What are about.xaml Error Messages?


General about.xaml Runtime Errors

about.xaml file errors often occur during the startup phase of Windows, but can also occur while the program is running. These types XAML errors are also known as “runtime errors” because they occur while Windows is running. Here are some of the most common about.xaml runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_6.3.9600.20278_x86__8wekyb3d8bbwe\views\about.xaml

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


Most XAML errors are due to missing or corrupt files. Your about.xaml file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, about.xaml file corruption could be caused from a power outage when loading Windows, system crash while loading or saving about.xaml, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix about.xaml 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 about.xaml 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 about.xaml error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing about.xaml file.

System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt about.xaml files (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "cmd" but DO NOT PRESS "ENTER".
  3. Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
  4. You'll be prompted with a permission dialog box.
  5. In the box, click "YES".
  6. You should have a black screen with a blinking cursor.
  7. In that black screen, type "sfc /scannow" and hit "ENTER".
  8. SFC will begin scanning for about.xaml issues and any other system file problems.
  9. Follow any on-screen commands to complete the process.

Please be aware that this scan might take a while, so please be patient while it is working.

If this Step 2 fails as well, please proceed to the Step 3 below.

sfc /scannow

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

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

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



Download about.xaml Files (Malware-Tested 100% Clean)


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