You do not need STALKER to run LA, Stand alone Release. Download all 4 parts, and use winrar or winzip to unpack them, then run setup.exe and follow the instructions. Enjoy & PLEASE THANK THE HARD WORKING DEVELOPERS!
Anyone who uses 32bit operating system should remove the msvcp120.dll, msvcp120d.dll and msvcr120.dll from the game's bins directory. That will solve many problems. Also before game start, you can delete the user.ltx too and let the game create a new one based on your system specs.
If you guys dont have admin priviliges on your pc or dont have UAC disabled, then do not install the game to the default program files directory (its protected by windows)!
Install it to an other drive, or an other dir, otherwise you wont be able to save, load, or make screenshots. We will try to find out something for this in the upcoming patch.
Also you should disable actor legs in options menu, as soon as you can, because it causes 3 troubles: 1 missing step sounds, 2 crash with missing bone, 3 crash when fighting rats.Thanks for your understanding and support!
