problem connect using di api

Recently, i updated sap 8.8 to 8.8.2 and i try to rebuild my app.

when i try to connect using di api, i have two errors

First, visual studio displayed this message

error al iniciar la aplicación porque no se encontró Xalan-C_1_7_0.dll. La reinstalación de la aplicación puede solucionar el problema

And sap returns this

Error: 126

Message: OBserverGeneric::GetNewLibraryFromServer: LoadLibrary for observer failed System error 126

i think the problem is the dll but i unregister and register SAPbobsCOM88.dll

thx
