Hi, Bo!
My name is Caio and I'll be happy to help you today =)
As this isn't a common DLL, the best you can do is to try to reinstall the program. But first, when uninstalling it, make sure to clear all the stored data. Once done, check if all the dependencies the app may have are installed and then install it again.
I hope this helps you! Please let me know if I can assist you more.
Best regards,
Caio G.
