The game crashes as soon as I arrive at the orange ScummVM screen----it just shuts down on its own. My specs are windows 7, x-64, inspiron 620, intel i5-2320.
I did use GoG Galaxy to download and install the game. Has anyone else encountered this problem before?

Is there any specific error prompt?
Could you check if the following suggestion is of any help?
https://www.gog.com/forum/blade_runner/crashes_on_launch/post2

I did download a dev version of ScummVM from the link you provided and I was able to get Blade Runner to start playing, but an error screen kept on popping up. It has something to do with an assertion failing---apparently there's something wrong with the expression _mixerReady.

Assertion failed!
Program: C:\Users\Tudor\Downloads\mingw-w64-master-latest(1)\mingw-64-master-5b10413b\scummvm.exe
File:-/-/src-master/src/audio/mixer.cpp, Line 238
Expression:_mixerReady

Could you attach your scummvm.log file if possible?
It should be located here:
%APPDATA%\ScummVM\Logs\scummvm.log

Also, when the game launches, is there any sound playing at all?

GOG won't let me attach log files, so I've copied and pasted the whole thing here. There isn't any sound playing when the game launches because the speakers are unplugged at the moment---is it possible to play through this game successfully without any sound?

it does the same thing for me too, win 7 64 i7 4790k and i'm not using the galaxy version

ok this is really strange because its working now and i don't know what i did, it was crashing at startup yesterday every time i tried starting the game but not anymore. i booted up the game to see what exactly the error message was (it had something to do with the scummVM thing) but all is well now, thanks for replying and trying to help :)

I just plugged the speakers in and the error prompt no longer appears now, and the subtitles are appearing both for the cutscenes and the dialogue. The game seems to work fine so far, thanks for all the help!
