How to change JRE version (from 8 to 6) in IE and Chrome?

Question

Java

Hello.
Faced with an interesting problem. I need to go to one link. When you click on this link, a jnlp file is downloaded to your computer, which is launched. I have determined that this jnlp file can only be run under java version 6u45. I have java 8 on my computer. I didn’t want to delete it and just put java 6 next to it. I reconfigured it and now when I run the
java -version command, it tells me that I’m working with java 6
Everything would be fine, but when I run it through the browser, it for some reason it still uses java 8. You can run it through the console through the javaws command, but I need to run it through the browser.
Question: how to make the browser (in my case IE and Chrome) use JRE 6 version.

Answer 1

This feature was a bug. For example, it was possible to find an old vulnerability and force the toad plugin to run the vulnerable jre version. This bug was closed a long time ago, so it will always run only on the latest version.
