Hello friends thank you for giving me your precious time actually recently I got my computer formated and after formatting computer my ide is not working properly it is not able to even verify few example programs earlier it was working properly

this is error code of program which is coming when uploading blink program
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.
avrdude: ser_open(): can't open device "\\.\COM1": The system cannot find the file specified.


Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

Seems like the port you've selected "COM1" doesn't exist. Is there any port listed under Tools->Serial Port in the IDE? If there is one, then try using that.

If that doesn't work then, can you view if the arduino board has enumerated as a COM port? You can do this by visiting device manager (Windows) and looking under the "Ports (COM & LPT)" section.

You haven't mentioned which board you are using, but most of the earlier Arduino's used a FTDI chip to handle USB communication and if that's the case you should try installing the latest FTDI drivers.

Here's a link

I believe the problem is with your computer, not the Arduino board.
What version of Windows are you using?
I am using 1.6.3 on Windows7. The "Port" is not greyed out when I open the ide without a board connected. There are two options listed in the drop down list when I select "Port".

Disconnect the board and open up "Device Manager" on your computer.
Scroll down to "Ports (COM & LPT)" and click on the arrow.
What ports are listed?
Do any of the listed ports have a yellow ! icon?

Below is a screen print of ide without a board connected and Device Manager showing ports on my computer. Note the yellow ! icon in Network adapters.

i am using 1.6.4 and 1.6.3 and that in windows 8 .actually earlier before I had formatted the windows (windows 8)my ide worked properly
but now in same kind of windows it is not work I am thinking if there is any requirement java app or any other program for running the ide properly or there is a problem in windows.
