In computing, regsvr32 (Register Server) is a command-line utility in Microsoft Windows and ReactOS [1] for registering and unregistering DLLs and ActiveX controls in the operating system Registry. [2] Despite the suffix "32" in the name of the file, there are both 32-bit and 64-bit versions of this utility (with identical names, but in ...
In computing on Microsoft platforms, WoW64 (Windows 32-bit on Windows 64-bit) is a subsystem of the Windows operating system capable of running 32-bit applications on 64-bit Windows. [1] It is included in all 64-bit versions of Windows, except in Windows Server Server Core where it is an optional component, and Windows Nano Server where it is ...
A DWORD value, a 32-bit unsigned integer (numbers between 0 and 4,294,967,295 [2 32 – 1]) (little-endian) 5: REG_DWORD_BIG_ENDIAN: A DWORD value, a 32-bit unsigned integer (numbers between 0 and 4,294,967,295 [2 32 – 1]) (big-endian) 6: REG_LINK: A symbolic link (UNICODE) to another registry key, specifying a root key and the path to the ...
Windows 10 can run on both 32-bit and 64-bit processor architectures. If you have a computer with a 32-bit setup, you can upgrade to the 64-bit version without acquiring a new license.
Mac OS X 10.4.7 and higher versions of Mac OS X 10.4 run 64-bit command-line tools using the POSIX and math libraries on 64-bit Intel-based machines, just as all versions of Mac OS X 10.4 and 10.5 run them on 64-bit PowerPC machines. No other libraries or frameworks work with 64-bit applications in Mac OS X 10.4. [99]
An x86-64 processor acts identically to an IA-32 processor when running in real mode or protected mode, which are supported modes when the processor is not in long mode.. A bit in the CPUID extended attributes field informs programs in real or protected modes if the processor can go to long mode, which allows a program to detect an x86-64 processor.
Older machines that are unable to run the 64-bit kernel run the 32-bit kernel, but, as with earlier releases, can still run 64-bit applications; Lion does not support machines with 32-bit processors. Nearly all applications bundled with Mac OS X 10.7 are now also 64-bit, including iTunes. [citation needed] 2012
The Platform SDK shipped with a compiler that could produce the code needed for these thunks. Versions of 64-bit Windows are also able to run 32-bit applications via WoW64. The SysWOW64 folder located in the Windows folder on the OS drive contains several tools to support 32-bit applications. [22]
