Symptoms:
When Lenovo Patch is installed into the SCCM console on a Windows 10 computer, initial attempts to connect to the WSUS Server returns the below error message on screen:

To further verify the issue, review the Lenovo Patch.log file in the C:\Users\\Lenovo\Lenovo Patch folder. The log file will have the following information to determine if this KB Article is applicable:
Exception: System.DllNotFoundException Unable to load DLL 'SusNativeCommon.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
Cause:
Lenovo Patch uses the SusNativeCommon.dll as part of the WSUS API for communication with WSUS and the management and publishing of updates. There have been issues with Windows 10 computers missing SusNativeCommon.dll under the C:\Windows\SysWow64 folder.
Resolution:
Copy the SusNativeCommon.dll from the C:\Windows\SysWow64 folder on the WSUS Server which is being connected to, and move it to the C:\Windows\SysWow64 folder on the Windows 10 computer.
This does not guarantee to allow Lenovo Patch for SCCM to publish updates! If Lenovo Patch is on a Windows 10 computer and connecting to a WSUS Server that is not Windows Server 2016, Lenovo Patch will not be able to publish updates due to the WSUS API versions not matching!
Additional Information:
This KB Article outlines a known issue using Lenovo Patch for SCCM on Windows 10 computers. The resolution will only address connecting to the WSUS Server, if the WSUS server is not on Windows Server 2016. While an administrator will be able to manage published updates from an SCCM Console installed on a Windows 10 computer, an administrator will not be able to publish new updates. Microsoft only allows Windows 10 SCCM consoles to publish to WSUS on Windows Server 2016.
