We got crash when using MIP in development. Our ANPR plugin works well most ot the time, crash on end user's side. The following can show you the details.

When we are using alarmClient.UpdateAlarm(aAlarm.Id, “”, 4, 1, DateTime.UtcNow, “”); It crash. You can see the details from attached screenshot, thank you in advance.

Hi. Which version did you use when you experienced this error? Please tell us about your XProtect version/edition and MIP SDK version.

MIPSDK_Installer_2017R2.msi

Essential+ 2019 R2

System Licence feature “ManageAlarms” is not enabled. That’s why you get crashing.

What Andreja is saying in other words is that XProtect Essential+ does not support alarm management..

I am guessing that this means that your integration will not work for customer using XProtect Essential+.
