Custom engine's plugin not being packaged

Thanks for getting back to me.

  1. I’m using 4.7.5
  2. yes, it’s a Blueprint project
  3. yes, all the projects using this plugin
  4. windows
  5. we tested on several windows 7 computers

I stepped back a bit and I tried to “Launch” my project instead of “Play”. It does not work either, it says that it’s missing my plugin. To make sure you fully understand what I’m doing: a colleague of mine created and compiled a plugin to add the support for a specific input device we are using. So on my machine, I have the binaries of the plugin installed in my engine’s plugin directory. When I try to launch or package the game, it says the plugin is not there. Is it an expected behaviour? (not copying the plugin dll)
