IDE 1.6.2 won't run on my Dell XPS windows 7 64 bit machine. After searching the forum, I found the posts regarding 1.6.1 not launching.
I checked the arduino.l4j.ini and arduino_debug.l4j.ini, and both files already have -Xmx512M instead of -Xmx1024M
Following the suggestions, I ran debug, and got the following repetitive message:
at processing.app.Base.addSketchesSubmenu(Base.java:1551) at processing.app.Base.addSketches(Base.java:1471)
Under Programs I have jdk1.8.0_40 and jre1.8.0_40 Under Programs(x86) I have jdk1.7.0_51, and jre.8.0_31
Of course IDE 1.6.2 runs just fine on my Windows XP desktop and Vista Laptop.
Thanks Paul G.
