When I open HMC and enter the auth key, it tells me that the auth key is invalid. I did everything required. Go to Search -> Windows Update Settings. Complete any updates you see here. Updates will be completed in half an hour. Restart after completion. Then run your browser and the program on the same computer. (If you copied the auth key from a different computer, it will not work.) Copy the auth key and paste it into the program. I did all of this and it didn't work.
