Hi Dawgmatic
I understand you want to know where the 7zS2356 folder is located.
The easiest way to find it is to click on start, in the search programs and files box type in %temp% and click enter key for Win 7. Win 8 you would go to the start up screen (tiles screen) and just start typing %temp% click on %temp% on left side of window.
Once you open the temp folder locate the 7zS2356 folder and open the setup.exe from there.
Hope that helps.
