How to Publish my Application as .exe for 32bit

[Volkof]

Good day everyone,

I was watching this Youtube tutorial on how to Publish your Project as .exe
https://www.youtube.com/watch?v=iAv-vfTEyiM

I was able to publish my project successfully and run it on 64bit computer.

But when running on 32bit computer, the exe gave the error:

.exe is Not a Valid Win32 Application

My assumption is that my published program is in 64bit, hence not supported in 32bit.
Either that or I might missed out something else.

In the pre-requisites, the video ask to uncheck the "Create setup program..."

How should I publish it to work for 64bit and 32bit?
