There's some threads on getting sachesi to run. You have to download a file from Microsoft. Mine was giving me a error so I just used Darby but the other day I got curious what it was and started searching. It was easy to find but I don't have a link off hand.
The problem I had was the 7Zip app from windows. OnceI downloaded from 7zip.org Sachesi download fine and was working. The windows version would not get all the files.
