The error message you could see may vary but typically, it would read:
PowerShell Get-Appxpackage Not working
It’s a permission issue that can be resolved by following some checks. When changing the permission of folders, make sure you do not remove any user account which is already available.
1] Run PowerShell With Admin Permission
Since the command needs to install on the application on a system level, it is important that you execute or run the command when it is launched with admin permission.
Press the Start button, and type PowerShellWhen it appears on the list, right-click and choose to Run as AdministratorExecute the command and it should work without error.
Apart from permission denied, you may also receive Not Recognized or Not Working as an error. While Not Recognized is related to admin permission, Not working is related to Services. Go to Services Snap-in, and locate Client License Service (ClipSVC) and AppX Deployment Service (AppXSVC). Make sure they are available and running.
2] Check Permission With Destination Directory
If you are installing the application in a particular folder, then make sure you have complete permission to write the files inside it.
Go to the Destination folder, right-click and select PropertiesThen switch to Security tabCheck if your account is available, and it has full permission.You need to also check if the System user account is available and has full controlIf not, you can click on the Edit button, and add them along with the permission.
3] Check AppX Deployment Service status
In the PowerShell console, Run Get-Service “AppXSvc” and see. The AppX Deployment Service (AppXSVC) Status should be Running. If it shows Stopped, then open a command prompt as administrator and run: Alternatively, you could open Regedit and navigate to: Here set the value of “Start” to “3” and reboot. Post these changes, you can execute the command, and the error should not occur anymore. Read: How to change File and Folder permissions in Windows.
