It looks like due to low permission this thing is happening. For that there is a small fix that might help you to some extent. For that go on Control Panel and then click on Local Security Settings. In that look for Software Restriction Policies. Double click on Enforcement and choose Apply Software Restriction. Check that you allow all users there. This would give the admin rights to run patches and software in your system. I hope this would be the only issue. About patches I am not sure whether they work or don't work on different hardware architecture.

Thanks for that answer. It really worked for me. I had seen the settings before and was not able to locate any software restrictions. If you are still confused with the settings then you can find the same under Performance Maintenance > Administrative Tools > Local Security Policy > Software Restriction. You just need to double click to create one and set a fresh policy. That's all. Then try back to run the patch it would work.
