Dear AMD Community,
with a brand new Windows 10 System with a Ryzen CPU it was not possible to use a digital signature with Outlook 2016/2019. The Problem is described in detail here: Signatur mit S/Mime-Zertifikat in Outlook 2016 schlägt fehl - Microsoft Community
Microsoft found the issue in cooperation with the users which have the issue. Solution is to delete the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Cryptography\Providers\AMD Provider] key in the registry.
Reason for that is the missing amdumcsp.dll which should be located in C:\Windows\system32.
Can someone from the AMD Stuff confirm this and provide the amdumcsp.dll for Windows 10? Just with this DLL S/MIME will work on Windows 10 with Ryzen CPU / AMD Chipset out of the box.
Thank you very much
maybe it is possible that an AMD Software Engineer can have a look into this problem? That would be very nice. Sure, the problem is solved now with the workaround i described, but the reason for this issue is still present. On every fresh installed Windows 10 machine with a AMD Ryzen CPU and Office 2016/2019 with S/MIME configuration the error occurs.
So please take a look into this. I think this is a small thing for AMD to provide the missing DLL.
Thanks, ronaldb, you are welcome. Yours is the first inquiry on this subject I have seen. Please let us hear what you learn. Enjoy, John.
i also ran into this problem - but with the latest Outlook version 2021.
I deleted the AMD CSP registry entry and restarted my PC but still the same error message.
Does anyone have news for this issue?
