The Tone Mapping Plugin works in Photoshop CC, Photoshop CS and Photoshop Elements.
If you wish to use the Tone Mapping with a 32-bit merged HDR image, then you'll need Photoshop CC or Photoshop CS2 to CS 6.
Customers reported that the Windows version of the plugin works in Affinity Photo as well. If you are using the Tone Mapping plugin with another host than Photoshop, we would very much appreciate if you could contact us to let us know.

Note that you won't get the issue if you apply the Tone Mapping plugin to an existing 32-bit merged HDR image file you've opened. You won't get the issue either if you copy and paste the newly 32-bit merged HDR image into a new file, and then apply the plugin.

This was an issue in the older version of the Tone Mapping plugin, which was fixed in version 3.0.
