Ryzen CPU and Outlook 201x s/mime encryption and digital signature not possible

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 Providerkey 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

Kindly Regards

Ronald

Hi,

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.

Thank you

Kind Regards

Ronald

ronald, please open a support ticket here.  This is a user forum (almost no one works for AMD) and I think you need to talk to AMD directly.  Good luck and enjoy, John.

Hello John misterj,

thanks for the information. My fault! But maybe another user have the same issue so they have now a topic here. 

I will open now a support ticket. Thanks for the link.

Bye

Hi all,

 

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?
