For 2005 you could do:

VB Code:

If My.Computer.FileSystem.DirectoryExists("C:\Program Files\") Then
            MessageBox.Show("It's located in C drive")
        ElseIf My.Computer.FileSystem.DirectoryExists("D:\Program Files\") Then
            MessageBox.Show("It's located in D drive")
        Else : MessageBox.Show("Couldn't find it at all!")
        End If

For 2003, use:

system.IO.Directory.Exists(etc...)

VB Code:

System.Environment.SpecialFolder.ProgramFiles
