Thanks so much for looking in to this.
Maybe it's not the /options which are creating the challenge, but something peculiar about the Ninite Updater application itself?
Unfortunately, Ninite Updater https://ninite.com/updater/
is not available in a free trial.
My current Ninite Updater license will expire in about a month; I could give you a copy of that for testing, or I'll happily buy you a one-seat license to Ninite Updater (USD$9.99) if you'd like.
