问题
As title really. Looking in regedit the key-value exists, but the Wow6432 key (HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion) doesn't have this key. This means a 32-bit app doesn't work on my 64-bit Windows version... which seems wrong, shouldn't the 32-bit app run without modifications? Or is this one case 32-bit apps have to be tweaked to work on 64bit Windows?
回答1:
Applications really shouldn't access this registry value directly. The best way to get this value is to use WMI to get the SerialNumber property of the Win32_OperatingSystem class. This works fine from a 32-bit application running on Win64.
An alternative would be to use the KEY_WOW64_64KEY flag when opening the registry key (does not work on Windows 2000.)
