Replace with vl-cmdf function.
Thanks. I've seen a few other solutions also, but trying to understand what actually causes it to break. The routines were fine last week running on 2018. This week, they aren't. As far as I'm aware there hasn't been updates.
Guess a clearer question would be should they have kept working as they have and that somehow we were lucky until now...
I'm thinking it might be a windows thing tied to it (registry or something) but really don't know anything about it specifically
