UE4 虚幻4无右键菜单.uproject文件无关联解决

TheLudGamer · 发表于 2022-7-29 11:30

在特定情况下，鼠标点击.uproject文件右键菜单消失。

会造成比如：
1。无法手动生成VisualStudioProjectFiles。
2。无法切换UE4各个版本，从而导致版本错开崩溃、每次开启项目自动生成格外副本工程等问题。
搜遍了全网+自己实验，总结解决方法如下：
一、被win10默认防护、其他杀毒软件删除

关闭/卸载杀毒软件、关闭win10防护
以win10防护为例，打开 windows安全中心，
分别关闭病毒和威胁防护、防火墙和网络保护、应用和浏览控制

二、删除注册表，运行CMD

1.删除注册表
1）按下 Ctrl+R 输入 regegit 调出注册表
2）删除 HKEY_CLASSES_ROOT 下的 .uproject文件夹
2.创建cmd并运行重启
新建一个文本文档，然后改名为 UnrealProjectMenuRegistration.cmd，复制如下代码
:: UnrealProjectMenuRegistration.cmd :: :: This batch file will try to find where the Unreal Engine is installed, then update your registry :: to register the Unreal Project File type (and its right click menu for things such as generating :: Visual Studio project files, and launching) :: :: Run as an Administrator, as it&#39;s required for writing to HKLM. :: :: Author: David Moore <david@sadrobot.co.nz> @ECHO OFF echo. echo Locating where Unreal Engine is installed by checking the Windows registry... ::FOR /F &#34;tokens=2*&#34; %%A IN (&#39;reg query &#34;HKLM\SOFTWARE\EpicGames\Unreal Engine&#34; /v &#34;INSTALLDIR&#34;&#39;) DO ( :: SET &#34;UnrealEngineDir=%%B&#34; ::) :: 设置为当前虚幻引擎安装目录 SET UnrealEngineDir=D:\Epic Games\ IF &#34;%UnrealEngineDir%&#34;==&#34;&#34; GOTO CannotFindUnrealEngine echo. echo Using Unreal Engine directory: %UnrealEngineDir% set LauncherPath=%UnrealEngineDir%Launcher\Engine\Binaries\Win64\UnrealVersionSelector.exe echo. echo Adding registry keys for the Unreal Project right click menu... :: HKLM\SOFTWARE\Classes\.uproject reg ADD &#34;HKLM\Software\Classes\.uproject&#34; /ve /d Unreal.ProjectFile /f IF ERRORLEVEL 1 ( echo Couldn&#39;t write to registry.

Can&#39;t find the Unreal Engine. echo. goto TheEnd :TheEnd pause
修改 SET UnrealEngineDir=D:\Epic Games\
修改为Unreal Engine的路径（是UnrealEngine 的路径不是EpicLauncher的）
SET UnrealEngineDir=D:\Epic Games\

保存，右键以管理员身份运行，重启电脑即可。
三、重启后运行UnrealVersionSelector.exe

如，方法一、方法二都失效是使用下述方法：

1.找到Epic Game Lancher的安装目录，在lancher->Engine->Binaries->Win64->UnrealVersionSelector.exe
2.把UnrealVersionSelector.exe 分别拷贝到UE4 不同版本引擎的 Engine->Binaries->Win64目录，例如UE_4.25->Engine->Binaries->Win64
3.双击，以管理员身份运行UnrealVersionSelector.exe，重启电脑即可。
