Some Minecraft players end up encountering the GLFW Error 65542 every time they attempt to launch the game. This problem is mostly reported to occur on Windows 10 with the Java-based version of Minecraft.
The majority of users that have been struggling with this error code were able to fix the GLFW Error 65542 by copying the missing opengl32.dll file manually into the JRE (Java directory). If that doesn’t work or you want to avoid doing any manual modifications to the JAVA directory, you can also reinstall every GPU driver in order to ensure that the opengl32.dll file gets reinstalled.
However, if you’re encountering this issue with the Java version of Minecraft, this problem can also be facilitated by a conflict with a DisplayLink driver. In this case, you can fix the issue by uninstalling the conflicting driver and re-launching the game.
Method 1: Adding the OpenGL.DLL Manually
Even though every Dynamic Link Library file that is required is typically included by your GPU driver, that’s not always the case. Even more, you might have deleted opengl32.dll or opengl64.dll by mistake, which will end up triggering the GLFW Error 65542.
If this scenario is applicable, one way to fix the problem is to manually copy the missing .DLL file to the Java and JRE folder in order to allow Minecraft to make use of OpenGL. This fix was confirmed to work by a lot of users that are currently encountering the 65542 Error on Minecraft.
To add the OpenGL.dll file manually to the Java path, follow the instructions below:
- Open this link (here) and download the Minecraft_OpenGL.zip file and wait for the download to complete. Once the download is finished, extract the contents of the archive with a utility like 7zip or WinZip.
- Once the contents of this utility have been extracted, copy the file that’s compatible with your OS architecture on your clipboard by right-clicking on it and choosing Copy or Cut.
Note: If you don’t know which OS architecture you’re using, right-click on My Computer (This PC) and choose Properties from the context menu. Inside the Properties screen, check the listing under System type – that’s your OS architecture.
- Next, navigate to the following location and paste the opengl32.dll file that you previously copied on your clipboard:
C:\Program Files\Java\*JRE Version*\bin
Note: Keep in mind that *JRE Version* is simply a placeholder. You will need to replace it with your JRE version. Also, if you installed the Java environment in a custom location, navigate there instead.
- When you’re prompted by the UAC (User Account Control), click Yes to grant admin access.
- Once the opengl32.dll file has been copied in the correct environment, launch Minecraft once again and see if the problem is now fixed.

Method 2: Uninstalling DisplayLink (if applicable)
If you’re actively using a DisplayLink driver, keep in mind that this technology has the potential of conflicting with the Java-powered version of Minecraft. Some users that we’re encountering the GLFW Error 65542 issue whenever they attempted to launch Minecraft have confirmed that he issue went away for good as soon as they ended up uninstalling DisplayLink USB Graphics Software.
If this scenario is applicable to you, follow the instructions below to uninstall the DisplayLink USB Graphics Software from your computer in order to eliminate the conflict with Minecraft:
- Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ and press Enter to open up the Programs and Features menu.
- Once you’re inside the Programs and Files menu, scroll down through the list of installed applications and locate the entry named DisplayLink Graphics Driver.
- When you manage to locate it, right-click on it and choose Uninstall from the context menu to initiate the uninstallation process.
- At the confirmation prompt, click Yes, then follow the on-screen instructions to complete the uninstallation process.
- After the operation is complete, restart your computer and launch Minecraft again once the next startup is complete to see if the conflict has been eliminated.
In case this scenario was not applicable or you already performed this with no success, move to the next potential fix below.
Method 3: Reinstalling Video Card Drivers
As it turns out, you will also encounter the GLFW Error 65542 error if you’re using a selection of outdated graphics drivers that don’t know how to work with the OpenGL version that Minecraft uses. However, if you had malware issues recently, this problem might also by a security scan if the operation ended up quarantining some files that are required to run OpenGL.
If you haven’t updated your GPU drivers in a while, it’s likely that you will be able to fix the issue by using Device Manager and Programs and Features to uninstall anything related to your GPU and then reinstall them from the official channels.
In the event you’re not exactly sure on how to do this, follow the instructions below:
- Press Windows key + R to open up a Run dialog box. Next, type ‘devmgmt.msc’ and press Enter to open up Device Manager. If you are prompted by the UAC, click on Yes to grant admin access.
- Once you’re inside Device Manager, expand the drop-down menu associated with Display adapters, then go ahead and uninstall every graphics driver by right-clicking on them and clicking on Uninstall – Do this for every entry inside Device Adapters. If you have both an integrated and a dedicated GPU, uninstall both types of drivers.
Note: Your screen might flicker after you do the uninstallation. This happens because your OS will revert back to the generic drivers.
- Once every GPU driver has been uninstalled from Device Manager, close the Device Manager utility.
- Press Windows key + R once again to open up another Run dialog box. Next, type ‘appwiz.cpl’ and press Enter to open up the Programs and Features screen.
- Once you’re inside the Programs and Features menu, scroll down through the list of installed applications an begin to uninstall anything related to your GPU manufacturer (Nvidia AMD or Intel). You can ensure that you’re not leaving anything behind by clicking the Publisher column in order to order them one after the other. Just right-click on every GPU related tool or driver and then click Uninstall from the context menu.
- Inside the uninstallation screen, follow the on-screen instructions to complete the process. After every relevant driver is uninstalled, reboot your computer and wait for the next startup to complete.
- After the next startup is complete, visit the download page associated with you GPU manufacturer and download the latest driver version that’s available for your particular GPU model:
Nvidia’s Download Page
AMD’s Download Page
Intel Graphics Download Page
- Download and install the recommended drivers based on your graphics card model, then reboot your computer and launch Minecraft once the next startup is complete to see if the problem is fixed.
