I found the game files from some torrent, The game runs on windows 10, but its all in russian cause its missing
The eng.dat file. Could anyone send it so i can finally play this game ?
It's easy enough to find. :)
Go to GOG's gamepage
and click on the "Add to Cart" button. It should change to "Checkout Now" in which case click again (at time of posting, this was offered at a 75% discount - just $3.74).
You should now be on the checkout page - supply your payment details (credit/debit cards, PaySafeCard, WebMoney, Skrill and Paypal are accepted) and, if successful, you should get a confirmation page with a link to your GOG account.
Click on this link, and you should be taken to a listing of all your games purchased, which should now include Space Rangers HD (other versions of Space Rangers are available, but as you didn't specify in your original post I'm assuming you're after the latest version).
Click on the game name - a new window should appear. Make sure that English is selected as your language and then go to the bottom of this window where it says "Download Offline Backup Game Installers". If this appears as a button with nothing underneath, click it to get a list of individual files (this is GOG's way of trying to push Galaxy in your face, but you don't need it).
Click on the first 2 files listed (at the time of posting, 4 files were listed but the last 2 are patches for those with the previous version installed) to download. Store them somewhere safe on your system. There is an Extras section with 3 further files (Windows wallpaper, reference card and in-game music) that you can also download if you want - they aren't necessary though.
Once the downloads are complete, use Windows Explorer (or whatever file manager you prefer) to display these files and double-click on the first to start installation. This will include all the necessary files for English.
You should now have a working installation and the added satisfaction of having supported the developers of this game.
