Physxloader.dll errors are caused by situations that lead to the removal or corruption of the physxloader DLL file.

This particular DLL file is associated with the PhysX physics engine from NVIDIA, and is normally stored in the program's \NVIDIA Corporation\PhysX\Common\ folder.

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

There are several ways that physxloader.dll error messages might be phrased depending on the cause of the problem. Here are some common physxloader.dll errors:

Physxloader.dll Not Found
This application failed to start because physxloader.dll was not found. Re-installing the application may fix this problem.
Cannot find [PATH]\physxloader.dll
The file physxloader.dll is missing.
This program can't continue because physxloader.dll is missing from your computer
Cannot start [APPLICATION]. A required component is missing: physxloader.dll. Please install [APPLICATION] again.

Physxloader.dll error messages might appear while using or installing certain programs, when Windows starts or shuts down, or maybe even during a Windows installation.

Noting at what point your physxloader.dll error shows up is an important piece of information that will be helpful during troubleshooting.

The physxloader.dll error message could apply to any program or system that might utilize the file on any of Microsoft's operating systems including Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.

How to Fix Physxloader.dll Errors

Do not download physxloader.dll from one of those DLL download sites. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of physxloader.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 physxloader.dll error.

  1. Restore physxloader.dll from the Recycle Bin. The easiest possible cause of a "missing" physxloader.dll file is that you've mistakenly deleted it.

    If you suspect that you've accidentally deleted physxloader.dll but you've already emptied the Recycle Bin, you may be able to recover physxloader.dll with a free file recovery program.

    Recovering a deleted copy of kernelbase.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.

  2. Install the PhysX driver to replace the missing or corrupted physxloader.dll file. Be sure to restart your computer after the driver install.

    If that version of PhysX didn't fix the physxloader DLL error, run the version stored in the game's installation folder (if there is one). That version is sometimes more appropriate for the game than the newer software from NVIDIA's website. Do a search for physx or look in the \redist\ folder in the game's installation directory.

    Try your best to complete this step. Installing this driver is very likely the solution to this DLL error!

  3. Reinstall the program that's making the physxloader.dll error. Most physxloader.dll is missing issues are caused by problems with the Steam engine, and reinstalling it will fix the problem.

    If after the installation, you're still seeing the DLL error, try performing a clean boot and then repairing the Steam game.

  4. Run a virus/malware scan of your entire system. Some physxloader.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file.

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

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

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

  8. Test your memory and then test your hard drive. I'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 physxloader.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 physxloader.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 physxloader.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid physxloader.dll registry entries that might be causing the DLL error.

    I rarely recommend the use of registry cleaners. I've included the option here as a "last resort" attempt before the destructive step coming up next.

  11. 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 physxloader.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 physxloader.dll error using a troubleshooting step prior to this one.

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