4 Ways to Fix OptiFine Installer Not Working Issue [Partition Manager]

Last Updated November 10, 2022
If you are playing Minecraft, you may want to install OptiFine mod, which can improve Minecraft performance. However, some people report that they have encountered OptiFine installer not working issue. In this post, MiniTool Partition Wizard offers 4 ways to fix the OptiFine not installing problem.
OptiFine is one of the most downloaded Minecraft mods ever made. It not only helps you run Minecraft fast with no lag, but also can increase the graphics of Minecraft, making it look absolutely beautiful.
However, some people may encounter OptiFine not installing issue. The possible causes of this issue include:
- The downloaded OptiFine file is incorrect or you didn’t unzip the file.
- The OptiFine installation process is wrong.
- A special file opening method is required.
- The .jar association has been hijacked.
To solve the OptiFine installer not working issue, you can refer to the following methods.
Fix 1. Download Correct OptiFine
Please download the OptiFine file from optifine.net. The OptiFine file from this website should be safer and more reliable than files you download from other sites. In addition, the OptiFine file should be a .jar file. If your downloaded file is a .rar file, you should unzip it first.
Fix 2. Perform Correct OptiFine Installation Process
To install OptiFine smoothly, please make sure you have completed the following steps:
- Make sure you have Java installed.
- Please install the most recent version of Minecraft.
- Before installing OptiFine, make sure you have launched the version of Minecraft you want to install OptiFine for at least once from the Minecraft Launcher.
- Make sure that the Minecraft Launcher is closed before installing OptiFine.
- Double-click the OptiFine .jar file. It will open OptiFine Installer. Click Install to start the installation process.
Fix 3. Try Other File Opening Methods
If you have tried the above methods, but OptiFine won’t open still. You can try using other methods to open the OptiFine Installer file, for example:
- Right-click the OptiFine file and choose Open with > Java (TM) Platform SE binary.
- Some people also suggest you try using command to run the OptiFine Installer file. Press Windows key + R, type «cmd» in that box, type «cd + filepath» to open the folder where the OptiFine is stored, and then type «java -jar [name of Optifine file, replacing any spaces with underscores].jar» to run the .jar file.
Fix 4. Fix Hijacked .jar Association
In most cases, the OptiFine installer not working issue is caused by hijacked .jar association. In general, .jar files will be assigned to javaw.exe, which is the right program to execute a .jar file. However, some programs, especially many zip/unzip programs, will steal .jar file type, because a jar is stored in the .zip format.
To solve this problem, you can use the following 2 ways:
- Reinstall Java. Please uninstall Java. Then, download the latest Java version and install it. This will fix some bugs.
- Use jarfix.exe program. This program can help you restore the .jar association with javaw.exe easily. Please open https://johann.loefflmann.net/en/software/jarfix/index.html. Then, follow the guide to download and use the jarfix.exe program.

Установщик Minecraft Optifine не работает (3 способа исправить) (01.30.23)
Установщик optifine 
не работает minecraft
Minecraft предлагает всем своим игрокам множество возможностей доступа и настроек. Игроки, которые играют в Minecraft на компьютере, могут легко использовать моды и шейдеры, чтобы значительно улучшить свой опыт. Сообщество модов Minecraft — одно из самых активных сообществ разработчиков модов. Для игры доступны буквально миллионы модов, и каждый из них по-своему полезен и интересен. Один из наиболее популярных модов, доступных для игры, — это Optifine.
Что такое Optifine?
Популярные уроки Minecraft
Optifine — один из множества различных модов, доступных для Minecraft. Это позволяет пользователям значительно улучшить визуальные эффекты и производительность игры. Optifine значительно увеличивает количество кадров в секунду, отображаемых на экране игрока во время игры в Minecraft. Optifine — это файл jar, что означает, что он был специально разработан для работы с Java. Сам Minecraft также был написан на Java и использует его для работы на компьютерах.
Optifine абсолютно бесплатен и является отличным дополнением к игре Minecraft для любого игрока. Как уже упоминалось, это значительно улучшает опыт игрока в Minecraft. Его легко загрузить и работать с ним, если игроки не столкнутся с проблемой.
Установщик Minecraft Mod Optifine не работает: как исправить?
Однако, как написано выше, довольно легко загрузить и установить Optifine на свой компьютер. , иногда при этом вы можете столкнуться с проблемой. Эта проблема остановит работу установщика мода. Это в конечном итоге остановит вас от установки Optifine. Попробуйте эти исправления, если вы столкнулись с этой проблемой.
У большинства игроков, играющих в Minecraft, Java не установлена на компьютере полностью. Эти игроки используют встроенную версию Java, доступную в Minecraft. Эта встроенная версия Java запускается, когда игроки запускают Minecraft, а затем закрывается, когда игроки закрывают игру.
Это очень проблематично, поскольку ваш компьютер не будет знать, что делать с файлом jar без помощи Java . Все, что вам нужно сделать, чтобы решить эту проблему, — это установить Java на ваше устройство. Перейдите на официальный сайт Java, чтобы загрузить его бесплатно.
Помимо загрузки Java, вы также должны убедиться, что она обновлена. Устаревшие версии Java вызывают множество проблем с Optifine, поэтому вам необходимо быстро обновить его. Как и в случае с последним исправлением, вам нужно будет перейти на официальный сайт Java. Затем сайт позволит вам загрузить последнее обновление Java.
Возможно, ваше антивирусное программное обеспечение идентифицировал Optifine как угрозу. В этом случае вы не сможете использовать мод. Просто проверьте свой антивирус, чтобы убедиться, так ли это. Вам нужно будет предоставить Optifine доступ, если антивирус заблокировал его с вашего устройства. Разблокировать мод — это все, что вам нужно сделать, чтобы программа установки Optifine снова начала правильно работать.

I’ve figured out how to load Minecraft with Optifine OR other mods (by changing between the options in the dropdown menu on Forge). And I’ve heard that you’re supposed to be able to just drag and drop the Optifine file into the «mods» folder to include it with the other mods. But when I load the game it keeps telling me «Optifine is not a valid mod file». Please help!

Make sure to use the .jar file option for Optifine. Copy and paste the file into the mods folder.
BTW: why did you make a new post?

Well it’s a different problem now, technically. But yeah, it’s an executable .jar file and everything. When I put it in the mods folder, it just keeps saying Optifine isn’t a valid mod file

1.If you are using 1.14.4+ versions of Minecraft you need OptiForge or OptiFabric (for whichever modloader, you can get them on Curseforge) alongside OptiFine to make it work (no need to extract it at all).
2.For 1.12.2 and before it should work fine extracted (so as OptiFineMod.jar)
3.The OptiFine jar on it’s own that can be double clicked is for extracting it as a mod or installing an OptiFine Vanilla profile, and has no relevance to mods.
Hopefully that helps.

Apologies, I am just now seeing this. I managed to get Optifine working without installing OptiForge. I was following the instruction (I’ve seen in a few tutorials) to click «Install» when clicking «Extract» was the way to go. Is there still any benefit in installing OptiForge, or should I leave it alone now?
