Ultimately, it's Java 7 that flat-out doesn't work on my PC, for whatever reason, and it hasn't with any of the files I've downloaded since starting this. (Also, I did virus scan; nothing.) When I double-click the file itself, I get a "stopped working" error, and when I direct to it with the settings file, Enigma doesn't start.
When using Java 8, it works...sometimes. Sometimes it crashes, though, and it doesn't run GM8 files correctly. Whether it's supposed to run GM8 files when Jave is set up correctly, I'm not sure, as I haven't really read much documentation on how to port from GM to to Enigma.
It is my hope that as Enigma develops, more effort is put into helping it work with versions of Java that aren't outdated, since 7, which is supposed to be the opportune one, doesn't work for me.
Edit: Worth noting: Java 7 on my PZC has always been marked as rewarding admin permission, in a way 8 isn't. I'm not sure why this is, but right-clicking Java 7 to run in Admin mode starts an installer, which then crashes with an error saying to contact the vendor. Java 7 truly is the weakest link.
