What are mfc120u.dll Error Messages?


Dynamic Link Library mfc120u.dll Errors

mfc120u.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mfc120u.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. PaintShop Pro) could share the same mfc120u.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when mfc120u.dll is attempted to be loaded either when PaintShop Pro is starting up, or in some cases already running. Some of the most common mfc120u.dll errors include:

Your mfc120u.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with PaintShop Pro), or deleted by a malware infection. Furthermore, mfc120u.dll file corruption could be caused from a power outage when loading PaintShop Pro, system crash while loading mfc120u.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your mfc120u.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the mfc120u.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

CAUTION : We strongly advise against downloading and copying mfc120u.dll to your appropriate Windows system directory. Corel typically does not release PaintShop Pro DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing mfc120u.dll and all other DLL files for PaintShop Pro. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
