COUNTER STRIKE: CONDITION ZERO DELETED SCENES ERROR

Ok. Don't be scared. If this error will show to you, it's not aproblem.

1. Try to close steam. It's really important that thing, because you don't want to do some problems with another Half-Life bassed games.
2. You need to be sure you have Counter Strike Condition Zero Deleted Scenes installed! For this go to .../Steam/steamapps/common, and you need to see a folder with name [Half-Life 100]
3. Open [Half-Life 100] folder, and you will see [czeror] folder. Cut folder or drag in Half-Life folder!

4. Delete your [Half-Life 100] folder. Steam is off, but it will think you need to reinstall the game, or verify integrity files.

5. In your Steam folder, exatly -> ../Steam/steamapps/, you will see some [acf] files. You need to search [appmanifest_100.acf].

6. Right-click on this, and open with notepad, or any software to edit.

7. The notepad/software it's open, press CTRL+find and search [installdir]. Change from "Half-Life 100" to "Half-Life". Then, save it. If you open again and it's not changed: 1. Close Steam and retry. 2. Save as [.txt] in the same folder, then, delete [.acf] file, and rename [.txt] into [.acf] one!

8. Open Steam. Go to the Counter Strike Condition Zero Deleted Scenes, and open Properties.

9. On [boot option], type [“-game czeror”] (with the ““!).

10. Open, and enjoy the game!

GL & HF ALL!

From a Steam user, https://steamcommunity.com/profiles/76561197974105151, Max, i discovered something! If you change the version of game, it's chances to work, if the first step don't work for your PC.

And, you need to:
Step 1. Go to Library > Counter Strike: Condition Zero Deleted Scenes
Step 2. Go to Properties... (*right-click on the name-game)
Step 3. Go to [Game Versions & Betas] and change to [beta] or [steam_legacy - "Pre - 25 Anniversary Build"].

That's all! For more info please comment, and i will help you!
