When you try to start any of the games listed in the "Applies To" section, you may receive an error message that resembles the following:
A debugger has been detected: unload the debugger and try again
This issue may occur if one or more of the following conditions are true:
There are programs (such as an antivirus program or debugging software) that run in the background and that interfere with the game startup process.
Your sound card or sound card drivers are outdated.
The Creative Audigy sound card is installed in your computer. This sound card may conflict with the game startup process.
To resolve this issue, use the following methods in the order that they appear.
Note Method 4 and Method 5 assume that you have the Creative Audigy sound card installed.
Method 1: Rename the Amdfix.sys file
Click Start, and then click Search.
In the All or Part of the File Name box, type amdfix.sys.
Click Search Now.
In the search results list, right-click Amdfix.sys, click rename, and then rename the file as Amdfix.sys.old.
Restart your computer.
If this does not resolve the issue, go to Method 2.
Method 2: Restart the computer by using a clean boot procedure
When you start Microsoft Windows, typically there are a number of programs that start automatically and run in the background that may interfere with the game. These programs may include antivirus and system utility programs. When you perform a clean boot, you prevent these programs from starting automatically. You must be logged on as an administrator or a member of the Administrators group to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
To restart your computer by using a clean boot procedure, follow these steps when you are using Windows XP.
Note You may experience a temporary loss of some services functionality when you follow these steps. Restoring the settings restores the functionality, but may result in the return of the original error message or behavior.
Click Start, click Run, type msconfig in the Open box, and then click OK.
On the General tab, click Selective Startup.
Under Selective Startup, click to clear the following check boxes:
Process SYSTEM.INI File
Process WIN.INI File
Load Startup Items
On the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.
Click OK, and then click Restart.
