Language problem in STALKER: Shadow of Chernobyl

Hello everyone! Help with the problem. Today I bought Stalker Shadow of Chernobyl (version 1.0006), hoping to pass it. But when I launched it, I saw that the menu and the game were in English. I was looking for a solution to this problem and the solution was to install the Russifier, but people said that the Russifier is worse than the usual official Russian version. What to do? Thanks in advance!
