I have an 11th gen Intel processor and pavlov does not start for me. When I launch it Anti-cheat shows up then the game closes.

Does Pavlov Start then immediately end on Steam? Try this fix: Intel Gen 11 fix


Game worked for me after update, but recently (14/10/21) it crashes on start

October 14th, 2021: If you cannot launch the game please check and unsubscribe from all of these maps: https://steamcommunity.com/id/Lamson555/myworkshopfiles/?appid=555160


Update 26 Broke for me I crash at start with the Pavlov Crash reporter/I'm having strange game behavior/I'm getting strange game performance

First Delete your Pavlov folder in: %LocalAppdata%

Locate your local appdata folder on your windows installation: %localappdata%/Pavlov/

1. Press start 2. Type "%localappdata%" without quotes and press enter 3. Locate Pavlov folder and delete it.


I'm getting an error saying the procedure entry point could not be located in the Dynamic Link Libary (v8_libplatform.dll)

Find your pavlov game installation folder and locate this directory typically located at: SteamLibrary\steamapps\common\PavlovVR\Pavlov\Plugins

Find the Runtime folder and back it up and delete it. You can either zip the contents or move it to another directory. Restart Pavlov.'


I can't play community maps| unable to move and see players crouched with everything frozen for about 30 seconds and then get disconnected with an "authentication timeout"

Change your startup map to the main menu, not shooting range.


Steam is stuck in an update loop

Please make sure you have a lot of free space on your installation drive to let steam unpack and verify the update. You can also try restarting your computer. If you have to free up space, a restart is required because Steam is having trouble recognizing freed up space.


Unable to play online, offline works fine.

Check the windows firewall to make sure Pavlov VR is allowed. Check any other 3rd party antivirus software or firewalls that may be blocking Pavlov from connection to the internet.


Vibrations on controllers are causes tracking lag (Rift/Rift S)

Try unplugging and plugging in the USB cable for the headset into a different port.

With the exception of your mouse and keyboard, disable or unplug any USB devices that may be active such as a webcam or microphone.

Tip: The Oculus Rift uses a lot of USB bandwidth and can cause issues with tracking when haptics are triggered. Some USB ports on select motherboards are not up to the proper USB 3 spec.


Error message saying need to install 2015 or 2019 runtime version

Try running vrmonitor.exe directly.

two files may be missing: msvcp140.dll & vcruntime140.dll

This may have something to do with a Microsoft update of its "Microsoft Visual C++ Redistributable for Visual Studio 2019" package

download the version of VC_redist.x64.exe from this page: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

if you have this issue in a 32-bit system, you'd want to try the 32-bit version.


LowLevelFatalError crash message on launch

Does your error contain a UGC number? It may look something like this:

.../.../pavlov/content/custommap/UGC1234567890/definition.uasset

This is a workshop map that is broken and you will need to unsubscribe from it. You can find out the map that is causing this by going to the link on the workshop with the UGC number. Paste the url into your browser https://steamcommunity.com/sharedfiles/filedetails/?id=

After ?id= in the link add the UGC number in your error without the UGC like so https://steamcommunity.com/sharedfiles/filedetails/?id=1234567890

  • This is not a valid UGC number and only used as an example

Please notify and report this map to developers so they can mark the map as incompatible.

Many crashes are related to Steam Phonon audio. Please make sure your audio drivers for your motherboard chipset are up to date, try disabling any software that may be affecting audio in any way.

If you have a very old steam profile picture try changing it to current steam dimensions and standards without transparency. This has caused issues for some players.

Known software that can cause conflicts: Nahimic 3, 3rd party firewalls/antivirus such as Avast. Anything that tampers with hardware on your computer like CPU or GPU management software.

Make sure you are on stable, non-beta branches of your respective software. If you are on Oculus or have Oculus software installed for Revive, make sure you opt-out of any beta programs such as the Public Test Channel. If you are on SteamVR hardware make sure you are not using a SteamVR beta branch.

To opt-out of Oculus PTC: Oculus Software > Settings > Beta-Version > Public Test Channel > Disable

Make sure your Oculus software is up to date with the correct version on main branch.

To opt-out of SteamVR Beta: Find SteamVR in your library under the “Tools” section. Go into Properties > Betas > None - Opt out of all beta programs

If the above does not work please proceed try cleaning your Pavlov VR installation if you have been able to get Pavlov VR to launch in the past.
