Disklavier

Good evening, everyone.

I am able to run the Virtual PRC in El Capitan on my Mac by downgrading Java to Java 8 Update 25. Given all of the security issues surrounding Java, especially older versions of Java, I am not advising anyone to do this downgrade. However, if you want to know how it is done, here are the instructions:

1) Verify your version of Java.
To determine your version of Java, select System Preferences from the Apple men. Then click the Java icon to bring up the Java Preference Pane.

Click the Update tab to see what version of Java you have.

2) If your version of Java is earlier than Java 8 Update 25, do not use the update feature of your Java Control Panel because it will update to a later version of Java. Instead, download and install Java SE Runtime Environment 8u25 from this location:

http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html#jre-8u25-oth-JPR

3) If your version of Java is later than Java 8 Update 25, uninstall Java and then follow the instructions in Step 2. Instructions for uninstalling Java may be found here:

https://www.java.com/en/download/help/mac_uninstall_java.xml

4) When your computer gives you messages to update Java or block Java, ignore them.

5) In your Finder, locate your Disklavier, which will show up as a computer on your network with a name that starts with dkv. Open the Disklavier, locate the DNA folder, and double-click VirtualPRC.html.

6) This will open a page in your web browser. Log in with the following username and password (unless you have changed them):

root
prcstart

7) Click the Start button. This action will download a file called prcstart.php.jnlp. Locate the file and put it somewhere for future use. Then, double-click the file. This action will launch the actual PRC Java application from the Disklavier’s hard drive.

Next time you want to run the Virtual PRC, locate and double-click prcstart.php.jnlp.

Regards,

I have tried running this and it momentarily brings up Virtual PRC in menubar and then fades away to nothing.  When I get info on the file it is set to use "java web start.app(default).  Is there a way to run this script?  I do not see prc100.jar on my hard drive.  I am clueless.  Thanks Joan
