I downloaded the open installer, and tried running the .exe file in the zip folder. It gave me an error of being unable to load file "~/rt/jetrt/XKRN48089.dll."
Short of making folders and subfolders for everything (which I might not even do correctly), I don't know what to do.

As a note, I am an idiot for these things. How do I get it to work properly?

Use the link in my signature and try the Java version.  (The directions in my siggy are for the java version.)

extract everything before you try to run it.

The .exe file is the only thing in the archive, right?

Nope. It could be, but that'd greatly increase the size of the total package, and I'm not sure it'd work correctly.
