Most likely, the user your webserver runs programs as does not have the right permissions. Have you looked in your webserver error logs or the Event Log? Does your program work from the command line? Does test.exe output to STDOUT or to STDERR?

system tells you when it returns 0, which has little to do with CGI, so possibly, your program can be run, but it puts its output where you can't catch it?.

The length of an array is usually determined by using scalar @array, and I think short of using a tied array, you can't get the length to be negative. Maybe you used $#array which is commonly referred to as "the index of the last element in @array", which is always one less than the length of the array?
