Running scripts with WPI not working

[quiksilver947]

I am using WPI to run two scripts before I begin installing software. The two .cmd files I am running perform these two actions. Format a partition (D:) to use NTFS file system and create folders within this partition once formatting is done. WPI launches this command fine and it works successfully for what I want it to do. The other command is a registry tweak that does not seem to work, however if I type what I have inside my .reg file into a command prompt it works fine. I created a simple .cmd to launch a .reg file silently so accomplish this. Attached is the .cmd file and .reg file. Thanks for the help if anyone has ideas.
