I wanted to share a fix to the EOS-ERR-1603 error that some experience with the Epic Games Launcher and Online Services Install that I haven't seen elsewhere and I hope might be useful.
I followed all of the steps detailed here with no luck: https://www.epicgames.com/help/en-US/epic-games-store-c5719341124379/error-codes-c5719359691291/eos-err-1603-a5720340831259
Various forums suggested the issue may be due to installing the launcher on a different drive, but mine is in the default location on C:\ so no joy with that either.
However I noticed in the registry there were entries pointing to "C:\Program Files (x86)\Epic Games\Epic Online Services" but the deepest folder didn't exist in my installation, so I created the folder "Epic Online Services" under the "Epic Games" folder:
I then re-ran the installer as described in step 6 on the Epic page linked to above, which in my case is C:\Program Files (x86)\Epic Games\Launcher\Portal\Extras\EOS\EpicOnlineServices.msi and the installer ran successfully fixing the issue.
Hope this helps someone.

C:\Program Files(x86)\EpicGames\Launcher\Portal\Extras\EOS and then there is the Epic Online Services Installer and when i click it something downloads bit when its done nothing happened at all
Thank you, I was trying to go around uninstalling and reinstalling for a couple of hours to no avail before I found your solution.
Everything's working well now, so thank you!
Thanks a lot, Jonas!
Finally something that worked for me!
That was a clever workaround.... hahaa
This was the correct answer in 2023 on Windows 11.. Thank you
I tried this but when I click on the installer, it starts installing but then comes up and error that says: Error writing to file: C:\Program Files (x86)\Epic Games\Epic Online Services\EpicOnlineServices.exe. Verify that you have access to that directory.
I have checked everything and I do have access to the Epic Online Services, as I am the PC administrator, so why isn't this working? Has anyone else had this issue?
