There is a new version of the TopCoder Java Applet, see also here for instructions. If the file extension “jnlp” is not recognized, follow the instructions here.

If you added the “bin” java folder to the system path variable, then you can open the “jnlp” via the Windows terminal as follows:

• Navigate to the jnlp file.
• Enter “javaws ContestAppletProd7.2.jnlp”
