Installing Java on LattePanda

Hi,

I got

Lattepanda 4GB RAM/64GB eMMC Windows 10 64-bit Unactivated

and it seems like I can't install Java Runtime Environment on it.
I tried different executables from oracle.com website, but it always falls through:
- window does not pop up, it seems like nothing has happened
- it says Windows can't run that app saying it's 16-bit

I've tried different installers, including:

jdk-12.0.2_windows-x64_bin.exe

jre-8u51-windows-x64.exe

jre-8u221-windows-i586.exe

jre-8u221-windows-x64.exe

How do you guys set up Java on this machine?
Is something wrong with the LattePanda native Windows?

Cheers
