Registry Access Help
When I press a button my program attempts to give full control of a registry key to the group everyone, the registry key has denied rights so you can't modify it which is the point of the program. When I try to press the button with the program run as administrator I get this error: Requested registry access is not allowed. Heres the coding for the button:
Code:
        private void btnFixReg_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(txtChangeKey.Text))
            {
                MessageBox.Show("Please enter a key!", "Error:", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            else
            {
                if (txtChangeKey.Text.Length < 44 || txtChangeKey.Text.Length > 44)
                {
                    MessageBox.Show("Invalid key format entered!", "Error:", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }
                else
                {
                    if (txtChangeKey.Text.Contains(" "))
                    {
                        MessageBox.Show("Your entered key contains spaces!", "Error:", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    }
                    else
                    {
                    string enteredkey = txtChangeKey.Text;
                    RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA", true);
                    if (key == null)
                    {
                        MessageBox.Show("ArmA 2 Operation Arrowhead is not installed!", "Error:", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    }
                    else
                    {
                        RegistryKey key7 = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA", true);
                        RegistrySecurity userSecurity = new RegistrySecurity();
                        RegistryAccessRule userRule = new RegistryAccessRule("Everyone", RegistryRights.FullControl, AccessControlType.Allow);
                        userSecurity.AddAccessRule(userRule);
                        byte[] buffer2 = new byte[15];
                        string[] strArray2 = enteredkey.Split(new char[] { '-' });
                        int upperBound = strArray2.GetUpperBound(0);
                        byte[] buffer3 = new byte[upperBound + 1];
                        int num3 = upperBound;
                        for (int i = 0; i <= num3; i++)
                        {
                            buffer3[i] = Convert.ToByte(strArray2[i], 0x10);
                        }
                        buffer2 = buffer3;
                        key.SetValue("KEY", buffer2);
                        RegistryKey key2 = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA", true);
                        byte[] objectValue = (byte[])RuntimeHelpers.GetObjectValue(key.GetValue("KEY"));
                        string str2 = BitConverter.ToString(objectValue);
                        byte[] buffer = (byte[])RuntimeHelpers.GetObjectValue(key.GetValue("KEY"));
                        string str3 = BitConverter.ToString(buffer);
                        str3 = BitConverter.ToString(objectValue);
                        RegistryKey key5 = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA", true);
                        byte[] buffer5 = (byte[])Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Bohemia Interactive Studio\ArmA 2 OA", "Key", null);
                        string str = BitConverter.ToString(buffer5);
                        MessageBox.Show("Your registry has been fixed and your ArmA 2 Operation Arrowhead Key has been set to: " + (enteredkey), "Success:", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
                    }
                    }
                }
            }

        }

You need to open the sub-key initially like this:
Code:
RegistryKey key7 = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA", RegistryKeyPremissionsCheck.ReadWriteSubTree, RegistryRights.ChangePermissions | RegistryRights.ReadKey);
See if that works.

Didn't work, I replaced:
RegistryKey key7 = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow643 2Node\Bohemia Interactive Studio\ArmA 2 OA", true);
With: RegistryKey key7 = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow643 2Node\Bohemia Interactive Studio\ArmA 2 OA", RegistryKeyPremissionsCheck.ReadWriteSubTree, RegistryRights.ChangePermissions | RegistryRights.ReadKey);
And it's still giving me the error: Requested registry access is not allowed.

Code:
var arma2Key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA", RegistryKeyPermissionCheck.ReadWriteSubTree, RegistryRights.ReadPermissions | RegistryRights.ChangePermissions);
            
if (arma2Key != null)
{
    var userRule = new RegistryAccessRule("Everyone", RegistryRights.FullControl, AccessControlType.Allow);
    var userSecurity = arma2Key.GetAccessControl();
    userSecurity.AddAccessRule(userRule);
    arma2Key.SetAccessControl(userSecurity);
}
Just tried that and it worked.

It's giving me the same error: Requested registry access is not allowed.
Here's the details:

To enable just-in-time (JIT) debugging, the .config file for this

The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer

Hmm, seems you have some administrator rights problems then O,o

Try to use it on some other PC, create a fake registry value, and text

I can edit registry keys fine, just when I deny access to the registry key then attempt to use the program to unlock it it crashes.
