Running Windows 7 64 bit. I used the Windows installer on top of a running installation. Gateway “main” shows a “faulted” context even after a GCU restart. It appears that the whole Ignition context is failing to start due to an XOPC driver error.

What version did you guys upgrade from? Was it a “clean” upgrade – meaning you had no dev versions installed? ---

There may have once been a Dev version on this machine. The last working version was production. I haven’t touched it since the gateway failed to start. From an existing “install\_log.txt” that somehow didn’t get overwritten during the upgrade: [quote]Log started 03/28/10 at 12:38:34 Preferred installation mode : win32 Trying to init installer in mode win32 Mode win32 successfully initialized Executing C:\Program Files (x86)\Inductive Automation\Ignition/stop-ignition.bat Script exit code: 0 Script output: wrapper | Stopping the Ignition Gateway service… wrapper | Waiting to stop… wrapper | Ignition Gateway stopped.

Kevin, I had dev version 7.0.6, but then upgraded that to 7.0.9, then from 7.0.9 to 7.1 ---

Make sure that all of the modules are the same build number. You can check this in the gateway config section under Configuration -\> Modules. The build number is below the version, eg. b5058. If they don’t have the same build numbers you can download the modules from the current release downloads section of the website and install them manually. One thing to note, we renamed the OPC-UA drivers module to Allen-Bradley drivers. See if this fixes the issue. ---

I can’t get to the gateway config page. Is there a way to tell via the file system? As far as the AB driver, what file should I rename to what to attempt that fix? edit - I’ll try upgrading to 7.1.1 and see if that fixes it. ---

Running the 7.1.1 installer correctly upgraded all the modules and fixed the problem. Thanks 🙂
