Hi there,

We are having an issue with a project in Visual Studio 2017 when attempting to open reports.

This is the error shown in Visual Studio:

Exception thrown: 'System.Runtime.InteropServices.COMException' in CrystalDecisions.ReportSource.dll

What am I missing here?

Select each of the Crystal references in your project. In the properties, there is an option called "Embed Interop Types". By default, this is set to True, but it needs to be False for your application to run. Also, you need to make sure that you're using the full version of the .NET framework, not a client or core version.
