Hello,

Using this code which I found on this web site to try to create a registry key to store an ID tag from my program:

Imports Microsoft.Win32

Public Class Form1
    Dim regKey As RegistryKey
 'Makes the key  
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        regKey = Registry.LocalMachine.OpenSubKey("Software", True)  
        regKey.CreateSubKey("MyAppV2")
        regKey.Close()
    End Sub

'Delete the key
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        
        regKey = Registry.LocalMachine.OpenSubKey("Software", True)  
        regKey.DeleteSubKey("MyAppV", True)
        regKey.Close()
    End Sub

'Read/write from key:
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Dim ver As Decimal
        regKey = Registry.LocalMachine.OpenSubKey("Software\MyAppV", True) 
        ' regKey.SetValue("AppName", "MyRegApp")
        ver = regKey.GetValue("Version", 0.0)
        If ver < 1.1 Then regKey.SetValue("Version", 1.1)
        regKey.Close()
    End Sub
End Class

But when the program runs (any of the 3 buttons) I get an error message "When deploying an Office solution, check to make sure that you have fulfilled all security requirements"
The vb project is set as a "Full trust application". The program is running in Vista.

Any thoughts on what I might be doing wrong or missing?

THANKS
