+# Unable to find an entry point error when updating SQL Server 2022
+
+This article documents an issue where applying a SQL Server 2022 Cumulative Update (CU) from the commmand line generates an error message.
+
+_Applies to:_   SQL Server 2022 on Windows  
+
+## Symptoms
+
+Consider the following scenario:
+
+- You have a computer that's running an OS that has an earlier build of the Windows OS than Windows 10 Build 20348, such as Windows Server 2016 or Windows Server 2019.
+
+- You try to apply a CU to SQL Server 2022 using **setup.exe** from the command line
+
+In this scenario, an exception occurs in the setup console during the update process, displaying the following error message:
+
+> System.EntryPointNotFoundException: Unable to find an entry point named 'GetNumaNodeProcessorMask2' in DLL 'kernel32.dll'
+
+## Cause
+
+When the **setup.exe** runs on an OS version where the [GetNumaNodeProcessorMask2 API](/sdk-api/sdk-api-src/content/systemtopologyapi/nf-systemtopologyapi-getnumanodeprocessormask2.md) is unavailable, an exception appears in the setup console.
+
+## Resolution
+
+No resolution is necessary as the exception does not affect the setup behavior or update outcome.
+
+## More information
+
+This exception is only visible in the setup console when running **setup.exe** from the command line.
