Problem with Honeybee

Hi all, 

I've got a problem with Honeybee. When I launch "honeybee export to openstudio" on my PC appear an error:

1. Solution exception:file does not exist: C:\Users\Utente1\AppData\Roaming\Ladybug\OpenStudio\openStudio.dll

I control in this folder and the file exsist.

So where is my error? 

Thanks
