What are AppxPackageManager.admx Error Messages?


General AppxPackageManager.admx Runtime Errors

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

Most ADMX errors are due to missing or corrupt files. Your AppxPackageManager.admx 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, AppxPackageManager.admx file corruption could be caused from a power outage when loading Windows, system crash while loading or saving AppxPackageManager.admx, 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.

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".

  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.

  4. You'll be prompted with a permission dialog box.

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