SCCM and Cert

Hi Experts,

I have an issue with SCCM and the 3rd party tool PatchMyPC.
There is an issue with the certificate.

See the log:

There was an error when attempting to save WSUS signing certificate configuration. Will retry on next sync. Exception: System.ComponentModel.Win32Exception (0x80004005): %1 is not a valid Win32 application~~   at Microsoft.UpdateServices.Internal.BaseApi.SoapExceptionProcessor.DeserializeAndThrow(SoapException soapException)~~   at Microsoft.UpdateServices.Internal.DatabaseAccess.AdminDataAccessProxy.ExecuteSetSelfSigningCertificate()~~   at Microsoft.UpdateServices.Internal.BaseApi.UpdateServerConfiguration.Save(Boolean detectConfigChange)~~   at Microsoft.SystemsManagementServer.SoftwareUpdatesManagement.WsusSyncAction.WSyncAction.TriggerWsusNewSigningCertificateCreation()

Open in new window

On the WSUS the cert is self-signed and valid until 2023.

Do you have any ideas ?

Did you import your self-signged WSUS certificate to the SCCM server's  Computer -> Trusted Root Certification Authorities store?

We also used client helath.
But the client was also installed on the SCCM server itself.
We removed the client and it worked again.
