Released in 2016, the continuation of the game Doom caused the expected furor. However, as is customary among developers lately, the game was released in its "raw" form, and the refinement took place "on the knee". Because of this, there are a huge number of errors in it, due to which Doom 4 does not start or works every time.

Pirate
First of all, let's divide the errors that occur according to some attribute. And let's start with those people who prefer to download pirated versions of games from the Internet, rather than buy them in the store. Since the original application is hacked to create a pirate, some files may be damaged during this process. What to do if your pirated Doom 4 won't launch?
- Check if the installation is correct. The unlicensed version may be missing certain system files that are installed with the application. In this case, you need to download and install them separately.
- When buying a game through "Steam" part of the necessary software is installed at the first start, if Doom 4 does not start, try to check the installed drivers. MS Framework and MS Visual C++ latest versionsmust be in the system.
- Sometimes Doom 4 won't launch due to graphics and video card issues. In such cases, you need to update your graphics card drivers or download related software. For example, GeForce Experience.
- Antivirus can also block the game from accessing the internet or from running it. Try adding Doom 4 to the exceptions or disable your antivirus completely.

License
It's a different story with games bought from official marketplaces. If you purchased a disc with the game, then you may experience problems due to an outdated version. When Doom 4 won't launch, you should check your internet connection. The game may be trying to update before being presented to its "master".
If Doom 4 doesn't launch on Steam, it could be for a variety of reasons, including those already mentioned. For example, the path to the game should not contain Russian letters. Since applications downloaded through Steam are installed in its folder in most cases, you should also check the location of the client.
Also be sure to check the free space on your hard drive. You may have problems if it was not enough when downloading and automatically installing through Steam. You may need to completely reinstall the Steam client and the game, as the hard drive memory cells may be damaged.

System
What else is worthcheck if Doom 4 won't start? Sorry something wrong is an error that often appears in front of the players. This means that you are most likely using a pirated version of the game, since you can only run 5 copies per day on different computers with one license key. You can't do anything with it unless you find another repack. If a similar problem arose with the license, then you are using a non-standard modification.
Also, if Doom 4 won't launch, be sure to check the system requirements. Modern games consume a lot of computer resources, so if they do not match, they may not work even on relatively new machines. In such a situation, you can try using third-party software that speeds up your computer.
