The update fixes the specific issues shown on the download page, but it also contains all previously released patches. Some of these address crashing and may eliminate the error altogether.
2. Turn on compatibility mode if you do not have Windows Vista Service Pack 1 or Windows XP Service Pack 3. The game officially supports these two versions of Windows, but will also run with Windows 7 and some earlier versions of the operating system. Right-click the game icon and click 'Properties.' Go to the Compatibility tab and select the check box option 'Run This Program in Compatibility Mode.' Use the drop-down menu to select either Windows XP or Windows Vista.

3. Run Windows Update, and install updates for all other programs necessary to run the game. This includes Adobe Flash Player, Games for Windows Live, Microsoft .NET Framework 3.5 and DirectX. Look for graphic card driver updates at the manufacturer's website -- usually Nvidia, AMD or Intel.
4. Install a genuine, store-bought version of the game. You can find pirated copies of 'Grand Theft Auto IV' all over the Internet, but they still come with a price. They can contain viruses and even bugs not found in an authentic copy. Some errors are introduced intentionally to discourage illegal downloading.

4. Run a separate scan for viruses on your computer. Viruses, like spyware, can cause a 'Runtime Error' message to appear on your screen when you are trying to open a web page with Internet Explorer. Just as in Step 3, you should close IE and then update your anti-virus software before you scan the computer.

1. Remove the last application or hardware installed to determine drivers and system errors. If Windows XP software suddenly engages in an odd behavior not previously experienced, there may be a software or hardware conflict. A certain driver or system file may not be fully compatible with the operating system’s current state, resulting in frequent errors in your system. Write down the error and perform an Internet search on it. If the issue is widely known, there may be an effective solution to fix errors in Windows XP software that can eradicate the source of the problem.
2. Press the “F8” key as your computer is starting up. Select the option “Use the last known configuration that worked” from the Advanced Boot Options screen. This option is used to restore all system settings to the last successful startup session, providing you with a better chance to fix errors in Windows XP. Oftentimes, selecting this option eliminates software-related 'blue screen' errors and other mild installation issues.

3. Select “Safe Mode” to troubleshoot and fix all Windows XP severe problems. Launch Safe Mode by pressing “F8” during startup, and your computer will enter a modified Windows XP session with most networking and performance settings disabled. This is useful in the event that a blue screen error prevents you from successfully accessing Windows XP regularly. Diagnose the issue by accessing the Windows registry, uninstalling previously installed software or making any kind of modification you believe might fix Windows XP. Removing or modifying one setting at a time is best to pin point the exact cause of the problem.
4. Perform a Windows XP System Restore from Safe Mode. If all else fails, launch this handy recovery tool to revert Windows XP to an earlier date when it performed more effectively. This is a convenient way to fix errors in Windows XP software, especially when they have been caused by a program malfunction. Select “Start,” choose “Programs,” click “Accessories,” select “System Tools” and click “System Restore.” Choose the date to which you would like Windows XP to revert to, and allow it several minutes to perform the task.
