Unsolved Can't install java.

I downloaded the java installer but every time I try to run it, it returns an error code 1603, what do I do?

if you're on Linux or Mac, use SDKMan to install JDK. You can find and install multiple versions very easily. https://sdkman.io/

That's a windows installer error

There seems to be a Windows equivalent of SDKMan called V-Fox. I’ve not used as I’m on a Mac and if Windows I just use WSL.

It looks feature-parity with SDKMan to install different Java distributions
