Hello!  
I have a problem using licensed Ignition 7.9 on a Windows Server 2019. The installation goes without problems adding the supplemental modules also(Serial support gateway and client), but after I add the first Modbus RTU device, the gateway crashes and in the log appears the following error  
INFO | jvm 2 | 2024/06/05 15:27:23 | Serialio Library: version 10.2.3: build 9233  
INFO | jvm 2 | 2024/06/05 15:27:23 | Copyright (c) 1996-2015 [Serialio.com](http://Serialio.com), All Rights Reserved.

INFO | jvm 2 | 2024/06/05 15:27:23 | osName=Windows Server 2016 osArch=amd64  
INFO | jvm 2 | 2024/06/05 15:27:23 | Platform not supported, check VM properties os.name & os.arch

Is there a workaround to solve this?  
Thanks

Not in v7.9, no. IA switched to Fazecast's library in v8+, presumably because Serialio wasn't keeping up with modern platforms.

v7.9 **won't** be patched to fix this. Downgrade your Windows server if you really need this. Consider switching to Modbus RTU over TCP with a Moxa network serial converter.
