I carried out Android development on a desktop with VS2019, generating successive ad-hoc APK files for installation. Unfortunately I've had to relocate overseas and set up a new development platform, bringing my development files and documentation with me, but not the machine. When I set up my certificate today using the exact alias name, input fields and password, the resulting APK file will not install over the top of the existing mobile app.
App not installed - An existing package by the same name with a conflicting signature is already installed
I realise why this is, but is there no other way to set up the certifcate without getting the originals from
%appdata%\local\Xamarin\Mono for Android\Keystore?
