Word not letting me past copied picture

Hello, 

I am using a software called marvin sketch and i use to to create chemical structures. I then copy them structures and paste them into word. I used to do this on my universities computers and it always worked just fine but when i treid it on my own computer it doesnt work. Instead it pastes long codes instead of the image i copied from the marvin sketch sofware. I was told by my professor that if u go into the "paste" option in "home" tab and press "paste special" i could select to paste pictures options and he showed me in university on the university computer. but when i tried it on my laptop at home, it doesnt me give the picture paste option in special paste. it only has 2 options for text and code and no option for pictures.

Heres a picture of the paste special. i dont know what to do with it now.
