Setting Windows File Associations to Open .JNLP Files Properly

Close any Collaborate session or recording windows.
Open the Windows Control Panel and go into Programs and Features.
Check the list of programs to ensure that Java is already installed on the system. If it isn't installed, please download and install Java from www.java.com before
proceeding.
Download a new Collaborate meeting or recording file but don't launch the file yet.
Locate the meeting or recording .jnlp file in your Downloads folder.
Right-click on the file and choose Open with then click Choose another app.
If you see Java (TM) Web Start Launcher in this list (you may need to click More apps to expand the list), select it and check the box that says Always use this app
to open .jnlp files then click the OK button.
If Java (TM) Web Start Launcher is not in the list, check the box that says Always use this app to open .collab files then click Look for another app on this PC.
Navigate to the following location:
c:\program files\java\jreXXX\bin
XXX represents a number that will vary based on the version of Java installed on the computer, for example: 1.8.0_251.
Select the file named javaws.exe and click Open.
Going forward, all .jnlp files will open using Java Web Start.
