Nope, after you extract dsdplus1p101, open the folder, there a text file dsdplus that explains , you have to download and extract the .dll files and place them in your dsdplus folder
This link should download a zip file. As I mentioned to you here, you'll need to extract it then you'll find the executable programs contained within. There's no installer file so you'll need to read "DSDPlus.txt" for instructions
