How to Fix Normaliz.dll Errors

Follow these steps in the order they're listed below to address the more likely fixes first.

Do not download normaliz.dll from a "DLL download" website. There are many reasons why downloading a DLL file that way is a bad idea. If you need a copy of this file, it's best to obtain it from its original, legitimate source.

  1. Restore normaliz.dll from the Recycle Bin. The easiest possible cause of a "missing" normaliz.dll 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 the file with a free file recovery program.

    Start Windows in Safe Mode to complete any of these steps if you're unable to access Windows normally due to the normaliz.dll error.

  2. Run a virus/malware scan of your entire system. Some normaliz.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 normaliz.dll error you're seeing is related to a hostile program that's masquerading as the file.

  3. Use System Restore to undo recent system changes. If you suspect the error was caused by a change made to an important file or configuration, System Restore could solve the problem.

  4. Reinstall the program that uses the normaliz.dll file. If the 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 file, if possible, is a likely solution to this error.

  5. Verify the integrity of the game files if you see the error while playing a game in Steam. You might need to restart your computer afterward.

  6. 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 normaliz.dll file could be included in one of those updates.

  7. Copy the normaliz.dll file from a working computer. Once you have it available on the computer showing the normaliz.dll error, copy it to the system32 folder.

    You can search a working computer for the file with a program like Everything. Copy it to a flash drive to do the transfer.

    It's best to copy the DLL file from a computer that's running the same version of IE. It's possible that using a different normaliz.dll file might not fix the error.

  8. Update the drivers for hardware devices that might be related to normaliz.dll. If, for example, you're receiving a "The file normaliz.dll is missing" error when you play a 3D video game, try updating the drivers for your video card.

    The normaliz.dll file may or may not be related to video cards—this was just an example. The key here is to pay very close attention to the context of the error and troubleshoot accordingly.

  9. Roll back a driver to a previously installed version if normaliz.dll errors began after updating a particular hardware device's driver.

  10. 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 normaliz.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.

  11. Repair your installation of Windows. If the individual troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.

  12. Use a free registry cleaner to repair normaliz.dll related issues in the registry. Although we rarely recommend the use of a registry cleaner program, using one could help by removing invalid normaliz.dll registry entries that might be causing the DLL error.

  13. 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 normaliz.dll error, this should be your next course of action.

    All the information on your hard drive will be erased during this step, so make sure you've made the best attempt possible to fix the normaliz.dll error using a troubleshooting step prior to this one.

  14. Troubleshoot for a hardware problem if any errors persist. After a clean installation of Windows, your DLL problem can only be hardware related.
