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).
- Download and install a 32 bit JVM from the Oracle website. Note the location that it is installed to.
- In Windows, go to Start and select Default Programs.
- In the resulting UI select "Associated a file type or protocol with a program.
- In the resulting list, search for .jnlp, select that row, and then select the Change Program button.
- 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.
- Select bin and then javaws.exe (be careful not to select javaw.exe).
- Select Open, and then Ok and close as necessary to exit the dialogs.
