What are A0000027.dll Error Messages?


Dynamic Link Library A0000027.dll Errors

A0000027.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like A0000027.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like SCANOST.EXE - to follow. These files were created so that multiple programs (eg. Office) could share the same A0000027.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 A0000027.dll is attempted to be loaded either when Office is starting up, or in some cases already running. Some of the most common A0000027.dll errors include:

Your A0000027.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Office), or deleted by a malware infection. Furthermore, A0000027.dll file corruption could be caused from a power outage when loading Office, system crash while loading A0000027.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.



How to Fix A0000027.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your A0000027.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.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many A0000027.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  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 A0000027.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your A0000027.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate A0000027.dll file version.

  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve A0000027.dll problems.

Download A0000027.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying A0000027.dll to your appropriate Windows system directory. Microsoft typically does not release Office 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 A0000027.dll and all other DLL files for Office. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
