AppLocker: Deny one app for all except Publisher/another App

Hi,

Windows 10 1809 Enterprise (corporate install)

I need 2 versions of Java RE installed: an older version for a bespoke app and the latest version. The old version must only be able to be used when called by the bespoke app and nothing else. And the new version must be used for all other apps but never by the bespoke app.

Is this possible with AppLocker?

Thanks

I've had a rethink.

You you create a deployment rule set for Java RE so you can force certain URLs to use a specific version of RE. However this doesn't effect WebStart apps and that's what I need.

Has anyone been able to a specific version of WebStart?

Thanks
