Error upgrading to SP26 in Visual Studio 2019

[former_member657844]

The type 'ReportDocument' exists in both 'CrystalDecisions.CrystalReports.Engine, Version=13.0.4000.0' and 'CrystalDecisions.CrystalReports.Engine, Version=13.0.2000.0' in CrystalFormViewer.cs.

In my winforms.proj file (.net v4.7.2) I see a reference to Version=13.0.4000.0 but I can't find a reference to 13.0.2000.0 anywhere in the solution. I also have a v4.7.2 class library referencing 13.0.4000.0.

I deleted the bin and obj directories in both projects and still get this error.

I cannot build and run the application. This is urgent.

I have no idea what the ticket number is. All I have are 20 emails from SAP saying "Neither CIC nor our team is an expert on the software" - whatever that means. After paying so much money and still getting no support, I am left very angry.
