Uac kapatma c#

I try to change my own program setting in registry, and it works well under Vista, Win 7 (UAC enabled). It just has error when running under Win8 (UAC enabled).
Thank you for your suggestion, I'll take a look at serialization.
Additional, this is my code

1	RegistrySecurity rs = new RegistrySecurity();

2	RegistryKey rk = Registry.ClassesRoot.OpenSubKey(subkey, RegistryKeyPermissionCheck.ReadWriteSubTree, RegistryRights.FullControl); // Opens the key again with full control.

3	rs.SetOwner(new NTAccount("newAdmin"));// Set the securitys owner to newAdmin

4	rs.SetAccessRuleProtection(true, false);

5	rk.SetAccessControl(rs);// Set the key with the changed permission so Administrator is now owner.
