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.Tex*****ntains(" ")) { 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:

Run the program as Administrator ?

By building it, then go to the Projects folder.
>Run it from there?

Or is that what you tried?

Hmm, seems you have some administrator rights problems then O,o
-Sorry for not taking time to read it all before answering.
(Just woke up so

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.

I stopped the crashing, but @master131 your code doesn't seem to be working.
