Logfiles to be sent for bug investigation


In those cases when there are a lot of items in the logfiles it's hard to identify, which logfiles item belongs to the current issue. In these cases the Windows logs generated in the "Event Viewer", because when a crash is happening on a computer it creates a new comment in the Event Viewer, which can opened by typing "Event Viewer" to the windows search bar.



1. On the left side, please select "Windows Logs", then from the right menu select "Filter current log" and check-in "Error" check-box to see only errors listed among Windows Logs.



2. This way only those events will be listed, which caused an error in operation, eg. an application crash.

3. The last step is to save the logs for these filtered events. To do this, please select "Save selected events".



4.  Type a filename, save the log and send it to jc4o-support@chemaxon.com.
