Luxor 1, Amun Rising and Luxor 2 for Steam use encryption in the launcher to be able to launch the game, Windows 8 and later has broken the functions used.
This mod is a set of replacement launchers for Luxor, Luxor 2 and Luxor Amun Rising so that they can still be played on modern systems.

Luxor 2 has an extra patch that is applied by the replacement launcher automatically, since that game has a broken minimum Windows version check.

This mod should work for every version of the game except Luxor 2, where the broken Windows version check won't be fixed on anything that doesn't use the same platform.dll as the Steam version.

Installation

Download luxor-launchers.zip and replace the exe in the game folder of the version you want to play.
