However, the fm20.dll error message might apply to any other 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 Fm20.dll Errors Do not download fm20.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 fm20.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 fm20.dll error. Restore fm20.dll from the Recycle Bin. The easiest possible cause of a "missing" fm20.dll file is that you've mistakenly deleted it. If you suspect that you've accidentally deleted fm20.dll but you've already emptied the Recycle Bin, you may be able to recover fm20.dll with a free file recovery program.

The fm20.dll file is most likely associated with a Microsoft Office program, so reinstalling MS Office should be your primary focus in this step. Don't forget to save your product key first. Try your best to complete this step. Reinstalling the program that provides the fm20.dll file, if possible, is a likely solution to this DLL error. Run the sfc/scannow System File Checker command to replace a missing or corrupt copy of the fm20.dll file. Because this DLL file is provided by Microsoft, the System File Checker tool should restore it. 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 fm20.dll file might be included in one of those updates. Run a virus/malware scan of your entire system. Some fm20.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 fm20.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 fm20.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 fm20.dll. If, for example, you're receiving a "The file fm20.dll is missing" error when you play a 3D video game, try updating the drivers for your video card. The fm20.dll file is most likely not 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 fm20.dll 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 fm20.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 fm20.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 fm20.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid fm20.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. 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 fm20.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 fm20.dll error using a troubleshooting step prior to this one. Troubleshoot for a hardware problem if any fm20.dll errors persist.
