How to Install a Windows Phone app that is no longer published?

[Nokia Boy]

So recently i tried a game,however it recently got unpublished but im still able to download the xap from windowsphone site,but when i try to install it (going to Files app,and opening the xap) it says "Can't install company app". So can i install the xap without being published?

Install Visual Studio Community, and/or use the WP app deployment tool.

Can you install other official xaps this way?

Try screenshoting the error message

It can deploy apps extracted from from the device,but not xaps from windowsphone site

Try renaming to a name without foreign characters, try downloading again, and try dev unlocking your phone again

Try taking out the SD card, reading it externally, then copy the xap to an app folder

What do you mean man?

Read the card using an SD reader, not the phone.
