What is causing the This app can’t be activated by the built-in administrator error?
This particular error occurs because of a security setting of the recent Windows versions have. Certain file types that are opened through Store apps will require UAC permissions in order to run. Since the built-in account doesn’t have UAC (User Account Control) privileges, you’ll see the “This app can’t be activated by the built-in administrator” error instead. This change was introduced on Windows 7, Windows 8 and Windows 10 in the months following the launch of Windows 10 via a security update. So, the “This app can’t be activated by the built-in administrator” error is not actually an error, but a security feature that Microsoft introduced to patch some vulnerabilities. However, there are ways to configure your machine in order to circumvent this.

The procedure below involves using the Group Policy Editor to enforce the User Account Control: Admin Approval Mode for the Built-in Administrator account. Follow the steps below to get this done: Note: Keep in mind that not all Windows versions include the Group Policy Editor utility. Typically, Home and Student editions of Windows 7, 8.1 and 10 will not include this tool. However, you can add the Group Policy Editor to Windows Home Editions by following this article (here).
