Unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib

[manofsteel00]

I am getting the following error message when trying to run a program over the network:

"An unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib.dll"

"Additional information: Request for the permission of type System.Security.Permissions.FileIOPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed."

First, I am not the author of the code. Second, I have Admin privilges to all network drives and am a Admin on MyComputer. I have googled the error to look for problems, and most said to change settings in the .NET Framework for .NET 1.1. I did; however, I still get the same error.

Private Sub cmdZone_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdZone.Click
        [B]odlgFreight.FileName = ""[/B] 
        Try
            If CheckCarrier() = True Then
                odlgFreight.Filter = "Text files (*.txt; *.csv)|*.txt;*.csv"
                If odlgFreight.ShowDialog() = DialogResult.OK Then
                    If odlgFreight.CheckFileExists = True Then
                        Try
                            CreateZones(odlgFreight.FileName, Me.cboShipType.SelectedItem, Me.cboCarrier.SelectedItem)
                        Catch ex As Exception
                            MessageBox.Show(ex.Message)
                        End Try
                        txtLog.Text = txtLog.Text & Now() & ": " & cboCarrier.SelectedItem & " Zones Created" & vbNewLine
                    End If
                Else
                    MessageBox.Show("Operation cancelled or other error", "File Selection", MessageBoxButtons.OK, MessageBoxIcon.Error)
                End If
            End If
        Catch ex As Exception
            MessageBox.Show(ex.Message)
 
        End Try
 
    End Sub

The executable is on a Network drive that I am an Administrator on. And the bold line of the code is where the error is thrown. Thank you for your time and help.

Go into your control panel -> administrative tools -> Microsoft .NET Framework 1.1 Configuration -> Runtime Security Policy

Then click on the "Adjust Zone Security" link on the right.

Click next when the first screen pops up, then on the second, click "Local Intranet" and increase its trust level to full trust.

See if that makes a difference.

Yeah, that's actually one of the things I have already tried. I just looked again, and it is still giving me that error
