10.3 and 3.1 Java Version 8 Not Allowing WebClient Install
Problem
The security in Java version 8 is not allowing WebClient installs.
When trying to run the WebClient install, the browser returns an error that states 'Failed to validate certificate. The Application will not be executed.' After clicking through the error, the page displays another error 'Setup cannot run from this Web page.'
Solution
In the past, lowering the Java security settings to Medium was an option, but in Java version 8 that is no longer possible.
Try these steps:
1 Add the install URL as an Exception in the Java console and as a Trusted Site in your browser.
2 Try installing in IE11, Chrome, and Firefox.
3 Try installing by running the WebClient setup locally.
If you still get the errors, use the method outlined in VSI KBase #2642
OR
Install with an older version of IE (version 10 or below).
