--- Comment #26 from Zebediah Figura z.figura12@gmail.com --- Okay, I may have gotten a little confused since the two people replying to this bug report have two... somewhat different problems.
I failed to notice that native speechsdk only exists in 32-bit form, and this application is 64-bit. "freehand", you seem to have tried to manually install it in a 64-bit prefix. Obviously it'll fail to load in that case.
Before trying to do anything else, can we please both try the latest *upstream* (non-staging) wine?
