winword.exe，excel.exe，outlook.exe等）位于％SystemDrive％中\Program Files，你有64位版本。
如果它们位于％SystemDrive％\Program Files（x86）中，你正在处理32位版本。
干杯。
的确，如果改变标准安装路径，这种方法赢了工作。
根据 SO：如何以编程方式检测32位或64位visio版本？ [ ^ ]，你还有更多的选择：
- 您可以在注册表中检查 HKLM \所以是否存在相应的密钥ftware \ Microsoft &\\Office （64位）或 HKLM \Software \Wow6432Node\Microsoft \ Office （32 -bits）
- 你可以使用 GetBinaryType函数 [ ^ ]
[/ Edit]
If the executable files (winword.exe, excel.exe, outlook.exe, etc.) are located in "%SystemDrive%\Program Files", you have the 64-bits version.
If they are located in "%SystemDrive%\Program Files (x86)", you are dealing with the 32-bits one.
Cheers.
Indeed, if standard installation path is changed, this method won't work.
According to SO: How to programmatically detect 32-bit or 64-bit visio version is installed?[^], you have some more options:
- you can check in the registry whether corresponding keys exist in HKLM\Software\Microsoft\Office (64-bits) or HKLM\Software\Wow6432Node\Microsoft\Office (32-bits)
- you can use the GetBinaryType function[^]
