I'm on win 10 and I got the same problem... it took me about 5 years to finally found the solution.... Roboguide do some grant acces using the account "Users". My windows is in "French" and in french there is no account named "Users"... just a account named "Utilisateurs".
So I just create a temporary account named "Users" (and give it admin right..just in case) and "voilà le tout fonctionne" (translate : IT WORKS!!!).
Maybe is not the same solution for everyone but it woks for me
