There is no separate JRE anymore, only the JDK which includes all JRE parts (e.g. the java binary). Also, do not use OracleJDK unless you intend to pay them money. OpenJDK is the new default. Answer from 0x256 on reddit.com

r/javahelp on Reddit: Can't download JRE 64 bits on Windows 11, error 1603
January 20, 2024 -

I don't know if this is the right place to ask this, but there are some posts about this same error, so here it goes.

For some reason the obvious download button for Java (JRE) downloded a 32 bits version, even while using a 64 bits web browser. After realising that the version I had of Java has not the 64 bits one, I unintalled the 32 bits version in the control panel and while trying to install the 64 bits one I got the 1603 error message.

After this I tried a lot of troubleshooting methods I saw online, but none of then worked. Just to clarify, I've being for the last 3 hours trying out everything I can find on java's site, reddit, youtube and tech support sites about troubleshooting JRE installation, but nothing I did worked.

Am I doing anything dumb? Why does the 32 bits version downloads but the 64 dosen't? Is there something obvious i didn't find?

I'm on the latest version of windows 11, using latest verson of the firefox browser, in a dell g15 laptop

thank you
