we added to the source files:

osquery\logger.h  -> osquery\logger\logger.h

osquery\system.h  -> osquery\core\system.h

osquery\tables.h  -> osquery\core\tables.h

and it works! now, we execute in SYSTEM terminal

osqueryi.exe --extension path\to\extension.ext.exe --allow_unsafe=true

and we came across this error:

client connected.

TPipe::GetOverlappedResult errored GLE=errno = 109

client connected.

TConnectedClient died: Tpipe GetOverlappedResult falied
