The easiest possible cause of a "missing" mfc42.dll file is that you've mistakenly deleted it. If you suspect that you've accidentally deleted mfc42.dll but you've already emptied the Recycle Bin, you may be able to recover mfc42.dll with a free file recovery program. Recovering a deleted copy of mfc42.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.

It's even possible that the mfc42.dll error you're seeing is related to a hostile program that's masquerading as the file. Run the sfc/ scannow System File Checker command to replace a missing or corrupt copy of the mfc42.dll file. Since this DLL file is provided by Microsoft, the System File Checker tool should restore it.

If the mfc42.dll DLL error occurs when you use a particular program, reinstalling the program might replace the file if it's missing, or reassociate it with the DLL file if it isn't missing. Update the drivers for hardware devices that might be related to mfc42.dll.

If, for example, you're receiving a "The file mfc42.dll is missing" error when you play a 3D video game, try updating the drivers for your video card. The mfc42.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 mfc42.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 mfc42.dll errors as they fail.

A free registry cleaner program may be able to help by removing invalid mfc42.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). We've included the option here as a "last resort" attempt before the destructive step coming up next.

Make sure you've made the best attempt possible to fix the mfc42.dll error using a troubleshooting step prior to performing a clean install. Troubleshoot for a hardware problem if any mfc42.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.
