Can't get Newtek NDI plugin to work / I don't know what I'm doing.

Hi, having some issues getting the newtek NDI sdk for UE plugin to work. Running UE4.26 (the latest version) and the current download of the NDI UE plugin from newtek's website. OS is windows 10 20H2 19042.685, xeon e3 1231V3, 16GB ram, gtx1070.

Downloaded the latest version from newtek's website, run it, and copied the relevant folder into the engine's plugins folder. The readme document does say:


but i don't really get what it's trying to say, and searching the documentation doesn't really bring up anything that looks like it will help.

When enabling the plugin in a project and restarting the editor it brings u a popup saying something along the lines of "modules are missing or built in a previous engine version, would you like to rebuild them now?" which seems to be normal, but choosing to rebuild them then brings up the "could not be compiled try rebuilding from source" and then will only give the below message when trying to open the project:


I'm not very familiar with proper UE workflow, I'm really just looking into the virtual production and dmx control side of it (because that's my job), but I'm not seeing any solutions in my searches that have helped. I'd use the spout/dx12 output plugin but that's still only compatible with 4.25 and less useful. I've seen others use the NDI plugin with 4.26 and not suggest that there were hoops to jump through before it would work.

Can someone translate this into simple speak for me, or (ideally) suggest steps to resolve this that I might be able to follow? I fully get that this is probably me just not understanding something and not knowing how to fix it.
