You're suppose to run iw4mp.EXE, not .DAT

lol, when you launch iw4mp.exe it does it checkups and then launches the iw4mp.DAT

Please before you create new thread, try all those solutions.


Reinstall Microsoft .Net 3.5 Framework and Microsoft Visual C++ 2008 Redistributable
get both from viewtopic.php?f=3&t=24
On Vista/7 you need to enable .Net Framework in Windows Features: https://gyazo.com/3c96238ae0c7320357eb38b4b49fc8a8.png
Note: Windows 7 does not require .Net Framework 3.5 setup.

Remove file caches.xml and start the game to update and verify game files.

Make sure game is located in Program Files folder, having it on Desktop can cause problems.
Run game as Administrator on Vista/7.

Some security software can cause crash:
Make sure your are using latest version of your Anti-Virus software.
Make sure you have up-to-date detection list.
Add iw4mp.exe and iw4mp.dat and steam_api.dll to Antivirus exception list.
Follow this guide: alterIWnet • View topic - Add Exceptions to Anti-Virus

if you use ZoneAlarm or Comodo, follow viewtopic.php?f=30&t=20604
If your Anti-virus has GamingMode ( or Gaming profile), activate it (Kaspersky, BitDefender).
Note for Avast! users - viewtopic.php?f=30&t=48149

Remove system hooks (yes it is safe):

If you have a 32bit computer, download and run https://tdtgaming.com.au/files/AppInit_DLLs_x86.reg
If you have a 64bit computer, download and run https://tdtgaming.com.au/files/AppInit_DLLs_x64.reg

If those don't work (you get an error while applying the fixes), try the legacy way:

Spoiler: Toggle
Open regedit (Start -> Run "regedit")

Find this directory:

Code: Select all
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows


Find key APPINIT_DLLS, and make it empty.

If you have 64-bit system, repeat it with this directory:

Code: Select all
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ Windows NT\CurrentVersion\Windows


Find key APPINIT_DLLS, and make it empty.



Use CCleaner to clean your registry.

Check this screenshot, if you do not understand.

Restart your computer.



This may be caused by a faulty sound card configuration, especially if you changed from a PCI card to an onboard one.

Open regedit (Start -> Run "regedit")

Find this directory:

Code: Select all
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32


Delete all duplicates for "aux" "midi" and "wave" keys, ie. their duplicates with numbers (aux1, aux2, etc.).

If you have 64-bit system, repeat it with this directory:

Code: Select all
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ Windows NT\CurrentVersion\Drivers32



Restart your computer.



Use SFC Scannow to Repair Protected Windows Files.

Description of Windows XP and Windows Server 2003 System File Checker (Sfc.exe)


Make sure you have latest Service Pack for your Operating System.

If is your game still not working, please create new topic in Tech Support section with your profiling info: alterIWnet • View topic - Profiling
