How do i download windowblinds if i dont have the software

What you download here are SKINS for the program WindowBlinds. It´s like the colored casing to a cell phone. The casing is virtualy useless on it´s onw, but it can change the look of that phone. It also usually only works on that one phone. So it is also true with skins: rarely do they work for other apps (with a few exceptions).
