Valorant ‘Invalid Access to Memory Location’ Error: How to fix in 6 Ways

There are various ways to fix this issue on your PC but the most common one seems to be downloading and re-installing the game from the correct resources. Follow the list below to get you started. 

1. Re-download and Update from Riot Client

The Riot Client is designed to check your Valorant installation every time it boots up. The first start-up of a fresh install will help manually start this process which should help solve issues with Valorant on your PC. The Riot PC client installs with the game itself, so you must already have it installed on your PC.

Open the Riot app on your PC, and it shall automatically start verifying your Valorant installation. However, if you have an outdated client then your client will be updated first, and subsequently, once updated, the new client will check and verify your installation. 

Most users have managed to fix their ‘invalid access to memory location’ error by doing the same. The Riot Client will automatically find and replace corrupted files in your local installation. It will also look for mismatched configurations, permission conflicts, and missing files on your PC and replace the same if needed. We highly recommend you Restart your PC after the Riot Client has finished checking and replacing all the affected files for good measure.

2. Restart PC

This might seem redundant but a restart seems to do wonders if you are facing the ‘invalid access to memory location’ error on your PC. It seems that mismatched permissions can cause this error on modern Windows 11 PCs and a recent Windows update is most likely to blame. A restart helps get everything sorted by resetting services, restarting background tasks, clearing caches, setting the proper permissions, and more. We recommend you restart your PC at the earliest and check if the issue has been fixed for you.

3. Don’t use VPN

We highly recommend you avoid using a VPN when trying to launch Valorant on your PC. The game relies on your account information, current location, and ISP to assign you the best possible servers, and having a VPN turned on can mess up the same. Mismatched location data, ISP information, and IP addresses can also lead to the ‘invalid access to memory location’ error. Hence if you have an active VPN configured on your PC or router, then we recommend you disable the same to fix this issue for you. 

4. Re-install Valorant

At this point, if you are still facing the ‘invalid access to memory location’ error then Valorant’s local installation seems to be more broken than we anticipated. We now recommend you simply uninstall Valorant from your system, restart your PC, and then reinstall the game. A fresh installation will help fix this issue for you while your Riot account will help restore all your progress.

If however, a Re-install of the game still does not fix the issue for you, then you can troubleshoot your PC using the subsequent fixes. In the rare case that you are still unable to fix your issue then we’d recommend you submit a support ticket with Riot games using the last section in this post. 

When reinstalling Valorant, we recommend you follow the following steps:

  • Remove Vanguard 
  • Remove Valorant & Riot client
  • Restart PC
  • Re-install Vanguard and Valorant (ensure that everything is sourced from the Riot Client)

Additionally, here are a few more tips that should help you avoid known errors and bugs for Valorant on Windows 11. 

  • Install the game in a different partition from your boot partition
  • Disable any third-party cleaners, optimizations, or RGB apps that detect and profile games on your PC. 
  • Disable full-screen optimizations once Valorant has been re-installed
  • Disable any overlays and capture services when launching Valorant for the first time. 

These tips and the steps above should help you get a fresh installation of Valorant on your PC which should work as intended. If however, you still get the ‘invalid access to memory location’ error on your PC then it could be an issue related to your system.
