Multi Objects Renaming Tool

I just purchased MORT and I think it’ll be perfect for what I’m looking to do. We are using a customized version of the engine on the project I needed this for. It shows up in my library as OTHER instead of 4.18 that it’s based off of. How do I add this plugin to that project?

I tried installing it to the 4.18 clean install I have and then copying the files over to our project folder. When I launched the engine it said I needed to rebuild the plugin. I did so and everything went fine (I didn’t get any errors or anything), however when I restarted the editor and enabled Blutility plugins and tried to show plugin folders the MORT folder doesn’t show up (other plugins show up when I enable that).

Thanks in advanced for any help you provide.
