How to fix java error code 1603?

[rebeccareed]

Installing Java fails with java error code 1603 on my Windows machine. I tried uninstalling old Java versions and running the installer as admin, yet it still fails. Any tips on logs to check or system settings that commonly cause this?

Have you tried to check Windows Installer log? Sometimes error 1603 will occur if there's a permission problem on the folder where Java is being installed. You can also try installing the Java when I instead of the default Program Files, install Java in like the C:\Java directory. That was it for me the last time.

Ah, the infamous 1603 debit insofar as Windows says; "Nope, not today, buddy." Typically I would just uninstall all of the old java versions, reboot and run the installer with admin rights. If that's not working change the name of your programs files java folder and try again. Windows is weird like that.

Honestly, some people here will tell you it is a registry problem, others by swearing by having leftover java folders removal. Of the two I've done both and personally the registry fix worked for me. But make sure that you check your registry before doing this or you might regret it.

Look at any other apps that you might have running, which may be blocking the installation of Java, such as an antivirus or security software. I once spent 3 hours troubleshooting 1603, only for it to turn out that what was stopping the installer was Avast. Pausing it enabled Java to install instantly.

Bro, 1603 is basically Windows’ way of trolling you. I've sometimes just gone in the JDK that it comes with instead of JRE its bigger, but works every single time. Fight me.
