Crystal Report SP26 SetDataSource() Method failed in computers of clients in Visual Studio 2019

​I'm working on Visual Studio 2019 and Crystal Report Service Pack 26. My code read data into ADO.NET dataset and I set those datases as datasourse of my reports. something like this in Visual Basic.Net:

    Dim ds1 As New DataSet1()

    Dim myRep As New CrystalReport1
    taAccArticleFields_TBL.Fill(ds1.AccArticleFields_TBL)
    myRep.SetDataSource(ds1)
    crvReport.ReportSource = myRep

When I run program through VS all is good and reports show without error. But when I want to run my program on another computer which only has CR26 runtime installed, it gives an error on calling SetDataSource method for report as below:

System.Runtime.InteropServices.COMException (0x800002CD): Error in File temp_04020c6d-5b84-40d9-8558-bf87b6d5e554 4840_5464_{1C1D3ACF-9F25-45E2-B0EE-BB77F1DDA6B6}.rpt: Failed to load database information.

at CrystalDecisions.CrystalReports.Engine.Table.SetDataSource(Object val, Type type) 
at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type)

I encounter this with any program I write. Does anyone have idea to solve this?

Solution

  • Thanks to @Julie I found missing file need to run ADO.Net report using Crystal Report SP26. Unfortunately, When you install SP26 run-time it doesn't copy crdb_adoplus.dll file which need to Crystal Report to load data from ADO.Net dataset.

    Here is the solution:
