Fix: Error 2203 when installing Epic Games Launcher

When installing Epic Games Launcher, you may get the following error code:

The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2203.

Cause

This error code occurs if the current user does not have permission to install the program in the folder path or if the Temp folder permissions are incorrect.

When you run one of these commands, it may show an “Access is denied” error or the required ACEs may be missing.

icacls c:\windows\temp

icacls "%temp%"

icacls "%appdata%"

The “administrators” group and the SYSTEM account need Full Control permissions for the Temp folders.

Resolution

To resolve the Epic Games Launcher error code 2203, follow the steps below.

Launch the installer from admin Command Prompt

Open an admin Command Prompt window and start the Epic installer manually, using msiexec.exe:

For example:

msiexec.exe /i "C:\EpicInstaller-17.2.0.msi"

Fix the Temp folder permissions

Fix the Temp folder permissions. To do so, open admin Command Prompt and run the following commands:

takeown /f c:\windows\temp /a

icacls c:\windows\temp /reset

icacls c:\windows\temp /inheritance:r

icacls c:\windows\temp /grant *S-1-5-32-544:(OI)(CI)(F)

icacls c:\windows\temp /grant *S-1-5-18:(OI)(CI)(F)

icacls c:\windows\temp /grant "%username%":(OI)(CI)(F)

Next, fix the user’s temp folder permissions using these commands:

takeown /f "%temp%"

icacls "%temp%" /reset

icacls "%temp%" /inheritance:r

icacls "%temp%" /grant *S-1-5-32-544:(OI)(CI)(F)

icacls "%temp%" /grant *S-1-5-18:(OI)(CI)(F)

icacls "%temp%" /grant "%username%":(OI)(CI)(F)

md "%temp%\Low"

icacls "%temp%\Low" /setintegritylevel (OI)(CI)low

The above should fix the permissions for the c:\windows\temp and the %temp% folders.
