Most of the time you will be having the 64-bit version of Windows 8.1 or Windows 10 (sometimes Windows 7 as well) if you have purchased the computer recently. If you have a program/app that is 32-bit, how to install 32-bit programs on 64-bit Windows? Follow this simple guide.
The truth is, the latest Windows 64-bit versions support 32-bit of application nicely without any issues. You can install and use them. But remember, you can’t install the 64-bit Programs on 32-bit Operating System like Windows 7 32-bit.
Run 32-bit Programs on 64-bit Windows
When you install the 32-bit application on 64-bit based OS, it creates a separate folder in root drive, called ‘Program Files (x86)’ and copy the all files required to run the program. So next time when you open the 32-bit program it accesses the executable program file from Program Files (x86) folder and runs without any issue with 64-bit Windows 7.
Also, 32-bit programs system files are installed into C:\ \WINDOWS\ \SysWOW64,
and registry keys are placed under HKEY_LOCAL_MACHINE\ \Software\ \WOW6432Node of 32-bit programs.
How to Identify the Version of the Program (64 or 32-bit) in Windows
You can identify the type of the programs by the location of the executable folder. If it placed under the 32-bit version of Program folder, then it is a 32-bit version of the program, another one is the 64-bit version on a 64-bit Windows OS.
Also, the task manager is another great place where you can find the version of the running programs. Open the task manager and click on the Processes where you are can see the all processes related to currently running programs. On 64-bit OS (in my case it is Windows 10), the 32-bit programs shown below. Other ones (which doesn’t have 32 Bit) are 64-bit applications on the computer.
In some cases, you may need to run the 32-bit version of applications/tools without installing them. Usually double-clicking the EXE file will open the application without any issues. If you face any issues, you can move these EXE files to Program folder inside Program Files (x86) folder in your root drive, then create a shortcut to the desktop to execute the program whenever wanted.
Hope this guide is useful to some extent to install and use 32-bit Programs on 64-bit Windows 7/8 and 10.
