Several older Microsoft installers, particularly those changing CDs
during installation, break because they launch a child setup.exe, from
a parent process also called setup.exe, which Wine finds in the wrong
directory, as CreateProcess() first searches the parent executable's
own directory, thus re-launching the parent itself instead of the
child.  Therefore CreateProcess() must be passed a full path from
SHELL_execute(), so it launches the correct child.
