The Import Patch Data for Windows (PMImport) includes the Windows System Assessment Scan (WSAS) tool. This tool may fail to initialize or execute during the certificate validation phase of the WindowsPatchData.zip file. This prevents the generation of the Shavlik_applicability.xml file on client endpoints.
The following errors appear in the AeXNSAgent.log or STPatchAssessment.log:
ITMS 8.x
This issue occurs because the embedded signing certificates within the WindowsPatchData.zip have expired, or the datafeed migration (version 7.4) requires a newer assessment engine build to validate the content.
This issue is fixed in PMImport build 7.4.2019 and higher.
STPatchAssessment.exe (v7.4.2019+).If the issue persists, please see Contact Support. Scroll to the bottom of the page and click on your respective region.
