The latest versions of Reviver since 2.4.4 don’t require this workaround.
On two (of three) machines that I recently upgraded to Windows 10 build 10061, I got error code 8004882a when I tried signing into Messenger The error is somewhere in the authentication process, but the error doesn’t make much sense (The partner DNS used in the login request cannot be found). In the process of investigating the problem, I managed to fix the issue but I’m not entirely sure what the problem is yet as I haven’t been able to reproduce the problem again. Regardless, if you’re experiencing the problem, you can try this fix too and report your results. Firstly, you’ll need Windows Photo Gallery installed. If you don’t already have it installed, download the Windows Essentials Installer, select the Choose option, choose the Photo Gallery and Movie Maker option and click Install. Then just start Windows Photo Gallery and make sure you are signed in in the top corner with your Microsoft account. After that, try signing into Messenger again. Hopefully this can be studied further, so far I’ve come up empty trying to get the problem to resurface on new installs.
