在你电脑中找到UnrealVersionSelector通常和epiclauncher是同一个根目录
epiclauncher路径是:D:\MyEpic\Epic Games\Launcher\Portal\Binaries\Win32\EpicGamesLauncher.exe

UnrealVersionSelector.exe`的路径是:D:\\MyEpic\\Epic Games\\Launcher\\Engine\\Binaries\\Win64\\UnrealVersionSelector.exe
因此最简单的方法 就是只加一个菜单 下面是注册表的方法直接添加

Windows Registry Editor Version 5.00[HKEY_CLASSES_ROOT\*\shell\run]@="Launch game""Icon"="\"D:\\MyEpic\\Epic Games\\Launcher\\Engine\\Binaries\\Win64\\UnrealVersionSelector.exe\""[HKEY_CLASSES_ROOT\*\shell\run\command]@="\"D:\\MyEpic\\Epic Games\\Launcher\\Engine\\Binaries\\Win64\\UnrealVersionSelector.exe\" /game \"%1\""

但是此方法只有一个,
就是右键菜单多了一个launcher game
如下

启动后提示这个

那么如何修复增加switch unreal engine version等呢

直接打开D:\MyEpic\Epic Games\Launcher\Portal\Binaries\Win32\EpicGamesLauncher.exe即可,
提示这个 点击 修复 fix now就行

可以考虑把\EpicGamesLauncher.exe复制一份到ue5.1 或者5.2等路径打开 如D:\MyEpic\Epic Games\UE_5.2\Engine\Binaries\Win64\UnrealEngineLauncher.exe
再尝试打开之前的,发现可以打开了

高级方案
下面是直接用注册表生成切换版本 生成visual studio文件 以及打开的注册表

Windows Registry Editor Version 5.00

以及
