What are Appx.psm1 Error Messages?


General Appx.psm1 Runtime Errors

Appx.psm1 file errors often occur during the startup phase of Windows, but can also occur while the program is running. These types PSM1 errors are also known as “runtime errors” because they occur while Windows is running. Here are some of the most common Appx.psm1 runtime errors:

Microsoft Visual C++ Runtime Library

Program: C:\Windows\System32\WindowsPowerShell\v1.0\Modules\Appx\Appx.psm1

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


Most PSM1 errors are due to missing or corrupt files. Your Appx.psm1 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, Appx.psm1 file corruption could be caused from a power outage when loading Windows, system crash while loading or saving Appx.psm1, 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.
