How To Fix Mfc71.dll Errors

Reader Question:
“Hi Wally, How do I fix the Mfc71.dll error, it appears when I try to restart my computer.” - Lindsay R., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: There are several different ways that Mfc71.dll errors can show up on your computer. Here are some of the more common ways that you might see Mfc71.dll errors:

What does the Mfc71.dll error look like?

  • “Mfc71.dll Not Found”
  • “Unable to locate component mfc71.dll”
  • “BCMWLTRY.EXE – This application has failed to start because MFC71.DLL was not found.”
  • “This application failed to start because MFC71.DLL was not found. Re-installing the application may fix this problem.”

When does the Mfc71.dll error appear?

Mfc71.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 Mfc71.dll error is an important piece of information that will be helpful while solving the problem.

Causes of Mfc71.dll error

Mfc71.dll errors are caused by situations that lead to the removal or corruption of the msvcp71 DLL file.

In some cases, Mfc71.dll errors could indicate a registry problem, a virus or malware issue, or even a hardware failure.

How To Fix Mfc71.dll Errors

Note: Start Windows in Safe Mode to complete any of the following steps if you’re unable to access Windows normally due to the Mfc71.dll error.

  • Restore Mfc71.dll from the Recycle Bin - The easiest possible cause of a “missing” Mfc71.dll file is that you’ve mistakenly deleted it.
  • Recover the file - If you are sure that you deleted it and emptied the Recycle Bin as well then you could restore it using a data restore utility. The recovery of your file depends on the amount of activity on the disk partition after the deletion of the file.
  • Run a virus/malware scan - Install an anti-virus or anti-malware software, and scan your whole computer. If a virus or malware caused the error then removing it might solve the problem.
  • Use System Restore - Use it to undo recent system changes. If you suspect that the Mfc71.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem.
  • Reinstall the program - Reinstall the application that is giving this error.
  • Update the drivers - If it is a hardware issue e.g. caused by the video card. Note: The Mfc71.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.
  • Rollback a driver - If updating a driver caused the problem.
  • Run the sfc /scannow System File Checker command - Do this to replace a missing or corrupt copy of the Mfc71.dll file. If this DLL file is provided by Microsoft, the System File Checker tool should restore it.
  • Install Windows updates - Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The Mfc71.dll file could be included in one of those updates.
  • Repair Windows installation - If the individual Mfc71.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.
  • Registry Cleaner - Scan your computer with a registry cleaner utility such as WinThruster to repair Mfc71.dll related issues present in the registry.
  • Perform a clean installation of Windows - A clean install means to erase all data on the hard drive before installing again Windows. If all else fails. This might still work. You should back-up your documents, bookmarks, videos, etc before doing this.
  • Hardware Check - If the problem persists after a clean Windows installation, then Run a diagnostic check of your hard drive and memory. You can run the built-in diagnostics utility of your computer by referring to the manual. You may also find a free diagnostic utility online. If a severe problem is discovered in the diagnostic test, replace the hard drive or memory as soon as possible.
  • Troubleshoot for a hardware problem if any Mfc71.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.
