I want to change the value of a registry key from 0x00000003 to 0x0000000. Here is the code I wrote to do it that doesnt work because rk is always null for some reason, I don't get it.

  RegistryKey rk = Registry.CurrentUser.OpenSubKey(@"My Computer\HKEY_CURRENT_USER\Software\Microsoft\Visio\Addins\mass.Connect");
           if (rk != null)
           {
               rk.SetValue("LoadBehavior", 0);
               rk.Close();
           }

Whats wrong here?

It should be:

RegistryKey rk = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Visio\Addins\mass.Connect");
           if (rk != null)
           {
               rk.SetValue("LoadBehavior", 0);
               rk.Close();
           }

You most likely don't have the rights to write to the registry. Is that correct?

Else give this a try:
RegistryKey rk = Registry.CurrentUser.OpenSubKey(@"HKEY_CURRENT_USER\Software\Microsoft\Visio\Addins\mass.Connect");

But that most likely won't work and it prolly is a registry security issue.
