Offtopic: You can write the following as

case ARGV[0]
when "register"
...
when "start"
...
else
...
end

Try this: (the only possible place where it can raise "access denied"
exception is when you rename the file (I suppose you can't do that
while it's open). If it does not help, create a log file and store the
exception stack trace to it (i.e. enclose everything in begin /
rescue.

Of course, I assume the program works when run standalone, from the cmd.exe.

Access permissions of NTFS might be in the game as well. You may try
playing with runas /user:SYSTEM, too.
