Patch Connect Plus also supports the V3 format of third-party catalogs.


The publishing of updates for certain third-party applications, (Ex: 7-Zip) may fail since they fall under the category of open-source applications. While publishing patches for similar open-source applications, Patch Connect Plus provides you with a self-signed certificate that you can add to SCCM, so that patches do not get blocked. Download the Patch Connect Plus self-signed certificate. Once this certificate has been downloaded, it has to be imported to the SCCM machine's Certification Authorities Store (local computer account) under Trusted Publishers and Trusted Root Certification Authorities. 

Once the certificate has been imported, patches can then be published to SCCM. Additionally, to find the imported certificate, open the SCCM console, navigate to Administration > Security > Certificates. Here you can find the certificate named as Patch Connect Plus SCUP. Also note that this one-time certificate import ensures all updates for open source applications get signed before they are published to SCCM.
