Key notes

When it comes to the Steam service, Dota 2 is untouchable in the number of active participants. With vivid graphics and immersive gameplay, it is an amazing multiplayer experience.

Nevertheless, software without bugs is a non-existent, unicorn-like category. So, yes,Dota 2 has its technical issues. One of the issues that seamlessly showed up was the game launch failure.

Most of the time, the crash is followed by theFailed to Start Game (Missing Executable)message.So, we’ve prepared some possible solutions for this annoyance.

What to do if Dota 2 fails to start

1. Let the Steam tool verify game files

Corrupted/incomplete file issues can be quite a challenge for some older titles. Back in the day, you would probably have to reinstall the game in order to make it work.

This is not the case with Steam nowadays. With the implemented File integration tool, you can check and fix any game in your library.

2. Tweak Antivirus

Antivirus/antimalware/antispyware programs are known causes for Dota 2 malfunctioning. The last resort would be disabling them while playing thegame. However, if you are attached to your security, try out these tweaks:

3. Disable background applications

There are reports that some background processes interfere with the client and thegame. The ones that are most problematic are connection-dependent.

Besides the already mentioned antivirus programs, you should look out for firewall software, torrent clients, VPN and proxy software, VoIP apps, and IP masking programs. Be sure to disable them before you start theSteam client.

4. Reinstall Dota 2

The last step you can try to follow through is a complete reinstallation. In addition, make sure that your graphics drivers are up to date and also redistributables and DirectX. Reinstalling a Steam game is a rather simple task, as shown above.

Of course, re-downloading might be a drag if you have a slow bandwidth. The game should work better afterward.

If none of these solutions actually worked, you shouldsend the Steam Support Ticket. That way, Steam technicians can address the issue and provide additional details.
