- Hit the Windows key to open up the search bar.
- Type “Storage Settings” here.
- You will now get the following storage options:

How to fix “Failed to Receive Platform SIPT” error code in League of Legends
The League of Legends “Failed to Receive Platform SIPT” error usually occurs when you are either playing the game on an outdated patch or if the servers themselves are down for maintenance. Here are a few things that you can do to work around it:
- Make sure that the LoL client is updated to the latest patch and that you are not trying to launch the MOBA on an outdated version.
- Check if the servers are working optimally and are not down for maintenance by visiting the official LoL service status page.
- Restart your router or talk to your internet provider if the connectivity issue is from your end.
- Make sure that Windows Firewall is not blocking the client’s access to the server. Add LoL to the exceptions list to work around it.
- Activate or De-Activate VPN to see if that solves the error.
- Change your DNS by heading into Protocol Version 4 (TCP/IPv4) and then clicking on “Use the following DNS server address”. In the Preferred DNS server field enter 8.8.8.8 and for the Alternate DNS server enter 8.8.4.4. Then validate settings.
How to fix Error Code 7 in League of Legends
The League of Legends Error Code 7 occurs when the MOBA is seeing a huge surge of player log-ins. When the servers are overloaded with too many players, Riot will automatically try to manage the situation by not allowing more players to join in, thereby showing them the Erro Code 7 message.
There is unfortunately no solution for this apart from waiting it out till the servers are stable again and there is less of a player surge. You can visit the service status page for more information on the issue that the MOBA is facing.
How to fix “VAN 128 Vanguard error” in League of Legends
VAN 128 is an issue that stems from Riot’s Vanguard anti-cheat. It occurs when the software does not recognize your PC as a trusted system. It can also occur if you are running third-party security and cloud service tools that directly clash with the Kernel-level anti-cheat.
Here are a few things that you will need to do in order to solve it:
1) Make Vanguard find your PC to be trustworthy
You will be able to do this by:
- Making your way into Windows search and then typing “cmd”.
- Select the option to “Run as Administrator”.
- Once the command box pops up, type in the following and hit enter:
- bcdedit /set TESTSIGNING off
- bcdedit /set nointegritychecks OFF
- Restart your PC once done and then try logging into a custom game to see if the error has stopped occurring.
2) Try de-activating your system’s debugging settings
VAN errors can occur if the debugging default settings are switched on. You can solve this by:
- Tapping the Windows button and then bringing up the search. Here you will need to type in “sysdm.cpl”.
- Now in the pop-up head to the following directory: Advanced Tab > Startup and Recovery > Settings.
- You will now find the option to change the debugging information. So head there and change it to “None”.
- Once you are done with the above steps, make sure to restart your system and head into a custom match again to see if this solves the VAN 128.
3) Uninstall security tools
Third-party security solutions like Fasoo can be one of the causes leading to VAN 128. They directly clash with kernel-level anti-cheats and will not let you launch LoL. So uninstall these programs and then restart your system before logging into the client.
4) Disabling Cryptographic mechanisms
Client-sie programs like AWS Cloud Crypto usually clash with Vanguard. So if you have software like CryptoPro Cloud CSP installed, LoL will not launch,
So try to disable these apps or uninstall them before trying to launch the game.

How to fix the “Windows cannot access the specified device” error code in League of Legends
The “Windows cannot access the specified device” error is specific to Windows 11 users and stems from the Vanguard anti-cheat. Here are a few things that you can do to solve it:

- Once the pop-up opens look for an instance of LoL running by either manually scrolling for it or typing in its name in the search bar above.
- Select the instance and then click on “End Task.”
Another alternate way of making sure that you are closing all instances is to restart your system.
How to fix Error code 0xc0000005 in League of Legends
According to Riot, League of Legends Error: 0xc0000005 is more of a Windows issue than a client-side problem. So even the developers are pretty stumped at coming up with a permanent way of dealing with this performance bug.
Fortunately, running the MOBA as an administrator seems to have solved the issue for many. Alternatively, you can try the Hextech Repair Tool, but players suggest that running it as an admin is probably the best workaround for it.
How to fix “A critical error has occurred” in League of Legends
League of Legends “A critical error has occurred” occurs when there is an app with an overlay feature preventing you from logging into the client. For example, Discord has a Windows overlay feature which allows it to display your Discord party over the games.
This can block your access to the client, preventing you from logging in. To solve it you will need to:
- Disable apps that have an overlay feature. You can try to go as far as installing them if they are not necessary.
- Now, close the LoL client and then locate the installation directory of the game.
- Delete all of the config and data files from the directory.
- Finally, restart your system and then try logging into the client.

Once this is done, restart your PC and then try logging back into the client.
How to fix Error Code 002 in League of Legends

You can also use the Hextech Repair Tool to troubleshoot the problem if the issue persists.
How to fix “The program can’t start because d3dx9_43.dll is missing from your computer” error in League of Legends
This issue occurs for those users who have a new PC, or have formatted their PC and have re-installed Windows on them. The error means that you have not installed all of the Windows updates, which is why you are getting the d3dx9_43.dll error code.

How to fix “VAN error code 1067” in League of Legends
“VAN error code 1067” occurs when Vanguard fails to authenticate your system’s hardware. The error pop-up comes from the Trusted Platform Module (TPM 2.0) software which is a kernel-level program that starts as soon as you boot your PC.
The software goes over all your specs to authenticate your hardware. If it fails to authenticate, then TPM will show you VAN error code 1067.
There are multiple ways of solving this error code in League of Legends:
1) Enabling TPM through BIOS settings
- Restart your PC and head into the BIOS settings by pressing F2, F10, Esc, or Del when Windows is booting. The option you need to pick will depend on the motherboard that you are using. We suggest that you google it beforehand.
- When the BIOS loads make your way into the Security Tab and then look for the Trusted Platform Module (TPM) option.
- Enable it if it was not already and then hit on save changes.
- Now exit BIOS and restart your PC again before logging into the LoL client.
2) Enable TPM through UEFI Firmware Settings
- Restart your PC and instead of going to BIOS settings head to Windows Recovery Environment (WinRE) by pressing Shift + Restart.
- Now make your way to the following directory: Troubleshoot > Advanced options > UEFI Firmware Settings.
- Under the security tab, you will see the rusted Platform Module (TPM) and Secure Boost. Enable them both, then restart your PC before starting the LoL client.
3) Restart VGC services
VGC services getting restricted on your system can lead to VAN 1067. You can fix this by:
- Opening the Run dialog by pressing Win+R and then typing in services.msc” and then hitting enter.
- You will now gain access to a service window where you will find the VGC service. After locating it, double-click on it to start it.
- Now save the changes by clicking on OK before you exit.
Make sure to restart your system before launching the League of Legends client.
4) Close apps with overlays
Apps with overlays like Discord can cause the VAN error. So make sure to either disable or close the program altogether before booting up the League client.
5) Update Windows
Updating Windows 11 to the latest OS version seems to have helped many deal with the VAN Error Code 1067 in League of Legends. You search “Check for Updates” in the Windows bar for the latest version or press Win+I to open settings and under the Windows Update tab, check for updates.
