How to install MSP on selected computers via GPO Startup VBscript

Question

Hi folks,
I'm trying to write a vbscript that will run on startup and do the following:
1) Detect whether or not a particular application is installed
2) Determine if the latest version of said application is installed
3) If not, run the MSP update from a server and apply the patch before login.
I'm on a domain, and the script works when manually run from a command prompt.  I also have the script added to a test GPO under Computer Config>Windows Settings>Startup, but since this is my first real attempt at scripting, I'm not sure how to
determine why the *.MSP file isn't running and get this working.
Here's my code so far:
Const HKLM = &H80000002 'HKEY_LOCAL_MACHINE
strComputer = "."
strKey = "SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\"
strEntry1a = "DisplayName"
strEntry1b = "QuietDisplayName"
strEntry1c = "DisplayVersion"
strEntry1d = "UninstallString"
' Set args = Wscript.Arguments ' Get Command Line Argument
' strVersion = WScript.Arguments.Item(0)
Set objReg = GetObject("winmgmts://" & strComputer & "/root/default:StdRegProv")
objReg.EnumKey HKLM, strKey, arrSubkeys
intVersionNum="1.0"
For Each strSubkey In arrSubkeys
intRet1 = objReg.GetStringValue(HKLM, strKey & strSubkey, strEntry1a, strValue1)
if intRet1 <> "" Then
objReg.GetExpandedStringValue HKLM, strKey & strSubkey, strEntry1a, strValue1
intCompare=StrComp("Adobe Acrobat XI Pro",strValue1,vbTextCompare)
IF intCompare = 0 THEN
objReg.GetExpandedStringValue HKLM, strKey & strSubkey, strEntry1c, intVersionNum
END IF
End If
Next
IF intVersionNum="1.0" THEN
WScript.Quit 2 ' Not Found
END IF
intVersionCompare=StrComp("11.0.06",intVersionNum,vbTextCompare)
IF intVersionCompare = 0 THEN ' Everything OK
WScript.Quit 0
ELSE ' Run Update
Set oShell = WScript.CreateObject("WSCript.shell")
oShell.run "msiexec.exe /update \\RedactedServer\gpo\Acrobat\AcrobatXIPro\AcrobatUpd11006.msp /quiet"
WScript.Quit 1
END IF
Note: RedactedServer isn't a variable; I removed our servername.  Also, I'm reasonably certain there isn't a permissions issue because we use the \\RedactedServer\GPO\ to successfully deliver all of our MSI GPO updates.
When I restart, it looks like the script starts to run(?), but the update isn't installed.  In the Application log, all I see is this:
But, there's no follow-up entry indicating that it was successful or even completed.
Ideally, I'd also like to be able to pass in a command line parameter from the GPO so I can update it without having to edit the script every time a new update comes out, but I'd prefer to run before I fly.
Lastly, yes, the script is looking for Adobe Acrobat XI Pro.  I'm aware I can slipstream the MSP into an AIP and push it that way, but I don't want to redeploy a 2.3 GB installation to each computer that needs an update every 3 months when this will
accomplish the goal much quicker and more efficiently.
Does anyone have ideas?  I've beat my head against this all day, and my search-fu doesn't seem to be helping me find the answers I need.
Thanks,
Rick

Microsoft note that Office 2013 cannot be installed by Software Distribution.  The MSP you have is a patch file.  The script is a cleaner.
I do not know what is waiting for what or what script you may be referring to.
If you think it is fixed then good but I do not really understand what you are saying has worked.
¯\_(ツ)_/¯
