Our client's server admin is attempting to upgrade one of their environments from 2013 SP1 to 2013 SP1 HR1. Upon running the installer the following error occurs.
The logs show this message:

I've looked at a some generic Windows help articles: https://support.microsoft.com/en-us/kb/834484
Also found this, Solution 2: http://www.helptouser.com/tridion/7487-unable-to-load-config-file-cm-cnfg-git-unable-to-decrypt-data.html, and this looks like the answer, but I'd like a bit more information on it.
