Good afternoon,

I got a problem trying to package a plugin with the header : “ShlObj_core.h” who let me read on AppData folder on Windows.

I got this problem first on a custom Blupint Plugin :

  1. UATHelper: Package Plugin Task (Windows): In file included from XXX\Test_Plugin\HostProject\Plugins\Test_Plugin\Intermediate\Build\HTML5\UE4\Development\Test_Plugin\Module.Test_Plugin.cpp:3:
  2. UATHelper: Package Plugin Task (Windows): XXX\Test_Plugin\HostProject\Plugins\Test_Plugin\Source\Test_Plugin\Private\Test_PluginBPLibrary.cpp(33,10): fatal error: ‘ShlObj_core.h’ file not found

  12. UATHelper: Package Plugin Task (Windows): BUILD FAILED

On my second try i try to create a plugin with just “ShlObj_core.h” with the import lib plugin, and i got this error:
