Refer to (VS.85).aspx WOW64 is the x86 emulator that allows 32-bit Windows-based applications to run seamlessly on 64-bit Windows. Net Runtime in 64-bit checking, instead of Windows OS?ĭear all, seems already figured out the answer of the question. Consider the following code snippet: public void SizeOfIntPtr() When run on a 32-bit platform you will get the following output on the console: SizeOf IntPtr is: 4 On a 64-bit platform you will get the following output on the console: SizeOf IntPtr is: 8 Note If you want to check at runtime whether or not you are running in a 64-bit environment, you can use the IntPtr.Size as one way to make this determination. NET there is an integral data type, not widely known, that is specifically designated to hold 'pointer' information: IntPtr whose size is dependent on the platform (e.g., 32-bit or 64-bit) it is running on. NET CLR for 64-bit platforms uses the same LLP64 abstract data model. Net framework is x86 or 圆4 version? Refer to The. Still a bit confused, pls let me repharse the question, how to check the installed. So, definitey, the answer is 64bit version of the dependencies should be choosed in 64-bit Windows. After checked the server directory, indeed both x86 and 圆4 versions are installed on 圆4 machines (check out the Microsoft.NET folder under %WINDIR%, you should find both Framework and Framework64.

Refer to displaylang=en&displaylang=en NetFx20SP2_圆4.exe 46.3 MB NetFx20SP2_x86.exe 23.8 MB 圆4 package is almost double size of the x86 version, such that I guess it's also includes x86 version, as 32-bit app also supported via WOW64 in 64-bit Windows. WOW64 is provided with the operating system and does not have to be explicitly enabled. Dear all, seems already figured out the answer of the question.
