Because the UI of SPE uses Java, additional steps may be required to permit Internet Explorer to open the UI, as noted here:
https://knowledge.broadcom.com/external/article/165237/how-to-enable-the-console-with-protectio.html

Without the UI, configuration and administration tasks are accomplished via xmlmodifier or through registering SPE with the CWP portal. For more on these topics, see:

Also, note that while BROADCOM has not officially certified Protection Engine for use on Windows 2019, SPE for NAS 8.0.0.44 is observed to install on Windows 2019 with no known issues.
