35.6 Locking is not possible in the directory...

Problem: I'm unable to start DVT from a shared location, at launch time I'm receiving an error "Locking is not possible in the directory..."

Solution: If you are using DVT in a shared installation setup, make sure that the installation directory is read-only for users.
