Unable to run "Undistort Photos" command

[illcucuy]

I'm running version 1.2.3 and when I attempt to undistort photos, I get a "bad cast" error.  I've confirmed that the command works with some DSLR imagery within the same project.  The only difference I can see is that the imagery I want to undistort is greyscale and without EXIF info.  Is EXIF info needed to undistort imagery?  I'm looking to run a comparative densification with SURE and this is what is keeping me from doing so.  Thanks!

Hello illcucuy,

It seems that in actual release there is an issue with 16/32-bit image undistort operation (8-bit images can be successfully undistorted though).
We will fix it in the next version update, sorry for the inconvenience.
