How to Fix Opengl32.dll Errors Do not download opengl32.dll from a "DLL download" website. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of opengl32.dll, it's best to obtain it from its original, legitimate source. Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the opengl32.dll error. Restore opengl32.dll from the Recycle Bin. The easiest possible cause of a "missing" opengl32.dll file is that you've mistakenly deleted it. If you suspect that you've accidentally deleted opengl32.dll but you've already emptied the Recycle Bin, you may be able to recover opengl32.dll with a free file recovery program. Recovering a deleted copy of opengl32.dll with a file recovery program is a smart idea only if you're confident you've deleted the file yourself and that it was working properly before you did that. Reinstall the program that uses the opengl32.dll file. If the opengl32.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file. Try your best to complete this step. Reinstalling the program that provides the opengl32.dll file, if possible, is a likely solution to this DLL error. Update the drivers for hardware devices that might be related to opengl32.dll. If, for example, you're receiving a "The file opengl32.dll is missing" error when you play a 3D video game, try updating the drivers for your video card. Roll back a driver to a previously installed version if opengl32.dll errors began after updating a particular hardware device's driver. Run a virus/malware scan of your entire system. Some opengl32.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file. It's even possible that the opengl32.dll error you're seeing is related to a hostile program that's masquerading as the file. Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The opengl32.dll file could be included in one of those updates. Use System Restore to undo recent system changes. If you suspect that the opengl32.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem. Test your memory and then test your hard drive. We've left the majority of hardware troubleshooting to the last step, but your computer's memory and hard drive are easy to test and are the most likely components that might cause opengl32.dll errors as they fail. If the hardware fails any of your tests, replace the memory or replace the hard drive as soon as possible. Repair your installation of Windows. If the individual opengl32.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions. Use a free registry cleaner to repair opengl32.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid opengl32.dll registry entries that might be causing the DLL error. We rarely recommend the use of registry cleaners. We've included the option here as a "last resort" attempt before the destructive step coming up next. Perform a clean installation of Windows. A clean install of Windows will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the opengl32.dll error, this should be your next course of action. All the information on your hard drive will be erased during a clean install. Make sure you've made the best attempt possible to fix the opengl32.dll error using a troubleshooting step prior to this one. Troubleshoot for a hardware problem if any opengl32.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.
