I am trying to install the MSXML Parser 6 from within an Installshield Installation. I am trying to do it this way:

function InstallXMLParser()
NUMBER nLaunchValue;
begin
nLaunchValue = LaunchAppAndWait(SUPPORTDIR ^ "MSXML6.MSI",
"", WAIT);
if (nLaunchValue < 0) then
MessageBox("Unable to install MSXML Parser!\nSee user's guide to install manually.", WARNING);
abort;
endif;
end;

For some reason I cannot install it this way. "LaunchAppAndWait" returns a value of less then 0. Any ideas.

That's because MSIs are not a supported program extension and therefore cannot be launched directly.

Instead they need to be passed as an argument to the MSIEXEC.EXE application and that's documented over here in the Basic FAQ.
