Program can't access files in Program Files

In my program xPro I am having problems with it using files in it's directory in c:\Program Files(x86)\xPro. In one form it rights data to a .txt file when it closes. Everytime I try to close the program it says that access to the .txt file is denied. Any help?

Here is the code for Form Closing:

VB

TextBox2.Text = ""
        For Each thing As Object In ListBox1.Items
            TextBox2.AppendText(Trim(thing.ToString & vbNewLine))

        Next
        
        Dim SR As New StreamWriter(My.Settings.MyDirectory + "\Friends.txt")
        SR.Flush()
        SR.Close()
        Dim SR2 As New StreamWriter(My.Settings.MyDirectory + "\Friends.txt")
        SR2.Write(TextBox2.Text)
        SR2.Close()

I do now realize that I should add a Try statement but eitherway that doesn't exactly fix the problem.

On Windows7 the "Program Files" folder is protected by the UAC, so to write there you need administrator privileges (and the UAC confirmation).

It is better to write "data" to the user's local profile folders instead, use the Environment variable for this : http://msdn.microsoft.com/en-us/library/system.environment.specialfolder.aspx[^]

Access to the path 'C:\Program Files (x86)\xPro\Friends.txt' is denied.
Proper security privileges are not in place. You need to make sure that write permissions are in place. Further, if the text file is marked readonly, you cannot edit it until it is writable.
