Actually a little more work has shown the following. When using CreateProcess
on windows, if lpApplicationName is used, the value passed will not be added to
the start of the lpCommandline string. 

Therefore using GetCommandLine will never retrieve this string. However it
appears that the is a quirk left in the way the CommandLineToArgv function
works. If the string (usually the return value of GetCommandLine) passed in
starts with 1 or more spaces, then the first element of argv (argv[0]) will be
an empty string, and the rest of the command line will be broken up into the
subsequent array elements.

Obviously this means that using 
argvW = CommandLineToArgvW(GetCommandLineW(), &argc);
would fix "Install RPG Maker XP", it would at the moment break the xlviewer
installer.

Right now I've eliminated CreateProcess, the creation of argv sent to child
processes (build_argv), and GetCommandLine from being points of error.

So either CommandLineToArgvW has a bug in how it generates the command line
from the xlviewer installer, or msiexec will need to include a work around for
dealing with this special case.
