avr-gcc.exe has encountered a problem and needs to close

Hello, I've just bought my fist UNO. The USB driver is installed and working ok.

I'm trying to upload the BLINK example.

I've opened the file and clicked COMPILE

Then I get this?

avr-gcc.exe has encountered a problem and needs to close

I'm stuck straight away, can someone advise please?

Windows XP pro 2002
Celeron 2.66Ghz
IDE 1.6.5

It seems to be a Windows problem not a avr-gcc.exe problem.
Did you already tried to use in another computer?

Yes, on my laptop the compile & upload works!

But the avr-gcc.exe seems to be installed in the arduino directory?
I have not seen this problem before I installed the arduino IDE.
Do you know what avr-gcc does?

Do you know what avr-gcc does?

AVR-GCC is a compiler that takes C language high level code and creates a binary source which can be uploaded into an AVR micro controller.

I've fixed the problem.

I ran the unzip program again and when it asked me to over-write the existing programs, I clicked 'yes'.
After that the arduino compiles and uploads on my main PC
