Re: Mark IV Virtual PRC-100 - quit working with latest Java update.

2015-03-03 by john.raytis@...

I believe I'm having the same issue -- Over the weekend, I lost the ability to open/run the virtual PRC after installing Yosemite/Java 8 on a macbook that had been running Mountain Lion/Java 7. I tried to downgrade to Java 7 within Yosemite (uninstall Java 8 and download/install Java7), but this did not fix the virtual PRC problem.

I restored my computer to Mountain Lion with Java 7 (from a time machine backup) and the Virtual PRC opened and worked fine.

Interestingly, I also have a PC running Windows 7. I rarely run the virtual PRC from this computer, but when I tested it this weekend, I got an error message when I tried to open the virtual PRC. This computer has Java 8. Again, I tried to downgrade to Java 7 and use the PRC, but this did not work.

I'm trying to hold onto the ability to use the virtual PRC in the event that the actual, antiquated PRC breaks. I really hope that Yamaha is able to address this issue.
