I also agree that a bit more background on the problem and your desired result will really help.
Is there a package that also must be installed where the .reg files can piggy back the package?.... exactly what Slapp recommended (I really like this idea btw...somehow i never thought of this :-/ ) If there is no package to install, what are thoughts on creating a bat file with
reg delete and/or reg add and just push the batch?
