Administrative Install Problems with Solidworks Explorer

I have just rolled out Solidworks 2007 (cant use 2008 yet dueto customer requirements) to our users and noticed that they donthave Solidworks Explorer Installed.
I used the following script to install:
-------------------------------------------------
msiexec /i "\\HOSTNAME\software\$\SW2007SP5\English_i386_SolidWorks.msi" INSTALLDIR="C:\ProgramFiles\SolidWorks" SOLIDWORKSSERIALNUMBER="0000 0000 0000 0000"ENABLEPERFORMANCE=0 INSTALLWDS=0 SERVERLIST=00000@flexsrvADDLOCAL=SolidWorks,PhotoWorksRender,SampleFiles,Manuals,RealViewGraphicsdisplay,ScanTo3D,SolidWorksTaskScheduler,SolidWorksToolbox,SolidWorksUtilities,SolidWorksExplorer/qb
shutdown.exe -r
--------------------------------------------------

Is there an way to Install Solidworks Installer onto the existingImages using the msiexec script??
If id added the OFFICEOPTION=1 would that have installed SolidworksExplorer??

many ThanksSolidworksAdministration
