[@jULIO] Here’s a hint if you want anyone to be able to try and help you… NAME the DLL that is reported as being missing! NO ONE can help you without that information!!!!
[@TK] There is NO license to activate as SOS installers for Vovsoft products are built pre-activated and you do not need to enter a license code and I doubt the veracity of the original posters complaint if they installed using the SOS installer.
