Hi @bnhrsch !
Since you followed the troubleshooting guide, here are some other things you can try.
- Make sure to run the installer as administrator and check if you have fully permissions on the installed folder.
- Check your windows update
- Disable antivirus/Firewall for the installation
- Install both versions of Microsoft Visual C++ x86 and x64
- Try installing on a clean different location.
- If nothing works out re-install Epic Games launcher
Hope it helps
