I have a customer whose Vision Client Launcher (8.1.32) is failing to launch any client due to the following error. Details is greyed out. We have cleared cache. Uninstalled / Reinstalled. Still the same issue. Any ideas would be appreciated.
You can get more information (usually) if you look at your vision client launcher's log file, extract the java command at the end that it uses to launch the real client, and run that manually in a terminal. Then you will likely see everything that is going wrong.
Is it actually failing to launch (there sure appears to be a client in the background of your screenshot), or is this error just appearing and then the client starts the rest of the way up?
JxBrowser failing to launch is not fatal to the client launch as of some recent version, though it's possible it appears to be failing if you're embedding a web browser component on one of your initial startup window(s).
So the app does run, but there is no window that starts up with the WebBrowser module. There is a window that can be clicked on that has the WebBrowser embedded. This doesn't happen on other client machines. Would there be a particular reason why it wouldn't work on one machine vs another?
There might be a more useful error message in that particular client's diagnostics console (Ctrl + Shift + F7). From experience, it's usually some failure to extract temporary files caused by antivirus/OS file permissions/cosmic rays/whatever.
I forgot about the details of the ticket I alluded to - if you're using the web browser module at all, we do attempt to initialize it as soon as the client launches, for faster startup once you actually navigate to a window that uses the component. That process happens in the background and is normally silent, unless something goes wrong.
In my client logs, I have a ERROR designer.JXBrowserUtil -- Could not initialize browser Engine, platform is not supported.
The client here is running on Win2012R2 (soon to be upgraded), but is this the issue?
Yes, Google dropped support for Windows 2012 in Chrome/Chromium.
