I followed the instructions for setting up my arduino Uno. Installed the drivers from the problem folder, selected the Uno and COM 3 port. But when I try to run the Blink test sketch, I get the following error:

avr-g++: CreateProcess: No such file or directory

Has anyone else encountered this problem? How can I get this to work? I redownloaded the files to see if that would fix it, but it has not. I'm running Windows 7 64-bit ultimate and using the 1.0 IDE.

I already saw that thread. Tried adding #include "WProgram.h" but that didn't work. Running echo % GCC_EXEC_PREFIX% in the command prompt returns % GCC_EXEC_PREFIX% and the rest of the thread is over my head.

Remove the space...

% GCC_EXEC_PREFIX%

Yep I just tried that. It now returns c:\progra~2\egcs\lib\gcc-lib\

I take it I'm supposed to remove that system variable somehow? How do I do this?

Edit: Found where to remove it. Trying again now.

Edit2: Yup, it works now. Well, that's interesting. I'm not sure how that variable had been set.

For those that find this thread later, do the following:

Open the Command Prompt
Type "echo %GCC_EXEC_PREFIX%" into it, without quotes of course.
If it returns a path of some sort, you'll need to remove it.
Press Start, and right click on computer.
Click properties, and then Advanced system settings, located on the left of the window that opens.
Click Environment Variables, and locate GCC_EXEC_PREFIX in the list near the bottom of the window. Select and delete it.
Restart. Uploading should work after restart.

It's probably a lot easier to just type:
GCC_EXEC_PREFIX=

Restart. Uploading should work after restart.

restart what?
