The problem here is that the way most support boards work is that people (the help seekers) post problems, giving lots of details, but the people reading it (the help givers) pretty much ignore everything written and just try to drop it into one of the established slots - and then give pre-programmed help information for that "slot".
So, here, no one knows what you're really trying to do, and there isn't anywhere near enough bandwidth here to accurately ferret it out. Rather, people just assume that you are trying to run a Windows (*) program on the Pi - and giving out the standard, pre-programmed, "You can't run your WIndows apps [Word, Excel, etc] on the Pi, because the Pi is ARM, not x86 (you silly goose!)"
(*) Because for most people, the terms "computer", "PC", "x86", and "Windows" are all synonymous.
Now, kidding aside, we are beginning to get a glimpse of what you've got - some kind of encrypted shell script - presumably, one that starts out with ordinary plain text (since a shell script, by definition, has to start that way), followed by lots of binary glop - and somehow, the plain text part interprets (decrypts), and runs the binary glop part. But, note well, whatever it is you've got (and whatever evil vendor supplied it), it's way beyond anything any of us have ever dealt with - and, as I said earlier, there just isn't the bandwidth here for it to get explained to us to the point where we could comment intelligently.
Such is the support forum game...
And some folks need to stop being fanboys and see the forest behind the trees.
(One of the best lines I've seen on this board lately)
