I have installed the arduino program and did everything as it was said but I keep getting something really strange when I try to upload or verify a sketch because of this error.
I have attached a screenshot.
please help me
Rein.
P.S. I use windows 7 home premium (I thought 32-bits but it can be 64 thoug) and and arduino uno.
I don't see an error message in that screen capture. You should be able to select text in your Arduino window and copy and paste it into a forum posting.
The Arduino IDE is a Java program. Perhaps you should check for a Java update.
