Discussion - Can I run a 64-bit application on a 32-bit operating system?

So far, there seems to be a lot of "freaking out" between choosing 32 or 64 bit operating systems for their computers and laptops! TipsMake.com has many articles on this issue, you can refer to details in the link below. However, besides, there are some questions raised by the user community, such as:

1. Can I run a 64-bit application on the OS platform - OS 32 bit?
2. And is there a program, some simulator that helps me do that?

In the article below, please join TipsMake.com to give ideas and discuss ideas above.

1. The eternal question: is it possible to run 64-bit applications on 32-bit operating systems?

Most of the answers given are NO. But you can refer and use QEMU simulator tool. But, TipsMake.com will clarify to you the restrictions on running 64 bit applications on 32 bit OS. That is:

1. Not fully supported features, during operation will occur errors.
2. Using the emulator is a good idea, but you will not achieve the inherent speed of a 64-bit OS 64-bit OS, respectively.

1. The basic difference between Windows 32bit and 64bit operating systems.
2. Should I choose Windows 32 or 64 bit here?

Therefore, technically for this question, the answer given would be YES. You can run 64-bit applications on 32-bit operating systems.

2. Is there any way to upgrade OS from 32 bit to 64 bit, but for free?

If your computer and laptop have a 64-bit platform hardware system, the answer given here is CANNOT BE UPGRADE. You have to replace the old OS with another OS, support 64 bit.

How to check if your computer can install Windows 64 bit?

Usually, we just think that:

1. Just 4GB or more of RAM is 64 bit installed, worry!

But technically, that is not entirely accurate, but depends on the CPU - whether it supports virtualization and 64 bit. So how to test that? In Windows 10 , open the Settings section from the Start Menu , select About , and look at the right corner of the System type :

If you see the " 32-bit operating system, x64-based processor " line, you are installing a 32-bit operating system on the chip - a 64-bit CPU. If there is an x86-based processor, then your CPU only supports platform OS x86 - 32 bit.

For some CPUs that support the "first" 64 bit version, there is almost no need to require the above feature to be able to install Windows 64 bit, although technically there is support. In particular, with Windows 10 requires PAE, SSE2, and NX (you can refer to this feature at the Microsoft report here). Furthermore, Windows 10 64 bit will display a denial message if during the initial "survey" process, the installer detects that your CPU does not support.

For older computers (low-end mainboard or CPU), you must enable NX or XD in BIOS. (See more articles on how to access BIOS on different computers). In other cases, if you are performing an installation that receives an error message, restart the computer, enter the BIOS and navigate to "No eXecute bit (NX) ',' eXecute Disabled (XD) ',' No Execute Memory Protect ',' Execute Disabled Memory Protection ',' EDB (Execute Disabled Bit) ',' EVP (Enhanced Virus Protection) '. or something like that, most of those options are in the' Security 'section or ' Advanced ' and switch from Disable to Enable . Wish you success!
