I can install this app using the .appxbundle, but when I try to run the .appinstaller file locally, I get the following error:

Cannot open app package: An error occurred while accessing the file from the web. Please try downloading and opening the file locally.

I am able to load both the .appinstaller and .appxbundle from the browser by navigating to the addresses defined in the .appinstaller file.

  • Could share your xml content about appinstaller file? – Nico Zhu Jul 15 '19 at 08:34
  • Due to network isolation, Windows 10 apps like App Installer are restricted to use IP loopback addresses like http://localhost/. When using local IIS Server, App Installer must be added to the loopback exempt list. For more please refer this [document](https://learn.microsoft.com/en-us/windows/msix/app-installer/web-install-iis#step-8---add-loopback-exemption-for-app-installer). – Nico Zhu Jul 16 '19 at 07:25

Right click the downloaded .appinstaller file and select Properties. At the bottom of the Properties window, check the 'Unblock' checkbox then click ok. Rerun the .appinstaller file and it should now install the program.
