Not possible to install Epic Games Launcher

[Mitch037]

Describe what you noticed and did

1. Download and launch the installer of Epic Games Launcher
2. While installing the application I get an error message: The Windows Installer Service Could Not Be Accessed
3. The installation process stops and reverts any changes considering the installation failed

According to the official Microsoft support thread, that seems to be related to the issue, it might be caused by the fact that the MSIServer service cannot be started. Indeed, following the suggestion from the Microsoft thread, I tried to launch the service in the box via CMD by net start MSIServer. In response I got an error message: The service did not start due to logon failure.

Tried in both yellow and green box. The installer of Epic Games Launcher outside of Sandboxie works flawlessly.
