CR Error with Update Visual Studio and .Net Framework


We have an apprication that we created in Visual Studio 2008 and .NetFramework 3.5 using CR. However, recently we update the app to Visutal Studio 2017 and .NetFramework 4.7.1, then CR isnt work (CS0246 C# The type or namespace name 'CrystalDecisions' could not be found #are you missing a using directive or an assembly reference?#).
We have installed CR Developer for Visual Studio SP25 alleady.
How can we use CR at the app?
