mcsMQTT disappeared on its own

[cjin]

I have been running mcsMQTT (think it is version 5.13.x but might be 5.14.x) with HS3 on a Win10 machine. I only use mcsMQTT for 2 things: 1) chart a few thermometers in HS3, 2) communicate between HS3 and a standalone mcsSprinklers.

Everything worked fine for a long time, then I noticed an error messages from mcsSprinklers complaining about MQTT broker not found. Turns out mcsMQTT plugin just disappeared as if it was not installed with HS3. Nothing has been changed in the system for months, except Win10 security updates.

Any idea what might be causing this? I guess I could try reinstall mcsMQTT plugin, just would like to understand what caused this problem at the first place...

I am not aware of anything that could cause HSPI_MCSMQTT.exe being deleted. Maybe antivirus program quarantined it due to some bit pattern match. I have never seen this happen.

Thank you Michael. HSPI_MCSMQTT.exe is indeed missing from HS3 directory, there is only HSPI_MCSMQTT.exe.config. File mcsMQTT.dll is still in HS/bin/mcsMQTT directory. I reinstalled the plugin, it seems to be working ok so far.
