Summary

Customers experienced an issue with their application due to unsigned FNP DLLs in the latest release. They reported receiving the following error message in their logs when starting their application:

The digital signature of the Xalan-C_1_12.dll is not matching. Thus, the application cannot be started.

Xalan-C_1_12.dll

All prior versions of these DLLs were digitally signed, indicating a change in the latest release that is causing the application to fail to start due to mismatched digital signatures.
