Question

I am developing an addin for Outlook 2010 with Visual Studio in C#.
I created a custom ribbon with a button. Once you click the button, it loads a form where you can generate a special appointment.
It works great on my development computer. But when I install it on another computer (without Visual Studio, but with installed .net framework and vsto), the ribbon with the button loads, but the creation of the form instance fails.

I have created a form in my Project named frmBZAppointment. This is my button onclick listener (which works perfect on my dev pc, but not on another pc)

public partial class CustomerRibbon
{
    private void butCustomAppointment_Click(object sender, RibbonControlEventArgs e)
    {
        MessageBox.Show("test 1"); //works
        frmBZAppointment frm = new frmBZAppointment();
        MessageBox.Show("test 2"); //does not work
        frm.Show();
        MessageBox.Show("test 3"); //does not work
    }
}

I’ve already finished this guide

It would be great if someone has an idea what it could be.

EDIT:

solved the problem

I had to add “Microsoft Visual Basic PowerPacks 10” to my installation prerequisites.

Try this:

public partial class CustomerRibbon 
{ 
    private void butCustomAppointment_Click(object sender, RibbonControlEventArgs e) 
    { 
        try
        {
            frmBZAppointment frm = new frmBZAppointment(); 
            frm.Show(); 
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message); 
        }
    } 
}
