What are ITIRCL55.DLL Error Messages?


Dynamic Link Library ITIRCL55.DLL Errors

ITIRCL55.DLL is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ITIRCL55.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. Microsoft Office Professional Plus 2010 (64-bit)) could share the same ITIRCL55.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 ITIRCL55.DLL is attempted to be loaded either when Microsoft Office Professional Plus 2010 (64-bit) is starting up, or in some cases already running. Some of the most common ITIRCL55.DLL errors include:

Your ITIRCL55.DLL file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office Professional Plus 2010 (64-bit)), or deleted by a malware infection. Furthermore, ITIRCL55.DLL file corruption could be caused from a power outage when loading Microsoft Office Professional Plus 2010 (64-bit), system crash while loading ITIRCL55.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 ITIRCL55.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 ITIRCL55.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
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the ITIRCL55.DLL error, please proceed to the Step 2 below.

Step 2: If recently installed Microsoft Office Professional Plus 2010 (64-bit) (or related software), uninstall then try reinstalling Microsoft Office Professional Plus 2010 (64-bit) software.

You can uninstall Microsoft Office Professional Plus 2010 (64-bit) software by following these instructions (Windows XP, Vista, 7, 8, and 10):

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 ITIRCL55.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 ITIRCL55.DLL error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
