I can't get it to work

I cannot find a location on my computer where the plugin file will load properly. I constantly get an error message from the plugin manager. I have a windows 10 OS updated automatically plus lightroom 4. I basically have two discs on my machine. A C: drive and an external 5 terabyte drive where all of my photos are stored and my Lightroom files are. I have tried different places close to the root of the C drive for the source for the plug in and even in the Adobe file but no luck I got the same error message. I downloaded it and unpacked it twice without luck. I even tried to put it on my external drive. The error message is always the same that it is non functioning. The plugin manager rejects it instatly]

It will NOT run on Lightroom 4. You need Lightroom 6 or Lightroom Classic.
