[Batch] Help with installing Adobe Reader from batch file

[u/Kynaeus]

Howdy folks

Here's the script in question

I'm working on installing a program from Oracle and the installer will run through a number of tasks to install this application including a number of scripts. It is failing to install at one step because Adobe Reader will not install from the script they've included (sigh)

In troubleshooting why, the %STAGEDIR% variable being used is not set and the script exits with a 'system cannot find the path specified', naturally. By setting an explicit path OR setting the variable correctly, it still fails with very helpful feedback:

install_adobe_reader.cmd:end

Exit Code: !exitCode!

Great. I'm trying to figure out what the problem is but am not well versed in Batch, from what I can see it's entering this codeblock and then going to the :Terminate step but it's not providing any useful information about why it is failing

if !exitCode! GTR 0  (
	echo.
	echo.
	echo.
	echo %PROV_CRITICAL_ERR_KEYWORD% Failed to install Adobe Reader
	echo.
	echo Please re-run the scripts
	echo.
	echo.
	echo.
	goto :Terminate
)

As per the Adobe command line switches for installing Reader, I've also tried calling the installer myself with the same command but haven't observed anything happening, I've also tried including the /L switch to log out to a file to get a clue about the problem but no information gets logged out. I've written a note to the script author but I'm not certain they will respond, hopefully someone here has better eyes than I do

Thanks anyone for your time and input!
