Problems getting started

[acepleiades]

I followed the Getting Started tutorial up to the last step.
After unpacking SkyrimSE.exe with Steamless and replacing the executable, running the game through skse64_loader in MO2 will not open the game.
I tried to run the game with the normal SkyrimSE.exe, but it seems SKSE doesn't work in my game anymore, I get error 1 (it says it is not running).
The Steamless error may be because my Skyrim SE is shared through Family Sharing. I do not actually own Skyrim SE. I didn't get it for free when I could have (I have only bought LE). Could this be the case?

Late response, but when you unpack the game exe you need to pass the -forcesteamloader argument to skse_loader.exe
