VALORANT VAN Restriction 5 Fix: HVCI and Secure Boot
Check the exact Windows security blocker, fix it in the safest order and get Vanguard ready without guessing through random BIOS settings.
What does VAN Restriction 5 mean and how do you fix it?
VAN Restriction 5 means HVCI, shown in Windows as Memory Integrity, cannot initialize in the security state required by Riot Vanguard. Start in Windows Security, not in VALORANT settings. Check Device security, Core isolation and Memory Integrity. If Windows lists incompatible drivers, update or remove the real blocker through trusted channels.
Then verify that Windows uses UEFI with Secure Boot enabled. Check virtualization and NX/XD only when the Vanguard message or Riot guidance points there. Restart fully after each completed change. This is a device restriction, not an account ban.
Fix Vanguard first. Then upgrade the account.
Once the PC launches cleanly, compare region, rank and inventory.
A different account does not fix a Vanguard device restriction.
Vanguard is blocking the device security state
VAN Restriction 5 appears before the normal game flow because Riot Vanguard checks whether required Windows and firmware protections are available. If HVCI cannot initialize, Vanguard can stop VALORANT before you reach the lobby.
That distinction matters. Reinstalling skins, changing graphics settings or signing into another Riot account does not repair the security layer. The fix belongs to Windows, a driver or the device firmware.
Memory Integrity cannot start in the required state.
An incompatible low-level driver can stop the toggle.
UEFI, Secure Boot, virtualization and NX/XD can matter.
Make one verified change, restart and retest.
Check Windows before you enter the BIOS
The safest first pass uses tools already built into Windows. Record each result before changing anything so you know which requirement is actually failing.
Memory Integrity protects the Windows kernel
HVCI stands for Hypervisor-protected Code Integrity. Microsoft presents it as Memory Integrity inside Core isolation. It uses hardware virtualization to isolate code integrity decisions and makes it harder for malicious or untrusted low-level drivers to modify the Windows kernel.
If Memory Integrity refuses to turn on, Windows often identifies a driver that is not compatible. The useful fix is to update that driver or remove the unused software or device that installed it. Downloading a random replacement driver creates a larger security problem.
Enable it, restart Windows fully and launch VALORANT again.
Use Windows Update or the official hardware manufacturer.
Hardware virtualization may be disabled or unsupported.
Collect the error and use Riot or device support.
Secure Boot, TPM, virtualization and NX/XD are connected
Secure Boot and TPM 2.0 can already be enabled while VAN Restriction 5 remains. HVCI also depends on virtualization support, and Riot’s error guidance can point to NX/XD execution protection. BIOS names differ between manufacturers.
Windows must report the correct state. Legacy or CSM mode needs careful manufacturer guidance.
Confirm it with Windows tools before assuming the firmware setting is correct.
The label varies by CPU and motherboard, so use the exact device manual.
Different firmware can use different names for the same class of protection.
Use one controlled change at a time
This order starts with the reversible Windows checks and moves toward firmware only when needed.
Read the full VAN message and make sure it specifically says Restriction 5.
Finish pending Riot, Vanguard and Windows updates with a full restart.
Open Core isolation and record whether the toggle is off or blocked.
Update the named driver through trusted Windows or manufacturer channels.
Use msinfo32 to check BIOS Mode and Secure Boot before entering firmware.
Use the device manual for virtualization, TPM and NX/XD when required.
Launch VALORANT after the completed change before adjusting anything else.
Send Riot Support the exact error, system details and checks already completed.
Your setup works. Now choose the inventory.
Shop around the region, rank and skins you actually want to play.
Do not trade one launch error for a security problem
Unknown scripts can change security, drivers and registry settings without explaining the result.
The goal is to satisfy the required protection, not weaken the device until the message disappears.
Identify the device or software behind the incompatible driver before removing anything.
Menu names and safe settings differ across vendors, models and firmware versions.
Vanguard checks the PC. The same device restriction can block every Riot account on it.
Match the next step to what Windows shows
Check Windows Update, Device Manager and the device manufacturer’s support page.
Confirm UEFI, disk layout and the manufacturer’s exact Secure Boot instructions.
Use the device manual and Windows system information before changing firmware.
Include the full error, Windows version, motherboard or laptop model and completed checks.
VALORANT VAN Restriction 5 FAQ
What does VALORANT VAN Restriction 5 mean?
It points to HVCI, also called Memory Integrity, failing to initialize in the security state required by Riot Vanguard. It is a device configuration restriction.
How do I fix VAN Restriction 5?
Check Memory Integrity first, resolve incompatible drivers, verify UEFI and Secure Boot, then review virtualization and NX/XD only when the Vanguard message requires them. Restart after each completed change.
Is VAN Restriction 5 an account ban?
No. Changing the Riot account does not fix the Windows or firmware condition blocking Vanguard.
Where is HVCI in Windows 11?
Open Windows Security, select Device security, open Core isolation details and review the Memory Integrity status.
Can the error happen when Secure Boot and TPM are enabled?
Yes. Incompatible drivers, disabled virtualization, NX/XD configuration or another incomplete dependency can still stop HVCI.
What if Memory Integrity will not turn on?
Use the incompatible driver list shown by Windows. Update the named driver through Windows Update or the official hardware manufacturer, or remove the related unused software through normal Windows tools.
Should I change BIOS settings myself?
Only if you understand the device firmware and have checked its official manual. Incorrect boot or security settings can stop Windows from starting.
Will reinstalling VALORANT fix Restriction 5?
Not when the cause is a disabled or blocked Windows security feature. Fix the requirement named in the Vanguard message first.
Enter the next queue with the account you want.
Choose around region, rank and inventory once Vanguard runs cleanly.
