Nvidia Ansel integration Issue :: DllNotFoundException

I’m interested in testing out Nvidia’s ANSEL plugin, as shared here on the asset store: Unity Asset Store - The Best Assets for Game Making

I am running Unity 5.5 on a modern (64 bit) Windows desktop with a GTX 1070 graphics card.

Unfortunately, adding the Ansel script to my main camera results in the following error:
“DllNotFoundException: AnselPlugin64”.

I have verified that the AnselPlugin64.dll file is present in my project’s Assets/Plugins folder, and that it is set to plugin enabled for all platforms in the inspector. Any ideas what could be going wrong here?

it may be that your project is built in 32bit mode
