In some cases, msxml3.dll errors could indicate a registry problem, a virus or malware issue, or even a hardware failure. There are several different ways that msxml3.dll errors can show up on your computer. Here are some of the more common ways that you might see msxml3.dll errors: Msxml3.dll Not FoundThis application failed to start because msxml3.dll was not found. Re-installing the application may fix this problem.Cannot find [PATH]\msxml3.dllThe file msxml3.dll is missing.Cannot start [APPLICATION]. A required component is missing: msxml3.dll. Please install [APPLICATION] again. Msxml3.dll error messages might appear while using or installing certain programs, when Windows starts or shuts down, or maybe even during a Windows installation. The context of the msxml3.dll error is an important piece of information that will be helpful while solving the problem. The msxml3.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 Msxml3.dll Errors Do not download msxml3.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 msxml3.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 msxml3.dll error. Restore msxml3.dll from the Recycle Bin. The easiest possible cause of a "missing" msxml3.dll file is that you've mistakenly deleted it. If you suspect that you've accidentally deleted msxml3.dll but you've already emptied the Recycle Bin, you may be able to recover msxml3.dll with a free file recovery program. Recovering a deleted copy of msxml3.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. Download and install MSXML 3.0 from Microsoft. This is the official source of the msxml3.dll file and will replace a missing msxml3.dll file, hopefully fixing any related DLL errors. There are actually several versions of Microsoft XML parser (MSXML), but v3.0 is the only one that provides the msxml3.dll file. Other versions can be used to get similar DLL files. MSXML 6.0, for example, is the one that you need if you're getting msxml6.dll error messages. Try your best to complete this step. Installing the program that provides the msxml3.dll file, if possible, is a likely solution to this DLL error. Reinstall the program that uses the msxml3.dll file. If the msxml3.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file. Completing Step 2 to install MSXML 3.0 should be enough to fix the msxml3.dll error, but it's possible that the program you're using needs the DLL file to be in a folder different from where MSXML puts it. A reinstall should accomplish what you need. Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the msxml3.dll file. Since this DLL file is provided by Microsoft, the System File Checker tool might restore it. Run a virus/malware scan of your entire system. Some msxml3.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 msxml3.dll error you're seeing is related to a hostile program that's masquerading as the file. Use System Restore to undo recent system changes. If you suspect that the msxml3.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem. Update the drivers for hardware devices that might be related to msxml3.dll. If, for example, you're receiving a "The file msxml3.dll is missing" error when you play a 3D video game, try updating the drivers for your video card. The msxml3.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. Roll back a driver to a previously installed version if msxml3.dll errors began after updating a particular hardware device's driver. 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 msxml3.dll file could be included in one of those updates. 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 msxml3.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 msxml3.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 msxml3.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid msxml3.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. 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 msxml3.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 msxml3.dll error using a troubleshooting step prior to this one. Troubleshoot for a hardware problem if any msxml3.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related. Need More Help?
