  you need FastReport.DB2.dll only if fastreport designer directly connect to database (you create datasource in fastreport designer)
  
  alternatively, make sure "IBM Data Server Provider for .NET" is working, try to connect dotnet application to db2, this code will open designer from your dotnet application
  

              Using cnn As New OleDbConnection(mySQLConnString)
                  cnn.Open()
  
                  Using cmd As New OleDbCommand()
                      cmd.Connection = cnn
                      cmd.CommandType = CommandType.Text
                      cmd.CommandText = "SELECT * FROM qryPrintSuspend"
                      cmd.Parameters.AddWithValue("@selID", argID)
  
                      Using dr As OleDbDataReader = cmd.ExecuteReader()
                              Using dt As New DataTable()
                                  dt.Load(dr)
                                  dt.TableName = "MainReport"
  
                                  report.Load("PrintSuspend.frx")
                                  report.FileName = "Print Temporary Transaction"
                                  report.RegisterData(dt, dt.TableName)
  
  
  
                                  'you need this code to open the designer and use datasource from code
                                  report.GetDataSource(dt.TableName).Enabled = True
                                  Dim band1 As FastReport.DataBand = CType(report.FindObject("Data1"), FastReport.DataBand)
                                  band1.DataSource = report.GetDataSource(dt.TableName)
                                  report.Design(True)
  
  
  
                              End Using
                      End Using
                  End Using
              End Using

  i use google to translate your picture of errors, but the popup error can't tell a story. My guess:
  1. IBM Data Server Provider for .NET instead of FastReport.DB2.dll
  2. learn how to push datasource from .net code to fastreport
  3. resolve complex query in stored procedures, call stored procedures from .net code, push single 'select query' to fastreport
