Crystal Report for Visual Studio 13.0.12.1494 upgrade to 13.0.22.2668

Hello Crystal Report Expert,

I am running into an issue when trying to convert an existing Visual Studio 2013 project with integrated Crystal Report for VS 13.0.12.1494 component to Visual Studio 2015 project with integrated Crystal Report for VS 13.0.22.2668.

The new Windows 10 machine has VS 2015 installed and integrated with CR for VS 13.0.22.2668 properly. I verify this by creating a simple test project with a simple crystal report. Note, I did not install the old component 13.0.12.2688 though on the new machine.

So, when I opened the existing project that was developed under VS 2013 with integrated CR for VS 13.0.12.1494 component from VS 2015 with integrated CR for VS 13.0.22.2668, Visual Studio gives me several errors, such as "CrystalDecisions.Windows.Forms.CrystalReportViewer is not defined",

"CrystalDecisions.ReportSource.ICachedReport is not defined"

"CrystalDecision.Shared.ExportOptions is not defined"

I cannot even open .rpt report file from VS Solution Explorer.

My question is what is the correct steps to upgrade my existing Visual Studio (VB.net) project (Crystal Report portion) from VS2013 with CR for VS 13.0.12 to VS2015 with CR for VS13.0.22

Thank you very much in advance for your help!
