Therefore, often Valorant players, and especially those who are new to this esports discipline, have problems solving Riot Vanguard errors. In this article we will look at the causes of Riot Vanguard errors and provide recommendations on how to fix them.

IF YOU ENCOUNTER REPEATED ERRORS WHILE LAUNCHING OR INSTALLING THE GAME, WE CAN HELP YOU

First, you should disable all existing antivirus programs, including the built-in Windows Defender. Additionally, it wouldn’t hurt to add the game to your exceptions list.

Check for all updates for your Windows system; some players find this helps!

For Windows 7 users (!)

Pay attention to the following updates:

However, since Windows 7 is already a very outdated version of Windows, we recommend upgrading to Windows 11, or at least to Windows 10, which has simplified versions that will minimally impact your system.

FAILED TO LAUNCH VALORANT or THE PROCESS IS ALREADY RUNNING

To solve this issue, you should install the latest version of the game installer and try the installation process again. Download link. (!) Important Download VALORANT only from the official website playvalorant.com.

If the problem persists after reinstallation, try navigating to the following directory in File Explorer: C:\Riot Games\Riot Client\ here we need to find a file named vcruntime140.dll . If you have this file, you must rename it to anything else (avoid Cyrillic characters). Done? Then restart Windows and try launching the game again.

If after all this, the problem still remains and you cannot enter VALORANT, try this: Go to File Explorer, click on the View tab, there will be a parameter Hidden Items, check the box next to it. Then go to C:\Users\your PC account name\AppData\Local\ here you will find the Riot Client folder, you need to click on it and archive it.

If nothing mentioned above helps, contact Riot Games support by providing all possible screenshots and detailing your issue, as well as describing the methods you tried to solve the problem. We hope you don’t need to contact Riot Games technical support and that the problem stops bothering you!
