I am pretty sure that DSC requires WFM.  If  I am right then WFM is in use and cannot be replaced unless you specify another logfile location.  Look at the DSC and see how to specify a new log location that can be used for the install. 
If the MSU is built correctly then you will require a reboot to update the install.
Try just doing WFM alone until you work it out.
I also recommend posting in the Management forum for any other issues that might be known.

DSC is a work in progress so many things have to be worked out as you need them.  Be sure to get the latest kits.  I think we are at Wave 9 now.
