As of late, there are a couple of Store apps which just won’t install on any of my Windows 10 machines (One Commander and Open Live Writer in case you are interested).
The message shown is:
The error code is 0x80073CF9, in case you need it.
If you do a search on the error number you’ll find numerous posts and articles explaining on how this error might be solved. As it happens, the error also occurs on Windows Phone/Mobile systems.
One of the suggestions I came across is re-installing the Store app.
Uninstalling a Modern App is quite easy with tools like CCleaner. If you don’t have tools like this, it’s also possible to do this via the PowerShell Remove-AppxPackage cmdlet of course.
However, once uninstalled, how will you install the Store, without having a Store.
A System Restore might help, but I didn’t have any usable restore points.
An easier solution is to re-install the Store app via PowerShell. With the following command you will see all the applications which still reside on your system.
Get-AppxPackage -allusers | Select Name, PackageFullName
One of these should have a name similar to Microsoft.WindowsStore.
You can re-install this app by using the Add-AppxPackage cmdlet.
Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsStore_11610.1001.25.0_x64__[uniqueId]\appxmanifest.xml" -DisableDevelopmentMode
Invoking this command, mind the [uniqueId] which differs on every system, installs the Windows Store again. You will be able to find the Store again in your start menu/screen and start it again. The error still occurs when trying to install these specific apps, so re-installing didn’t solve my issue.
