In my last post I mentioned the error I had been getting trying to use WiiFlash, particularly using wiiFlashServerJ which stated “Cannot launch Java application. Uncaught exception in main method: java.lang.IllegalStateException: Bluetooth failed to initialize. There is probably a problem with your local Bluetooth stack or API.”
Luckily I found a solution to this in the WiiFlash Forums.
In the Finder, and select Get Info from the File menu.
In the info panel, click the Open in 32 Bit Mode checkbox.
Please let me know if this works for you.
