Did you try to update your depenencies? Maybe there´s something missing as long the bot is not able to load one of the dll´s. https://www.thebuddyforum.com/releases/68254-install-buddy-product-try-buddy-dependency-wizard.html
As Nexartus mentioned, please run the Buddy Dependency Wizard to get all the pre-requisites you need. After you run it, please reboot your PC, and try again.
