Software Deployment

I have done this just the way I have done all the office 2007 and 2010 installs...

Create an MSP & a copy of the config.xml next to the setup.exe
Then a batch file to run this:
"%~dp0setup.exe" /adminfile "%~dp0Yourfile.msp" /config "%~dp0Lyncinstall.xml"

I dont put the MSP in the updates folder, I keep it separate and tell the setup.exe where it is.

I would make sure that you are using the options shown here: http://technet.microsoft.com/en-us/library/jj204651.aspx

Also make sure that your config.xml file is in the root of the folder structure where the setup.exe file is. 

I am trying to do the exact same thing and have taken your approach as well. I have had success running a script to a Windows 7 machine. Unfortunatly for me most of my clients are Windows 7 enterprise and have not been able to get the same script to work on them. I did what WhitzEnd stated as well as I created a folder named logfiles and droped that in the x64 folder. I used the online shell script and be sure you save it as a .bat instead of the default .sh. Let me know if this works for you and if it does please let me know if you had to modify it. Here is a copy of the script I used:

setlocal

REM *********************************************************************

REM Environment customization begins here. Modify variables below.

REM *********************************************************************

REM Get ProductName from the Office product's core Setup.xml file, and then add "office14." as a prefix.

set ProductName=Lync

REM Set DeployServer to a network-accessible location containing the Office source files.

set DeployServer=\\server\shared\MicrosoftLync\Lync2013\x64

REM Set ConfigFile to the configuration file to be used for deployment (required)

set ConfigFile=\\server\shared\MicrosoftLync\Lync2013\x64\lync.WW\config.xml

REM Set LogLocation to a central directory to collect log files.

set LogLocation=\\server\shared\Software\MicrosoftLync\Lync2013\x64\LogFiles

REM *********************************************************************

REM Deployment code begins here. Do not modify anything below this line.

REM *********************************************************************

IF NOT "%ProgramFiles(x86)%"=="" (goto ARP64) else (goto ARP86)

REM Operating system is X64. Check for 32 bit Office in emulated Wow6432 uninstall key

:ARP64

reg query HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432NODE\Microsoft\Windows\CurrentVersion\Uninstall\%ProductName%

if NOT %errorlevel%==1 (goto End)

REM Check for 32 and 64 bit versions of Office 2010 in regular uninstall key.(Office 64bit would also appear here on a

64bit OS)

:ARP86

reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\%ProductName%

if %errorlevel%==1 (goto DeployOffice) else (goto End)

REM If 1 returned, the product was not found. Run setup here.

:DeployOffice

start /wait %DeployServer%\setup.exe /config %ConfigFile%

echo %date% %time% Setup ended with error code %errorlevel%. >> %LogLocation%\%computername%.txt

REM If 0 or other was returned, the product was found or another error occurred. Do nothing.

:End

Endlocal

I'm looking to do this as well... I would like to deploy to multi-architecture.
