Windows Installation Instructions, All DLL Files Missing

[Christopher Miles]

I really appreciate all of the helpful comments in this thread! I have 
made a lot of progress on this issue, I can compile and run my 
application and am working on packaging.

In my opinion, my big problem was that when I was compiling I wasn't 
setting the correct flags with `javac` and, at the same time, probably 
didn't have the correct flags for `java` either. To be honest I was 
mostly button mashing at that point in the hopes that I'd stumble across 
the correct combination.

To get everything working I have moved to using the "mods" with `javac` 
and to compile and then using `jlink` build an image. After `jlink` runs 
I am using the `java` that is in the image directory to run the compiled 
"JAR" file and that is working well.

I think one big hurdle here was my lack of familiarity with Java modules 
and how they work. While I knew that Java modules had been a thing for a 
while I've been working on non-Java projects and it was not at the front 
of my mind.

While the examples on the JavaFX "Getting Started" page worked for me, I 
don't think I came away with a clear understanding of what the flags 
where actually doing and that made it a little harder to migrate that 
information over to my own project. My thinking is that using the "mods" 
will make it easier to eventually get my application packaged but I'm 
not entirely clear on the bit about the JavaFX runtime and if I need it 
at all. I don't think a discussion of the Java modules system would be 
appropriate on the "Getting Started" page, but maybe getting a little 
more into the details of which approach makes the most sense (mods vs. 
the SDK) in which situations would clarify some things.

Thank you all for your help on this! :-)
