For a number of environment specific reasons that don't merit discussion here - I am working to install the Lync 2013 client via a windows command line script in batch form.  I need to understand the exit codes (errorlevels) returned by setup.exe for Lync 2013 - and have not found them listed anywhere.  Can anyone point me to these?

I'd think the Lync forum would be a better place for this but.... It should use standard msi error codes.
