I am currently trying to implement a custom credential provider on Windows 8.1. I downloaded the sample from https://code.msdn.microsoft.com/windowsapps/V2-Credential-Provider-7549a730. I copied the dll to C:\Windows\System32 and used the included register.reg for registering the dll. I can see all entries in the registry.
If I restart my computer I can't see any new credential providers. What do I miss? I assume that it doesn't matter whether the system is in a domain or not?
Copy the dll's msvcr120.dll and msvcr120d.dll into the C:\Windows\System32 folder.
