Come see Elena during the daytime. Not through the house map, but up the stairs, through the corridor, to her door. When you get there, you'll find that her laptop's operating system is down. You reinstall it, then download some photo editing software from a pirate site. That's the whole computer “repair” thing.
But it looks like you don't have the hints turned on. Click on the magnifying glass above the notepad.
This is an unplayable mess for me. I downloaded the game again from a different mirror, and now it doesn't throw the immediate error I had before, but there are no images at all, and no matter what I do, I get error after error.
So for whatever reason the game has taken a personal offense to you

100% a problem with the game on your end.
A few possible reasons why the game on the Ren'Py engine does not start and displays only a dark screen:
Faulty graphics drivers. It's worth checking if there are updates for your graphics card drivers.
Power saving enabled. In one case, the problem was not the graphics, but the fact that power saving was enabled.
DirectX or the Redistributable Microsoft Visual C++ 2010 package is not installed.
The game is placed in a directory with a full path that does not match the current system language. For example, if Ren'Py is in a directory with Cyrillic or Arabic alphabet in its name and the system is set to English, the game will not run.
I passed both published parts of the remaster without a single error message. The walkthrough is very easy, the main thing is to turn on the hints.
