Answer: To install a 32-bit application on a 64-bit processor that uses the x86-x64 instruction set, you should simply run the 32-bit installation file for the application on the computer. The operating system will be able to run the 32-bit application using the WOW64 (Windows 32-bit on Windows 64-bit) emulation layer, which is included with most modern versions of Windows.
Explanation: The fact that the computer has a dual-core processor does not affect the installation of the 32-bit application. However, it is worth noting that a 64-bit operating system running on a dual-core processor can potentially take advantage of the additional processing power and memory available in the processor.
