Note that SysWow64 means “Windows On Windows” – and thus allows a process to run in a 32-bit 64-bit OS.
The 圆4 DLLs are usually located in C:\Windows\System32 The x86 DLLs are usually located in C:\Windows\SysWow64 Some facilities may be different, which complicates the task – you can use Task Manager to see if your process is 32-bit or 64-bits. So I will call “ x86” or “ 32-bit” any process or DLL 32-bit – and “ 圆4” or “ 64-bit” or process any 64-bit DLL.Ī process x86 is usually installed in C :\Program Files (x86) or C:\Windows\SysWow64Ī process 圆4 is usually installed in C:\Program Files or C:\Windows\System32
First, we’ll start with some naming conventions with the basic premise that we are on a 64-bit Windows operating system (XP, Vista, 2003, 2008, 7).
