In some cases, msstdfmt.dll errors could indicate a registry problem, a virus or malware issue, or even a hardware failure. The msstdfmt.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. Msstdfmt.dll Errors There are several different ways that msstdfmt.dll errors can show up on your computer. Here are some of the more common ways that you might see msstdfmt.dll errors: Msstdfmt.dll Not FoundThis application failed to start because msstdfmt.dll was not found.

The context of the msstdfmt.dll error is an important piece of information that will be helpful while solving the problem. How to Fix Msstdfmt.dll Errors Don't download msstdfmt.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 msstdfmt.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 msstdfmt.dll error. Restore msstdfmt.dll from the Recycle Bin. The easiest possible cause of a "missing" msstdfmt.dll file is that you've mistakenly deleted it. If you suspect that you've accidentally deleted msstdfmt.dll but you've already emptied the Recycle Bin, you may be able to recover msstdfmt.dll with a free file recovery program. Recovering a deleted copy of msstdfmt.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. Run a virus/malware scan of your entire system. Some msstdfmt.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 msstdfmt.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 msstdfmt.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem. Reinstall the application that uses the msstdfmt.dll file. If the msstdfmt.dll 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 msstdfmt.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 msstdfmt.dll file. If 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 msstdfmt.dll file could be included in one of those updates. Copy the msstdfmt.dll file from a working computer. You can then paste the file in the appropriate folder to hopefully stop the DLL error. The original location for the msstdfmt.dll file is C:\Windows\system32\ on a 32-bit version of Windows, and C:\Windows\SysWOW64\ for a 64-bit version. Copy and paste the msstdfmt.dll file from and to the same folder that corresponds with your version of Windows. See How To Tell if You Have Windows 64-bit or 32-bit if you need help knowing which file to copy and which folder to copy it to. After the DLL file has been pasted to the right folder on your computer, you must register the DLL file with Windows Registry. You can do this using the regsvr32 command in a Command Prompt with administrative privileges; just use whichever command applies to your version of Windows: For 32-bit versions: regsvr32 c:\windows\system32\msstdfmt.dll 64-bit versions: regsvr32 c:\windows\syswow64\msstdfmt.dll Don't ever download a DLL file from a website you're unfamiliar with. However, it's completely safe if you can manage to copy the file from the original location on a working computer. Update the drivers for hardware devices that might be related to msstdfmt.dll. If, for example, you're receiving a "The file msstdfmt.dll is missing" error when you play a 3D video game, try updating the drivers for your video card. The msstdfmt.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 msstdfmt.dll errors began after updating a particular hardware device's driver. 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 msstdfmt.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 msstdfmt.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 msstdfmt.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid msstdfmt.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 msstdfmt.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 msstdfmt.dll error using a troubleshooting step prior to this one. Troubleshoot for a hardware problem if any msstdfmt.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related. Need More Help?
