The solution to the problem of EOS-ERR-1603. In fact this problem comes when we install it on a hard drive other than C.

Solution :

To solve the problem when you want to install the launcher on a hard drive other than The C:

• Install it normally on the C disc: 'Program Files' (x86) Epic Games
• In the folder there is DirectXredist / Laucher / Epic Online Services
• Just create on the disk that you want to put epic games a folder of the name Epic games and move the folder DirectXRedist and Launcher in Example makes a folder in D: Games-Epic Games and paste the 2 folders.
• Leave Epic Online Service in C: Program Files (x86) - Recreate the shortcuts on the launcher's desktop in Epic Games-Launcher-Portal-Binaries-Win64
• Then we can launch the launcher and no more error concerns of EOS-ERR-1603.

For anyone who has this error and has Epic Games Launcher installed on a hard drive that isn't their Windows drive, I fixed the error by installing the launcher onto my Windows drive. That's the only fix I've found so far, it seems to be an issue with EGS not knowing how to install correctly on a non-windows partition.

Another option that seems to work just fine if you happen to already have your Epic Games Launcer installed on another drive other than C:.

Create the Epic Games folder in:

C:\Program Files (x86)

So you path will be C:\Program Files (x86)\Epic Games.

Then run the EpicOnlineServics.msi from

[MY INSTALL LOCATION]\Epic Games\Launcher\Portal\Extras\EOS\EpicOnlineServics.msi

This way you don't have to go through reinstalled the laucher to where you don't want it.

Hi everyone,

thx for all the answers.

So it seems like, that this is a EpicGames and not a Microsoft problem. I have not tested the solutions so far, but installing the Launcher on C isn´t an option for me in any way, so im going to contact the Epic-Support about this and i will reference to this thread so they see, that this is not a windows problem. As soon as i get an answer, i will post it here.

Best regards

WWhat kind of black magic is this? It worked very well for me, thank you friend, in my case, it worked for me today, May 4, 2021.
