How to fix GLFW error 65543/65542 in Minecraft
This error often occurs for owners of new hardware or after reinstalling Windows. Below are the main methods to resolve the issue. They are presented as logical steps that follow one another. If the previous method doesn't help, you should move on to the next one.
Method 1: Installing New Java
One of the possible solutions to the problem. You should go to the official Java website (https://www.oracle.com/java/technologies/downloads/). There, you need to download the latest available version. The main thing is that it should be at least Java 16, as this is the version supported by the game starting from 1.17. Download the file and follow the installer's instructions. Done! The new Java is installed.
Method 2: Manually Adding OpenGL.dll File
Usually, there are no problems when installing Java files, as the installer automatically installs opengl32.dll or opengl64.dll. However, in Windows 10, Java installers often skip this step in the installation process. It is the absence of this file in the Java directory that causes the error.
Step 1: Go to the website https://ru.dll-files.com/opengl32.dll.html. Download the file suitable for your operating system's architecture (64-bit or 32-bit). To find out which architecture is used on your computer, right-click on "My Computer" on the desktop, select properties. The "System type" will be displayed there. Download a file with the same architecture as your OS.
Step 2: Locate the "bin" folder in Java\JRE\bin. If Java is installed by default, the path will be as follows:
"C:\Program files\Java\jre\bin\"
Copy the opengl64.dll (or opengl32.dll) file into the "bin" directory. If prompted to provide administrator access, agree.
Step 3: Launch Minecraft again. If the problem persists, then proceed to the next method.
Method 3: Removing DisplayLink (selectively)
The DisplayLink driver (if you are using it) sometimes conflicts with certain Java files. However, it can be safely removed.
Step 1: Go to "Programs and Features". You can access it through the "Start" menu, "Control Panel," and find the appropriate icon there. Alternatively, you can press "Win + R" and enter appwiz.cpl in the "Run" window.
Step 2: Find DisplayLink Graphics Driver in the list. Remove it.
Step 3: After the removal is complete, restart your computer. Open Minecraft and check if the issue has been resolved.
Method 4: Reinstalling Video Card Drivers
The problem may lie with outdated drivers for your device. They may simply not understand how to interact with OpenGL.
Step 1: Press "Win + R". The "Run" window appears. Enter devmgmt.msc and go to "Device Manager."
Step 2: Find "Display adapters" or "Video adapters." Remove all the drivers from there. WARNING! The screen may become dim, flicker, or glitch. These are all normal phenomena as the system returns to its default drivers.
Step 3: Next, go to "Programs and Features." To do this, select this file in the Start menu > Control Panel. Or press "Win + R" and enter appwiz.cpl, as in the previous method.
Step 4: Important note: everyone has different hardware, including graphics cards. Therefore, you need to independently find components of specific equipment. Usually, these are Nvidia, AMD, or Intel graphics cards. The last two are integrated. On certain computers, there may be both integrated and discrete graphics cards. There are also USB graphics cards, but they are not used for games.
Therefore, you need to find + delete ALL files related to the GPU (graphics card). It is important not to touch other components and utilities.
Step 5: Restart your computer. After the restart, go to the hardware manufacturer's website and download new drivers for your graphics card. For example, links to the websites of the three mentioned companies are provided below.
Nvidia: https://www.nvidia.com/Downloa...
Intel: https://www.intel.com/content/...
AMD: https://www.amd.com/en/support
Step 6: Install the drivers for your graphics card. Restart your computer. Open Minecraft again and check.
Method 5: Hardware Replacement
If all the subsequent methods have been followed correctly and have not produced any results, then the graphics card should be replaced. Most likely, the hardware is outdated and does not support the new version of Minecraft. However, this method does not apply to those who had the game working fine before reinstalling the system.
Nevertheless, it is worth double-checking the correctness of the previous methods. Especially if the GLFW error 65543/65542 has not disappeared. Additionally, you can change the game launcher as the problem may sometimes be hidden in it. In any case, the problem can be resolved. The main thing is to find the root cause: drivers, hardware, or the absence of the opengl.dll file.
