This may be another Java compatibility issue. The usual solution is to rename the java folder in the Arduino directory, and see if the problem goes away.
Renaming or removing the Java folder had no effect. I have updated to the latest Java release available. Do you know where the Java directory pointer is located?
Sorry, I'm not that familiar with any programming language vocabulary. I was curious to whether or not the JRE directory could be changed for the IDE so that I could test out a previous version of JAVA besides rolling back the version already installed. Such as using the JAVA directory within the Arduino folder instead of the OS install directory. Or does it even work that way?
