I am trying to update Java 8 to the latest version on my Window 7 Pro PC. However, I persistently get this "fatal error" at the end of the install:
Error Code 1603: Java Update did not complete.
I've tried using numerous methods - the built-in Java updater, Ninite and PatchMyPC, and all give the same results. I also tried temporarily disabling running apps in the background (such as Kaspersky AV) but it made no difference. I don't recall having trouble installing Java in the past, so not sure why it has become a problem now.
So this leads onto a few questions:
1) How can I update Java 8 to the latest version without getting an error?
2) Do I really need Java installed anyway? My only reason for installing it is that I frequently use OpenOffice and LibreOffice. However, I only really use the basic spreadsheet and word processing functionality (not databases etc.). Also, I can't see a valid reason why a modern web site would need to use Java.
3) Do I need to install a 32-bit or 64-bit version of Java, or both? I am using a 64-bit PC with 64-bit Windows. I had both 32-bit and 64-bit versions installed but it appears they were both uninstalled with PatchMyPC when attempting to update (it runs the Java uninstaller before attempting installation of the new version).
