What Is Punkbuster

It's a service that servers can choose to use if they want to. It does it's job by scanning the memory of your local machine and is thus required to be running, have access to your computer and be able to update itself by downloading the newest files when this is required.

Punkbuster will install these to your computer:

Simple Solution 5 - Update Your Software

Sometimes security software mistakes Punkbuster for a virus or similar. To avoid this try manually updating all your security software like Windows, antivirus programs, firewalls, security suites, antimalware etc.
After this reboot your computer.


Simple Solution 6 - Give Punkbuster Access
Your antivirus / firewall and other security software might block Punkbuster. You need to explicitly allow Punkbuster through your firewalls and whitelist its services with in your security software.
This will tell you how to let Punkbuster through the Windows Firewall, for your other third party applications you will have to look through help files about how to do it.

  1. On Windows 8.1 navigate to "Control Panel\System and Security\Windows Firewall\Allowed apps".
    On other versions of Windows you will need to find its equivalent.
  2. Click "Allow Another App..." and navigate to "C:\Windows\SysWOW64\" and select first PnkBstrA.exe and then PnkBstrB.exe and set their settings to be allowed through public and private as shown in the picture below.

Simple Solution 7 - Jiggle The Compatibility Settings
Punkbuster should run well on all versions of Windows. That being said certain computer hardware/software setups can mess this up.

First thing you should do is make sure every .exe file used to run the game doesn't run in compatibility mode of any other Windows version. Like this:

  1. Right click .exe file
  2. Click Properties
  3. Click the Compatability tab
  4. Make sure Compatability Mode is not enabled like in this image
    Changing Punkbusters compatibility settings
  5. Keep doing step 1-4 for all relevant .exe files like the game executable, the punkbuster .exe files, gameclients like Steam, Origin etc.

Advanced step (kept in simple solutions to keep things together)

If the above does not work people have reported almost all combinations of compatibility settings and .exe files have helped them. This should not be needed but if things is not working or you are running a beta version of Windows or something weird is happening you might want to run step 1-4 mentioned above but instead of not having compatibility mode enabled you now enable it with another version of Windows than you are running now.


Advanced Solutions

Remember, it's always a good idea to take a backup of your system before messing too much with it! Ye, be warned.

Advanced/Rare Solution 1 - Clean Boot
Check if a third party program is interfering by trying to play after a clean boot where the two Punkbuster services are still running. A guide on how to do so is located here: http://help.ea.com/en/article/how-to-clean-boot-your-pc/

Pictures on how to do this can be found here: http://support.microsoft.com/kb/929135


Advanced/Rare Solution 2 - Check Hard Drive For Errors And Corrupted Files

All files can become damaged. This is just the nature of hard drives. If this affects the Punkbuster files this can cause errors and it's therefore a good idea to scan your hard drive. Do this for all hard drives that has Windows, Punkbuster and the game installed.

  1. Go to "This PC" in Windows and right click the hard drive and click "properties"
    Rightclick harddrive
  2. Go to "Tools" and and press "Check"
    tools then scan drive
  3. Click "Scan Drive" and let it scan for errors.
  4. If it finds errors let the program fix them
    (If there are errors it could mean nothing, but it can also suggest that it might be time to format your computer and/or replace the hard drive)
  5. Reboot your computer
  6. Run the scan again
  7. Keep repeating step 3-5 until no errors are found.


Advanced/Rare Solution 3 - Reinstall DirectX

Should some program have modified DirectX you need to remove all traces of that and reinstall DirectX.

You can find the DirectX installer here: http://www.microsoft.com/en-us/download/details.aspx?id=35.
It's also typically located in your game folder in the "__Installer\directx" folder.


Advanced/Rare Solution 4 - Disable Shader Injectors

Uninstall "SweetFX" and whatever else can modify what is shown on the screen.


Advanced/Rare Solution 5 - Check Windows for Errors

A broken Windows Installation can cause all kinds of trouble. To scan your Windows installation for errors open a command prompt with admin rights and run the command: "sfc /scannow". A more detailed guide on how to do this can be found here:

sfc /scannow


Advanced/Rare Solution 6 - Restart Your Network Hardware

Like your computer, network hardware will get sluggish and makes mistakes if it has not been rebooted in a long time. Usually this takes weeks or months to happen but some routers or modems need to be rebooted more frequently. Take the time to unplug your modem and router for 30 minutes. Then reboot your modem first and let it load before starting your router. It is also a good idea to reboot your machine after doing this.


Advanced/Rare Solution 7 - Improve Punkbuster Permissions Beyond Standard

  1. Right click your game folder, make sure the "Read Only" setting is not ticked off.
  2. Enter "services.msc". (picture can be found in Simple Solutions 4)
  3. Find "PnkBstrA" and "PnkbStrB".
  4. Right click both and select "properties", click the "log on" tab and check the box that says "allow services to interact with desktop".
