#include Papersprite.h not recognized on different PC's

I created a cpp file that has a paperSprite. To make the paperSprite i used the include #include “PaperSprite.h” in my cpp file and it works on my end. I pushed my code to perforce and someone else pulled it. On his end he got the issue that his VS could not find the include. Multiple people now pulled the code and for 2 people it works and 2 other people it doesn’t.

Is there something wrong with the way I include the PaperSprite ?
