..........Uh, I've done all that already; that's the problem.

Are there any logs?

Well there wasn't a crash involved, so......not sure.

Check the logs-folder and add the latest.log

Ok, I see where I've gone wrong in explaining after looking over my prior explanation; I'm trying to install it onto a profile I already have in a different folder.

Is there a reason why you want to install Optifine outside your .minecraft-directory?

Forge or Optifine can be installed at their default location

With your you can still use a different game directory

If it is not working, check for a custom Launcher like AT Launcher - the game directory it there were you run this Launcher

With it, you can search for a clean Forge or Optifine modpack

Because I used to be able to use it in a different folder, just like any other mod? I've used Optifine before on previous versions, and I did not have to go through all of this iirc. Which is why I'm really confused, here.

If you load Optifine with Forge then you can run Optifine.jar in a new location

Install Forge at its default location

In your profile select the forge version and the path to your new location

After running this forge version at the new location will be a mods folder created

There you can put Optifine in

Forge IS installed in the default location though. I can't install Optifine directly into the other folder, and I can't get the folder to accept the .jar copied from the default folder either.

any change of updated forge support for 1.12.2? I could really use this mod.

There are 1.12.2 versions of it:

https://optifine.net/downloads

But not for the forge version I'm on. It's only 2847 I'm on 2854

You can use the latest version anyway - the given Forge version is a recommendation.

For 1.12.2 you also can ignore that - it is important for the newer Optifine versions

Please Help! I followed the instructions and have downloaded optifine but it wont let me add shaders!! What am I doing wrong??

After installing Optifine make sure you select the Optifine profile at Installations

After running Optifine once then you will find a shaderpacks folder in your .minecraft-folder

Download some shaderpacks:

https://www.curseforge.com/minecraft/customization/search?search=Shaders

and put the zip file into your shaderpacks-folder

Ingame at video setting you will find "shaders" - there you can choose the downloaded shaders

OptiFine 1.16.5_HD_U_G7 still has invisible mobs :c

Here during the 10th anniversary of this mod!

I've downloaded and installed every single version of Optifine for 1.12.2 Forge. Each one of them crashed upon boot. I imagine the log would be too large to fit in a standard pastebin, and I wouldn't even know where to find the exact logs. I really would want this in my modded Minecraft because I know it would fit visually. Please advise.

Use the latest.log from /.minecraft/logs/

and add it with paste.ubuntu.com

Hi there,

pretty easy install. Used a fresh Minecraft install 1.16.5 and started it once (for the downloads). Executed the Optifine installer successfully. When I run the launcher, I can start Optifine version of minecraft - but ... it looks exactly the same as the unmodified game. I don't see any difference. Do I have to activate it somehow? No idea what's wrong here :-(
