BF1942 not launching, as well as other games failing to install, error 327682:11

Hey there @rowlY_au

327682 error at least is a connection-based error. The best advice I could give is running both the Origin and the games as an administrator, ensuring no firewall or other security programs are getting in the way, and ensuring you have the necessary administrator rights in the first place.

So first of all, do ensure you're an administrator on your own computer: https://help.ea.com/en-us/help/pc/how-do-i-run-a-program-or-a-game-as-an-administrator/

You've said that you've made quite a bit of troubleshooting already such as creating exceptions to your anti-virus, but do give the Connection Issue topic a read as well. Could be that you may need to add ports to your firewall for example: http://answers.ea.com/t5/Technical-Issues/Complete-Support-Origin-Connection-Issues/td-p/5019298

As for the rest of the errors, I can't unfortunately really tell by those generic errors what could be the cause of the problem. Could you post a DxDiag and perhaps I could help with the information that provides, or perhaps someone else would have a clue ? https://help.ea.com/en/help/pc/how-to-gather-dxdiag-information/
