Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally because of the mfc110u.dll error. Download the Visual C++ Redistributable for Visual Studio 2012 Update 4 package and run it. This action restores the mfc110u.dll with the most recent copy provided by Microsoft. You're given several download options from Microsoft for this update, based on the version of Windows you have installed—x86 (32-bit) or x64 (64-bit).

If you suspect that the mfc110u.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem. Uninstall every trace of the program from your computer. While you could use Control Panel to do this, a dedicated software uninstaller is better here since it forces the computer to delete every single trace of the program. You can then reinstall the program if the DLL error disappears after cleaning the application from the hard drive. If you've gotten this far and still have no luck fixing the mfc110u.dll error, try uninstalling the Visual C++ Redistributable from Step 1 as well as uninstalling the program in question. Then, return to Step 1, restart the computer, and then reinstall your program. Install any available Windows updates.

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 mfc110u.dll errors as they fail. If the hardware fails any of your tests, replace the memory or replace the hard drive. Repair your installation of Windows. If the individual mfc110u.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 mfc110u.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid mfc110u.dll registry entries that might be causing the DLL error. We rarely recommend the use of registry cleaners.

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 mfc110u.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 mfc110u.dll error using a troubleshooting step prior to this one. Troubleshoot for a hardware problem if any mfc110u.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related. Need More Help?
