New Java v8 JRE version not installable over old one: How else?

pstein-JavaNet Member Posts: 686 Bronze Badge

I have a 64bit Java JRE v8upd333 installed here on 64bit Win10 in the following folder.

C:\Program Files\Java\jre8\

Now I want to install the latest downloaded JRE or more exactly replace the previously installed JRE completely.

When I double click on jre-8u341-windows-x64.exe and start the installation I am asked for the target installation directory.

If I select C:\Program Files\Java\jre8\ the installation is denied and I am asked for an EMPTY directory.

What is this?

Every other stupid program manages to install a new version over an old one - only Java apparently not.

Do I really have to manually uninstall the old JRE version before I can install the new one?

As far as I can see there is NO separate Java Updater (service/program) currently installed. But this shouldn't matter.

How can I install a new over an old JRE by double clicking the new package file?
