Error Mounting Virtual P:Drive

[torak289 10]

When I instal arma 3 tools through steam it needs a Virtual P drive to be created for a place for assets to go. but when I try to create the virtual P drive I just get an internal error occurred. and the cmd prompted window just closes. any help would be great :)
