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

Question

?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?

感谢@Julie，我发现缺少文件需要使用 Crystal Report SP26 运行 ADO.Net 报告。不幸的是，当您安装 SP26 运行时时，它不会复制crdb_adoplus.dll文件，该文件需要 Crystal Report 从 ADO.Net 数据集中加载数据。

这是解决方案：

• 在 32 位操作系统中：您必须将 crdb_adoplus.dll 文件从开发人员计算机的以下文件夹复制到客户端计算机：

  C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86

• 在 64 位操作系统中：您必须将 crdb_adoplus.dll 文件从开发人员计算机的以下文件夹复制到客户端计算机：

  C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win64_x64

  并且它工作正常。我希望SAP在未来的服务包中解决这个问题。
