One of our clients did a windows patch update, late night, now the ignition server wont start. Has anyone seen this error before? ![error](https://us1.discourse-cdn.com/inductiveautomation/original/2X/a/abca05861127d0c0686c5f3134a091f9a5da0729.png) ---

Which Ignition version are they running? I believe there was an Ignition version affected something like that by a Windows update–resolved by upgrading Ignition. ---

ignition 7.9. IT found out that it looked like some reference to java was corrupted. They reinstalled Java and everything started up. Thanks
