Deploy an msi with an msp in same command line

Hi,

I have seen question about this many times but I still have som issue with installing msp with msi.

I use this command but for PATCH is the fullpath is crucial, but the msp is copied to the client cache so i dont know the full path to the msp.

"msiexec /I <misfile.msi> /qb PATCH=<fullpath\topatch.msp> TRANSFORMS=transform.mst"

Sometime i put it in an cmd file and that works fine in Windows 7 but I have issue in Windows 8, for

install.cmd

"msiexec /i %~dp0misfile.msi PATCH=%~dp0topatch.msp TRANSFORMS=%~dp0transform.mst"

so how to handle PATCH fullpath is you use SCCM Applications and Package?
