My Crystal Report reports does not work in test mode

I’ve installed Crystal Reports on my Visual Studio 2017. It works fine in design and preview mode but in test mode I get the following error.

An unhandled exception of type 'System.InvalidCastException' occurred in CrystalDecisions.CrystalReports.Engine.dll

Unable to cast COM object of type 'CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass' to interface type 'CrystalDecisions.ReportAppServer.Controllers.ISCRReportSource'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{98CDE168-C1BF-4179-BE4C-F2CFA7CB8398}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

How to solve this ???

    CR Designer no longer installs the .NET SDK's.

    Go here for the download link and other info, and PLEASE read all of the info, you do need to to get it installed properly.
