installing the IDE

i am having an problem with installing the 1.6.5. r2 and all of the other IDE . i am getting frustrated

when i was unziping it, it asked me for an password . it said th source must have placed an password on the file its so frustrating because its my first time and i wanted to get a little use to the arduino IDE

Wait a minute. When you unzip the folder, it asks you for a password? Please post a screenshot. That should NOT be happening.

There are no password in our zip. What would be the purpose of it !?!? Please download the IDE from the only official location: http://arduino.cc/en/Main/Software
