The termination of the installation or update process of an app may corrupt it. In this case, the user may get an AppModel Runtime error 69 on launching that specific app. Follow the procedure listed below to get rid of this error:

1. Take ownership of the WindowsApps folder. You will find this folder at C:\Program Files\WindowsApps location.
2. Now, open the WindowsApps folder and look for the folder name of the app that is causing the problem. For example, the folder for the People app is created under the name Microsoft.People.
3. Run PowerShell as administrator, type the following command, and press Enter.

get-appxpackage *Microsoft.People* | remove-appxpackage

In the above command, replace “Microsoft.People” string with the app name or string that is causing the problem. Restart your computer. After restart, visit the Microsoft Store and install the particular app again.

When you are done, give the MicrosoftApps folder’s ownership back to the TrustedInstaller.

Fix AppModel Runtime error 79

The cause of AppModel Runtime error 79 is corrupted system files or missing/broken application components. The following solutions may help you fix this error:

1. Run SFC and DISM scan.
2. Execute a command in Windows PowerShell.

1] Run SFC and DISM scan

SFC (System File Checker) is a utility that scans and repairs the corrupted files in the system. Open the Command Prompt as an administrator, type sfc /scannow, and press Enter. You should wait till the scanning gets completed. If the SFC scan doesn’t fix the issue, open the Command Prompt again as an administrator, paste the following command, and press Enter:

dism /online /cleanup-image /restorehealth

2] Execute a command in Windows PowerShell

Launch Windows PowerShell as an administrator, paste the following command, and press Enter:

ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage Microsoft.Windows.Photos).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"

In the above command, you have to replace the string “Microsoft.Windows.Photos” with your Broken app. We have written this string here just for an example. Let’s say, if the broken app is People, you have to type “Microsoft.People.” How could you know that? Visit the following path on your computer and search the name of your broken app:

C:\Users\username\AppData\Local\Packages

That’s it. We hope this article helped you solve the problem.
