How to Fix Eax.dll Not Found or Missing Errors

Eax.dll errors are caused by situations that lead to the removal or corruption of eax.dll, a DLL file associated with EAX Unified from Creative Labs.

In some cases, eax.dll errors could indicate a registry problem, a virus or malware issue, or even a hardware failure.

Eax.dll Errors

There are several ways eax.dll errors can show up on your computer. Here are some of the more common error messages you might see:

• Eax.dll Not Found
• This application failed to start because eax.dll was not found. Re-installing the application may fix this problem
• Cannot find [PATH]\eax.dll
• The file eax.dll is missing
• Cannot start [APPLICATION]. A required component is missing: eax.dll. Please install [APPLICATION] again

These errors might appear while using or installing certain programs or video games, or when Windows starts or shuts down.

The context of the eax.dll error is an important piece of information that will be helpful while solving the problem.

How to Fix Eax.dll Errors

Follow these steps in the order they're given below to try the simpler solutions first.

1. Restore eax.dll from the Recycle Bin. The easiest possible cause of a "missing" eax.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 data recovery program.

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

2. Install EAX4 Unified Redist (use the Windows executable link on the download page).

   This should download the eax.dll file to your computer, after which you can copy the DLL file to wherever the error messages say it's missing.

3. Update the drivers for hardware devices that might be related to eax.dll. If, for example, you're receiving a "The file eax.dll is missing" error when you try to use software that relies on your sound card, try updating those drivers.

   The Creative Worldwide Support page provides links to drivers for Creative Labs sound cards, but free driver updater tools provide a much easier way to get the right drivers you need.

4. Reinstall the program that uses the eax.dll file. If the eax.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file.

5. 
   Run a virus/malware scan of your entire system. Some eax.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 eax.dll error you're seeing is related to a hostile program that's masquerading as the file.

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

7. 
   Roll back a driver to a previously installed version if eax.dll errors began after updating a particular hardware device's driver.

8. 
   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 eax.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.

9. 
   Repair your installation of Windows. If the individual eax.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.

10. 
    Use a free registry cleaner to repair eax.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid eax.dll registry entries that might be causing the DLL error.

    We rarely recommend the use of registry cleaners (see why in our Registry Cleaners FAQ). They're included here as a "last resort" attempt before the destructive step coming up next.

11. 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 eax.dll error, this should be your next course of action.

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

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