Deploy all 19 patches for Acrobat 9 in one step?

I have about a thousand machines that are all running Acrobat 9.0.0 - I wrote a script that looks like this:

strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

On Error resume next

Set colAcrobat = objWMIService.ExecQuery ("Select * from Win32_Product Where Name like '%Adobe Acrobat%'")

For Each objSoftware in colAcrobat

          Acrobat = objSoftware.Upgrade (".\AcroProStdUpd910_T1T2_incr.msp",REBOOT=ReallySuppress)

          Wscript.Echo Acrobat

          Acrobat = objSoftware.Upgrade (".\AcrobatUpd911_all_incr.msp",REBOOT=ReallySuppress)

          Wscript.Echo Acrobat

          Acrobat = objSoftware.Upgrade (".\AcrobatUpd912_all_incr.msp",REBOOT=ReallySuppress)

          Wscript.Echo Acrobat

          Acrobat = objSoftware.Upgrade (".\AcrobatUpd913_all_incr.msp",REBOOT=ReallySuppress)

          Wscript.Echo Acrobat

etc etc

Right about after it installs 9.1.2 - I get an error with 9.1.3 - basically I need to reboot.

Is there some way of doing it in one go? This may work better if I run the script via sccm with the user logged off, but testing this thing is a total nightmare .
