This is an issue you should address.
If you are not an admin of the workstation, you have to run the installer as Admin. No problem.
However, WinRT Samples project is not installed to the user's AppData folder but to that of the admin account to which the user usually is not granted rights.
I'm the only user - the admin account is only for administration(!) - so, please, what is the recommended method to solve this - also for future projects.
I can go to Package.appmanifest and select tab Packaging, but no "Identity" is found here.
