The USP4 loaded nicely without the files in quesion. I'm not sure what their purpose was, but they carried names that are part of .net framework, but of a very different binary. It would be nice to know what they do...and of course I will have to disable Avast to do any thing with them...It already stole one of them after I disabled it long enough to re extract them...just because I right clicked to check the hashes. I really do appreciate the work that Harkaz put into this rollup. It was nice to only need some POS updates when the install completed.
