Collaborate meeting.jnlp files can become associated with and try to open in another application (usually Explorer), causing it to open incorrectly with "garbage" on the page, or not all. If you are experiencing problems opening Collaborate, please follow these instructions:

  1. See if you have Java correctly installed -
    1. Find your C:\ drive. It may be called “Windows (C:)” or “OS (C:)” or “Local Disk (C:)” or simply C: and it may be found in “Computer” or in “This PC”
    2. In the C: drive, find the folder called “Program Files (x86)
    3. Find the folder called Java (there is a chance the Java folder is in the folder called "Programs") and there should be a folder in there called “jre 1.8.0_xxx” (- Depending on the current release, your numbers may be different)
    4. In that folder find “bin” then look for a file called “javaws” or “javaws.exe
    5. If you don’t have the Java folder, or the subfolders are wrong, you will need to install or repair java by going to Java.com. 
    6. If you found javaws, please continue with step 2.
  2. From within any Sakai site, click on “Join” on any active Collaborate session ONLY to download another meeting.jnlp or meeting.collab file into downloads. You shouldn’t actually start the session.
  3. Find your Downloads folder and right-click on the newest Meeting or meeting.jnlp file
  4. Choose “Open With”
  5. Look for “Java(TM) Web Start Launcher” and click on it. Collaborate will proceed to open and will use Java WS to open from now on. 

If Java (TM) Web Start Launcher is not one of the recommended programs to "Open with," continue with the steps below:      

  1. In the Open with menu or window:
    1. Windows 7 –
      1. At the bottom of the “Open With” window, click on Browse
      2. Navigate to your java folder using the method described in step 1. Choose “javaws” and Open.
    2. Windows 10
      1. At the bottom of the “Open with” menu, click on “Choose another app”
      2. Then “More Apps” at the bottom
      3. Then “Look for another app on this PC” at the bottom of that list
      4. Navigate to your java folder using the method described in step 1. Choose “javaws” and open.

Collaborate is now associated with the program that it needs to use to open, Java Web Start Launcher.
