how to msi install Python to non-default target dir?

I am trying to create a .bat file where (among other things) Python will have to be silently installed.
It needs to be installed to the non-default location "c:\program files\python27". Any idea how this can be done? 
I keep getting the 'Help' menu, indicating that something went wrong. I've been fighting with this for like an hour now! :-(

I followed this structure [1]: msiexec /i (yourFile).msi TARGETDIR=C:\YourBin\YourApp

The following does NOT work (I added the cd/md commands later, idem for the /qb)

y:\>set PYTHONDIR="c:\program files\python27"
y:\>cd /d "c:\program files"
y:\>md python27
y:\>cd /d %temp%
y:\>msiexec /i python-2.7.3 TARGETDIR="%PYTHONDIR%" /qb

Thank you!

All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a 

fresh water system, and public health, what have the Romans ever done for us?
