How to Fix Zlib1.dll Errors
Follow these steps in the order they’re presented, which is by difficulty level.
Restore zlib1. dll from the Recycle Bin. The easiest possible cause of a “missing” file is that you’ve mistakenly deleted it. If you suspect this, but you’ve already emptied the Recycle Bin, you may be able to recover it with a free file recovery program. Just make sure it was you that deleted it (not your antivirus program), and that it was working fine when you did that. Start Windows in Safe Mode to complete any of these steps if you’re unable to access Windows normally due to the error. Run a virus/malware scan of your entire system. Some zlib1. 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 error you’re seeing is related to a hostile program that’s masquerading as the file. Reinstall the program that uses the zlib1. dll file. If the 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 this file, if possible, is a likely solution to this DLL error. Install MinGW and copy the zlib1. dll file to where you need it. Follow this step if you’re not having luck getting the zlib1. dll file from reinstalling the program that uses it. Some other similar solutions can be found in this Stack Overflow thread. Use System Restore to undo recent system changes. If you suspect that the error was caused by a change made to an important file or configuration, System Restore could solve the problem. Update the drivers for hardware devices that might be related to zlib1. dll. If, for example, you’re receiving a “The file zlib1. dll is missing” error when you play a 3D video game, try updating the drivers for your video card. The zlib1. dll file may or may not be related to video cards or multimedia programs—this was just an example. The key here is to pay very close attention to the context of the error and troubleshoot accordingly. Roll back a driver to a previously installed version if the errors began after updating a particular hardware device’s driver. 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 zlib1. 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 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 zlib1. dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid zlib1. 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. This will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the zlib1. dll error, this should be your next course of action. After this step, you’ll likely need to repeat step 4 to get the program that supplies the zlib1. dll file. 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 error using a troubleshooting step prior to this one. Troubleshoot for a hardware problem if any zlib1. dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.
