If you're asked to provide a WER report as an attachment to a Helpdesk ticket, this is how to find that file we require.
If you do not remember the time you had the GMS2 issue, then go ahead and recreate the crash in GMS2 just now before carrying on with these steps, otherwise you will need to search your events list for the previous crash instance. Note also that Windows does clean up the log folders after a while, so you may find the files are now gone and you need to recreate the error anyway.
Using Event Viewer
If you right-click your Windows start button you will find Event Viewer near the top of the context menu which appears.
Left-click this, and the Event Viewer application will shortly appear. Note that there may be a slight delay after it has loaded before the application is really usable, as it has to process your logs for all Windows events.
In the tree on the left, click to expand "Windows Logs", then select "Application". You should see something like the image below.
You can see that we have two Errors and immediately above that, two Information entries about those errors.
It's typically the top Information entry that we want to check first (the one from 17:16:32), as this is the one in which Windows had the most information about the issue and was ready to send the log to Microsoft if you let it.
Click this entry in the list and the panel below will change to show the contents of the event log. Which will be something like this:
The file we want is hopefully at the location highlighted above.
Note that in the example above, we are on a domain/networked machine and so Windows adds in an undesired "\\?\" at the start of the path, which will break the ability to simply click the link to open the folder in Explorer.
If you do not have this bit at the start of your path the link should be clickable. However, if clicking the link does not open a valid folder in Explorer, copy the required portion of the link via Ctrl+C, Windows key + R to open the Run window, then Ctrl+V and enter to make Explorer open the folder.
I Don't Have The Folder/File
If Windows says the folder is gone or there is no .wer file in the folder, then you will need to recreate the issue in GMS2 to generate a new error log and report file. You can refresh the event list after doing this by simply clicking the Refresh button in the right-hand panel:
Okay, Got The File...
Once you have found the file, feel free to open it in Notepad or some other text editor and take a look at what the error says happened. If you know the file(s) being blamed relate to something you can investigate yourself - such as one of your device drivers or a protection software in use on the machine - go ahead and try to resolve the issue yourself. However, even if you do fix your issue, we would still like you to reply to the ticket and send us the log file along with how you fixed the problem.
Attach the .wer file to your ticket via dragging it onto the ticket when viewed in your browser or email client, add in your relevant comment, and then send your reply back to us.
Please do not copy/paste the contents of the log into your reply, as pasting in large logs just makes the ticket hard to read. Thanks.
