The PHP User probably does not have write access to the new .out file
it just created.
Why Windows would be this weird, and let you create a file you cannot
write to is beyond my comprehension, but there it is...
If it's a multi-user Windows box, try logging in as the user PHP runs
as, which is IUSER_machinename, I think, on some Windows boxes...
exec() also takes 2 more arguments, which pass back output and error
code.
If Windows is giving any kind of error message and or OS error code,
you can get them by using those 2 args.
Do this first, actually, as it is better than just guessing what went
wrong.
