Adaptive Wide Angle Filter Isn't Straightening Lines

I'm photographing room interiors and creating panoramic shots by taking multiple shots from one vantage point then auto aligning the shots. This obviously creates severe fisheye which I've corrected with some success with the adaptive wide angle filter. However, the filter sometimes doesn't straighten out angles even when I draw a constraint. The contstraint bows along the curve and barely does anything. Any idea how to get the contraints to fix extreme fisheye?

Why not use Photo Merge?

It's years since I used AWA, but my memory is that it does not work with every image. If there are multiple complex issues, for instance, it might only be able to correct one of them.

joeyo, I tried Filter>Lens Correction>Geomentric Distortion>Remove Distortion slider on your posted image, but did not get good results. Perhaps with the original image. Give this tool a try.

I could also recommend trying the Liquify tool to do local adjustments. I'll post my version if it does a good job.

Sometimes borrowing, buy or renting a less-distorting lens is easier than "fixing in post."

This is my attempt to remove distortion using Liquify's Push Left tool, but the chairs (tables?) look bowed. If it's just optics causing the bow, try moving the central portion to a new layer an Transform the chairs. Crude method.
