Again, do you have allowed your phone to install Apps from outside the store in Settings, Update & Security, for Developers?
Without that Option your Phone will Never install the App.

Yes, as you told me, I have enabled it, but it still cannot install the Appx file.
Am I following the correct procedure here:
First I go to Microsoft Store, search for Lumia Camera, this is the link what I get (btw, there are two Lumia Camera apps available there):
[URL="https://www.microsoft.com/en-us/p/lumia-camera/9wzdncrfjbf9"]https://www.microsoft.com/en-us/p/lumia-camera/9wzdncrfjbf9

For this Lumia Camera is says 'This app is for Windows Phone 8.1. For Windows 10 devices, the built-in Camera app works best.'

Then I enter that link into https://store.rg-adguard.net/
and there I download the file with appx extension (Microsoft.MicrosoftLumiaCamera_2015.1022.1227.410_neutral_~_8wekyb3d8bbwe.appxbundle)
I then transferred the file on Lumia, and with Total Commander I go to a folder where I placed the file and click on it, it offers Install option, but it then does nothing.

Btw, there is another Lumia Camera app in Windows store: https://www.microsoft.com/en-us/p/lumia-...zdncrfhww1
For this one there is no warning message that it's for Windows Phone 8.1
But if I enter that link into https://store.rg-adguard.net/ I don't get appx file, only this file without extension: [URL="http://tlu.dl.delivery.mp.microsoft.com/filestreamingservice/files/029adfa2-9f8b-48c2-b47d-cb9360fd79ad?P1=1578236735&P2=402&P3=2&P4=ITr6TtVAElivqb5rNAz5731UjXxkkF0BYwZF7DTJH4bQlKq65L79rRxcnTREOztQ8Kk4VsqV%2fHpH1%2ba1JpZ7DQ%3d%3d"]029adfa2-9f8b-48c2-b47d-cb9360fd79ad
