Hi, My PC'OS is Windows XP of Japanese version. Arduino IDE ran correctly once.Now It can not start. When I click it, an error message is shown in Message Box. It is like '0x7c951689 can not refer 0x00000000. The memory can not become "read" '. Actually, Japanese message is shown on my PC. The board is Arduino Duemilanove. What should I do?
Try using the run.bat file instead of arduino.exe.
Thank you for your response. I will try it.
