Today we'll talk about why Dota 2 won't launch. Dota 2 can be considered one of the most popular MOBA games to date. A huge number of people are fans of the project due to the fact that each new round is not like the previous one, and events can be completely unpredictable.

About why Dota 2 doesn't start

There are several reasons that prevent the game from starting. Firstly, this may be due to the release of the update. Dota upgrades once a week automatically. There are times when an update needs to be started manually. To open the game, you need to exit the main menu, go to your Steam library, find Dota 2 in the list, right-click on it once and click "Update". AfterAfter completing these steps, the download will begin and after some time the application will start without problems. In order not to do all these steps every time the developers release an update, you should enable the "Automatic update" function in the Steam settings.
If this is not the problem, you can try restarting Steam. Also, if you are a Windows XP user, you can try opening the application as an administrator.
If Dota 2 still refuses to start, then you can try to completely reinstall the game and the Steam program.
