In general, I try to keep the virtual PRC running on my computer, even though I never use it.  Each operating system upgrade (I'm on Windows), and other large change (newer Java version) causes some hiccup or another.  My primary reason for keeping it running is that DKVBrowser doesn't cover all of the features (the primary one that is missing is the ability to start a backup).  My real PRC-100 is in need of a battery replacement, and if I were to find that it was actually, dead, and I wanted to start a backup, I'd need the virtual one...so, I work hard to keep it running.
Anyway, I'm currently able to run it on Windows 10, and the latest java, but I had to bypass a few of the steps that are part of the normal launch procedure.
Nowadays, I have an icon (shortcut) on my desktop which a target of:
"C:\Program Files (x86)\Java\jre7\bin\javaw.exe" -cp prc100.jar gui.prc100 -h=192.168.0.6 -p=3191 webremote -w=31910

and a start in (default directory) of C:\users\kevin\
and in C:\users\kevin is the actual "prc100.jar" (this is the actual prc100 program) that I had to manually download from the piano (I can probably explain how that was done, or just share this jar file since you all already have it anyway).
So, basically, this shortcut runs javaw.exe, and passes it a bunch of important command line parameters.  As it turns out, you would all need the same command line parameters (I believe), aside from the one that looks like this:-h=192.168.0.6as that is the IP address of my piano on my network.  You would need to replace it with the (hopefully fixed) IP address of your piano.
By doing it this way, I'm bypassing all of the nonsense that Yamaha built in (which mostly doesn't work anymore), involving dynamically figuring out this command line, and delivering the jar file to your browser behind the scenes (I think this was called jnlp, but I could be mis-remembering).
I'm not entirely sure how one would do this on the mac, but I bet the above command line would work just fine from a shell prompt there.

 Subject: [disklavier] Mark IV virtual PRC with Windows 10 or El Capitan
   
    Has anyone tried running the mark IV virtual PRC using Windows 10 or El Capitan?  I've lost the functionality of the virtual PRC when upgrading to new operating systems in the past, and I'm wondering Window 10 and/or El Capitan are still able to access the disklavier and run the virtual PRC.  #yiv1001809995 #yiv1001809995 -- #yiv1001809995ygrp-mkp {border:1px solid #d8d8d8;font-family:Arial;margin:10px 0;padding:0 10px;}#yiv1001809995 #yiv1001809995ygrp-mkp hr {border:1px
