Vbscript running with admin rights

L.S.
Explanation: I want to install appv client with msiexec silently in vbscript with following command:
 

strCmd = "MSIEXEC.exe /i ""\\MYSERVER\c$\Preqs\setup.msi"" SWICACHESIZE=""10240"" SWIPUBSVRDISPLAY=""MYSERVER"" SWIPUBSVRTYPE=""RTSP"" SWIPUBSVRHOST=""MYSERVER"" SWIPUBSVRPORT=""554"" SWIPUBSVRPATH=""/AppVirt/appsntype.xml"" SWIPUBSVRREFRESH=""on"" SWIGLOBALDATA=""C:\AppVirt\Global"" SWIUSERDATA=""^%HomeDrive^%\Windows\Application Virtualization Client"" SWIFSDRIVE=""Q"" /q" 
objShell.Run strCmd,0,True 

 
- This command works when i don't add the /q at the end
- in the cmd box start as administrator the same msiexec command is working with the /q
I think that vbsedit is not starting internally the cmd box with admin rights from within wscript ?
 
What can I do to get it working ?
