Hi guys, today I'm going to teach you how to install Optifine for minecraft 1.7.4 or 1.7.5.

First, you need to click [url=(Ad link removed)/adloadx.php?f=OptiFine_1.7.5_HD_U_D1.jar]here.[/url] That link will bring you to the download for 1.7.5. The link for 1.7.4 is [url=(Ad link removed)/adloadx.php?f=OptiFine_1.7.4_HD_U_D1.jar]here.[/url] When you're on whatever page, you click the blue text. Don't click on any of the ads. When you download it, and if you use chrome, it will ask you if you want to keep the file. Click "keep". When the file is downloaded, drag it onto your desktop.

When it's on your desktop, double click it. A window will open. It will ask you if you want to install optifine. Click install. A new window will pop up saying that optifine has been installed. Now you need to open your minecraft launcher. Go into your profile editor. There will be a profle called "optifine", or something similar. Right click it and delete it. 

Now go back to the main screen of the launcher. Select the profile you play with the most, provided it isn't already selected. Click the "edit profile" button. A new window will pop up. Go down to where it says "use version". Click the box that says what version you're using. Look for a version that says "Release 1.7.5-OptiFine_HD_U_D1". For 1.7.4 it will be something similar. Click the "save profile" button on the bottom. Now click the "Play" button.

You have now installed OptiFine.
