在具有管理员权限的Vista/7上，regedit和副本的调用以静默方式失败

我正在尝试在使用C#的机器上设置支持信息。我有一个注册表文件要导入（我也尝试过使用Microsoft.Win32，下面的代码注释了进程调用），还有两个文件要复制到system32中。文件位于共享上，代码的其他部分与共享正确交互。第一个代码，所以我可能离这里很远

try
                {
                    //String pathtooemreg = Environment.ExpandEnvironmentVariables(@"%HOMEDRIVE%'Windows'System32'oeminfo.reg");
                    //System.IO.File.Copy(@"''files'tools'oeminfo.reg", (pathtooemreg), true);
                    //Process p = new Process();
                    //p.StartInfo.FileName = @"regedit";
                    //p.StartInfo.Arguments = " /s" + (pathtooemreg);
                    //p.StartInfo.UseShellExecute = true;
                    //p.StartInfo.CreateNoWindow = true;
                    //p.EnableRaisingEvents = true;
                    //p.Start();
                    //p.WaitForExit();
                    Registry.SetValue("HKEY_LOCAL_MACHINE''SOFTWARE''Microsoft''Windows''CurrentVersion''OEMInformation", "Model", "");
                    Registry.SetValue("HKEY_LOCAL_MACHINE''SOFTWARE''Microsoft''Windows''CurrentVersion''OEMInformation", "Manufacturer", "somecompanyname");
                    Registry.SetValue("HKEY_LOCAL_MACHINE''SOFTWARE''Microsoft''Windows''CurrentVersion''OEMInformation", "Logo", "oemlogo.bmp");
                    Registry.SetValue("HKEY_LOCAL_MACHINE''SOFTWARE''Microsoft''Windows''CurrentVersion''OEMInformation", "SupportPhone", "somephonenumber");
                    Registry.SetValue("HKEY_LOCAL_MACHINE''SOFTWARE''Microsoft''Windows''CurrentVersion''OEMInformation", "SupportURL", "someurl");
                    Registry.SetValue("HKEY_LOCAL_MACHINE''SOFTWARE''Microsoft''Windows''CurrentVersion''OEMInformation", "SupportHours", "");
                    String pathtooeminfo = Environment.ExpandEnvironmentVariables(@"%HOMEDRIVE%'Windows'System32'oeminfo.ini");             
                    System.IO.File.Copy(@"''files'tools'oeminfo.ini", (pathtooeminfo), true);
                    String pathtooemlogo = Environment.ExpandEnvironmentVariables(@"%HOMEDRIVE%'Windows'System32'oemlogo.bmp");
                    System.IO.File.Copy(@"''files'tools'oemlogo.bmp", (pathtooemlogo), true);
                    listBox1.Items.Add(@"3b.Done Installing OEM/Support info.");
                }
                catch (Exception err)
                {
                    MessageBox.Show(this, "Error: " + err.Message);
                }
