Error registration with application error in the Windows Store or Universal application

Visual Studio shows the following error while running my Windows Store or Universal project:

Error 1 Error: DEP0700: Application registration failed. Another user has already installed an unpacked version of this application. The current user cannot replace this with the packaged version. The conflicting package is dff9bf13-e639-46ad-a6ed-61b27be58eed, and it was published by CN = owais. (0x80073cf9) tiles

You are probably trying to install the application on your already installed computer. You may have installed it once during development and are now trying to install it either from another account or using a different deployment method.

There are several ways to fix this.

Best way: Uninstall an installed application, for example. using Powershell Remove-AppxPackage and specify the package, and then try reinstalling.

Another way: Change the name of the package in Package.appxmanifest of the application you are trying to install, compile and install again.

Example:

 <Package ...> <Identity Name="5a0c511a-fdfd-4417-80b8-2bedbf437971" ...>

change to:

 <Package ...> <Identity Name="5a0c511a-fdfd-4417-80b8-SomethingElse" ...>

Use the Powershell Remove-AppxPackage to remove the old package. If the package was installed by another user, run as administrator and use the -AllUsers switch. Find the full package name by package name using Get-AppxPackage .

For example, if the package is Contoso.ZiplineSimulator , use this command to find it:

 Get-AppxPackage -AllUsers Contoso.ZiplineSimulator

Then remove the package with any displayed PackageFullName , something like this:

 Remove-AppxPackage -AllUsers Contoso.ZiplineSimulator_1.53.2912.0_x64__8wekyb3d8bbwe
