CEF renderer process is not getting created on some OS

[sridhark]

Hi,
CEF renderer process is not getting created for windows 10 Pro systems. Its working fine on other OS. When I see the task manager one GPU process is getting created but renderer process is not created. How can I check this issue ? Do I need check the return value of CefExecuteProcess().

Does the issue reproduce with cefsimple/cefclient examples? See cefsimple example for how you should handle the value returned by CefExecuteProcess.

This is happening on the customer system so I can't ask the return value or ask him to run the cefclient.

Implement application logs that can be enabled via some switch. If something goes wrong CEF will log it, see CefSettings.log_severity and log_file.

Your renderer process most likely crashes. CEF has a built-in crash reporting system. For how to integrate it see:

Are these complete logs? I don't see anywhere "Failed to launch xxx process" log. What settings are you using? (all settings, switches, preferences).

Seems like you may be missing some binary files. (or maybe AV software deleted it)
