My Launcher apparantly cannot install EOS
Epic Games Launcher is unable to complete EOS installation.
The EOS MSI fails with error 1603 during the InitializeComponents custom action. Investigation of the MSI logs shows that EpicOnlineServicesUserHelper.exe is launched by the installer but times out and is terminated.
Further debugging shows:
Manual execution of:
EpicOnlineServicesUserHelper.exe --setup --msimode=NewInstall
completes successfully and exits with code 0.
The EpicOnlineServices Windows service is created successfully.
Starting the service causes EpicOnlineServicesHost.exe to launch EpicOnlineServicesUserHelper.exe as the updater process.
The updater immediately exits with service exit code 77.
The updater log contains the error:
“LogUpdaterService: Error: No updater mode specified”
Windows version: 10.0.19045
EOS version: 5.3.0
Launcher repeatedly attempts EOS installation because the service never starts successfully.
Ive already gone down the provided help list for this error and none of that worked. I dont want any suggestions regarding reinstalling the Launcher or going to Microsoft support. There is nothing wrong with my MSI service as other MSI installers worked just fine. THe problem lies withing the EOS executables.
I cannot properly use the engine anymore for my job. Is there some way to disable EOS entirely so I can work.
