What are A0000028.rbf Error Messages?


Dynamic Link Library A0000028.rbf Errors

A0000028.rbf is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like A0000028.rbf, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like accicons.exe - to follow. These files were created so that multiple programs (eg. Office) could share the same A0000028.rbf 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 RBF 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 A0000028.rbf is attempted to be loaded either when Office is starting up, or in some cases already running. Some of the most common A0000028.rbf errors include:

Your A0000028.rbf 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, A0000028.rbf file corruption could be caused from a power outage when loading Office, system crash while loading A0000028.rbf, 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 A0000028.rbf 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 A0000028.rbf issue. These troubleshooting steps are listed in the recommended order of execution.

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 A0000028.rbf 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 A0000028.rbf 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 A0000028.rbf 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 A0000028.rbf file version.

  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows XP.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve A0000028.rbf problems.

If you are not currently backing up your data, you need to do so immediately.



Download A0000028.rbf Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying A0000028.rbf to your appropriate Windows system directory. Microsoft typically does not release Office RBF 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 A0000028.rbf and all other RBF files for Office. An incorrectly installed RBF file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
