The Wireless Manager UI freezes at 39% or complains it can't find Java

Both the Wireless Manager server and client require 32 bit Java environments to run.  This particular problem is most often seen when running on a Windows client machine, and the client machine either does not have a 32 bit Java Virtual Machine (JVM) installed, or it is not properly associated with the correct extention (.jnlp).   

  1. Download and install a 32 bit JVM from the Oracle website.  Note the location that it is installed to.
  2. In Windows, go to Start and select Default Programs.
  3. In the resulting UI select "Associated a file type or protocol with a program.
  4. In the resulting list, search for .jnlp, select that row, and then select the Change Program button.
  5. Ignore the "Recommended Programs" as it may default to a 64 bit JVM which won't work.  Instead, click the browse button and navigate to the 32 bit JVM install directory.  This is typically somethig like C:\Program Files (x86)\Java\jre7.
  6. Select bin and then javaws.exe (be careful not to select javaw.exe).
  7. Select Open, and then Ok and close as necessary to exit the dialogs.
