The attachment isn't a zip file, that looks like a System Information file. I've exlained again below but with more images:
Press the Windows key and the R button at the same time, which will open up the Run function, and then type in cmd:
View attachment 301382
And take note of where the C prompt is going to save it to. On mine, its C:\Users\My Name so that you can locate the file after.
Copy the below (the full line) and then go back to the Command Prompt, and press Ctrl V to paste it in:
reg export "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX" Epic Issue.reg
View attachment 301383
and press Enter.
Do this again for this key:
reg export "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\DirectX" Epic Issue second.reg
Now, navigate to the folder that it showed you on the Command Prompt. Like I said, mine is my Users folder, yours may be My Documents etc
Right-click on the files (as in select both together) and select 'Compressed (zipped) folder. And then upload that as an attachment.
