I deployed a Windows 8.1 update x64 machine with Office 365 and the office 2016 apps.
The following error message appeared when starting Skype for Business Recording Manager:
When you see this error, it might be, that you have the Windows N version installed. This means, the media feature pack is missing, and Skype for Business Recording Manager needs it to work correct.
To solve this issue, install the windows 8.1 media feature pack ( KB2929699).

After installation of the pack, Skype for Business Recording Manager works just fine.
Until next time.
