After resetting the data for my app locally and then deleting it I encountered the following error: “DEP0700 : Registration of the app failed. Another user has already installed a packaged version of this app. An unpackaged version cannot replace this. The conflicting package is xxx and it was published by CN=xxx.”

For some reason the app was still on the system for another user. I ended up having to run powershell as an administrator and running the following snippet to delete the app completely from the system:

get-appxpackage -all | where name -eq “17402Qua.xxx” | remove-appxpackage
