Hi, I have installed the AWS Injector module (Cirrus Links). The module is in in faulted state since the install. I have tried un-installing and re installing the module and re started the gateway. I have 7.9.1 on 64 Bit Windows 7. Any ideas what I should be looking at? The MQTT Engine module installed properly and was running. Thanks ---

What error is displayed, if any? If you don’t see one on the status page, head to Diagnostics -\> Logs just after restarting the module. ---

With a ClassNotFoundException it’s likely that the module isn’t compatible with 7.9.1. I believe the module was released fairly recently, so Cirruslink may have only built it against newer versions of 7.9. ---

In the past, I have had to restart the AWS module right after installation/updates for it to work… I would try that if you haven’t already.
