Authorizing Vyew’s Use of Java

Vyew’s Screen Share and Screen Capture tools require Oracle’s Java be installed on your computer1. It is highly recommended you upgrade to the latest version of Java, Version 7 Update 51, which came out on 14 January 2014.

This update applies to Windows XP, Windows Vista, Windows 7, Windows 8, Mac OS X 10.7.3 “Lion” or newer2, and most flavors of Debian (Ubuntu) and Red Hat (Fedora) Linux, for the most current browser versions in each OS of Firefox, Chrome3, Internet Explorer, and Safari4.

This new update contains many security-related improvements, and you must “white-list” Vyew to allow your browser to run Vyew’s Java-based tools:

  1. Find out which version of Java you have installed here.
  2. If necessary, download and install the latest version of Java from Oracle’s Java Website.
  3. Bring up the Java Control Panel.
    • In Windows, check in the Windows Control Panel.
    • In Mac, check in System Preferences.
    • In Linux, at the command line, type “jcontrol” (without the quotes).
  4. In the Java Control Panel, go to the Security tab.
  5. Click on Edit Site List…
  6. Click on Add
  7. In the Location field, type “http://vyew.com” (without the quotes).
  8. Click OK.
  9. Click Continue.
  10. Click OK.
  11. You may go back to the Java test page to verify installation.

When starting Vyew’s Screen Share and Screen Capture tools, you then will need to click “Run” or “Authorize” (depending on which browser you use) when the Java Security Pop-up appears.


1. If you are only going to view someone else’s Screen Share, Java is not required. Back.

2. Older versions of Mac OS X still get their Java updates through the Apple Software Updater. Back.

3. Google Chrome does not support Java 7 on Macs. If you need to Screen Share or Screen Capture in Vyew on a Mac, use Firefox or Safari. Back.

4. Vyew in Safari is supported on Mac OS X only. Apple stopped supporting Safari on Windows back in 2012. Back.
