found a way to fix DirectX so one can use the original EpicInstaller
- Start Menu → type regedit
- go to
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX - double click Version
- change “Value data” to 4.08.00.0904
- do the same for
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\DirectX
the EpicInstaller should work now, or after a restart
