Error by adding essentialmode and es_freeroam

Hello,
I’ve an error when i’m adding essentialmode and es_freeroam (and any script i’m adding which is using essentialmode).
Here is my error : http://imgur.com/a/UUlQy
I think it’s a Windows error (Win10 Pro 1607) because i’ve tried the same server folder on a virtual machine and I didn’t got these errors.

Do you have any ideas about what it could come from ?

Thank you.

(btw sorry for my bad english, I’m french)
