More ways to find an error code
We’ve listed the system error codes in this section, organized by number. If you need more help tracking down a specific error, here are some more recommendations:
- Use the Microsoft Error Lookup Tool.
- Install the Debugging Tools for Windows, load a memory dump file, and then run the !err command.
- Search the Microsoft Protocols site for the raw text or error code. For more information, see [MS-ERREF]: Windows Error Codes.
Third party error codes
Other error codes may be generated by third party services or apps (for example, Error Code: -118 may be displayed by the Steam game service) and in those situations you would contact the third party’s support line.
System Error Codes
System Error Codes are very broad: each one can occur in one of many hundreds of locations in the system. Consequently, the descriptions of these codes cannot be very specific. Use of these codes requires some amount of investigation and analysis. You need to note both the programmatic and the runtime context in which these errors occur.
Because these codes are defined in WinError.h for anyone to use, sometimes the codes are returned by non-system software. And sometimes the code is returned by a function deep in the stack and far removed from code that is handling the error.
The following topics provide lists of system error codes. These values are defined in the WinError.h header file.

| Summary: |
| When hardware or software crashes with a fatal exception it reports an exception code. These assist in identifying the type of error that occurred. For any CitectSCADA exceptions that write to the bin\debug.log file you would normally see the exception C0000005. After you upgrade your computer to Windows XP (or re-install XP), you may receive the following STOP error message on a blue screen : Note: The four parameters in this error message may vary depending on the cause of the STOP error. Memory Allocated as PAGE_GUARD by VirtualAlloc( ) has been accessed. The thread tried to read or write data that is misaligned on hardware that does not provide alignment. For example, 16-bit values must be aligned on 2-byte boundaries; 32-bit values on 4-byte boundaries, and so on. SetErrorMode( ) may be used to modify the system’s behaviour and auto-correct such misalignment, albeit at significantly impaired performance. A breakpoint was encountered. You can actually skip to the next instruction now if you’re devious with Exception filters. The OS jumps to a breakpoint when HeapFree( ) shows guard byte corruption or other trouble. A trace trap or other single-instruction mechanism signalled that one instruction has been executed. An attempted read or write to/from an address to which that process isn’t allowed access. [Or from HeapAlloc() with invalid parameters/corrupt heap] The thread tried to read from or write to a virtual address for which it does not have the appropriate access. Usually this indicates a pointer error of some sort. This error is an access violation, which means some piece of software tried to access something (could be hardware, software, memory address or a file) that for some reason it was not entitled to do. The offending software did not adequately handle the exception so the operating system took over and terminated it with the 0xc0000005 error. The thread tried to access a page that was not present, and the system was unable to load the page. –i.e. the program or memory mapped file couldn’t be paged in because it isn’t accessible any more. Device drivers can return this exception if something went wrong with the read (i.e. hardware problems). For example, this exception might occur if a network connection is lost while running a program over the network. The API call was passed a handle to a kernel object which was invalid -usually because that handle has already been closed. Use the repair procedures for XP by booting to the XP O/S disk. Go through until you get to the repair choice. ( hit R). Try repairing the OS first. If this does not work or you are not comfortable using recovery console, the only other choice is to re-install the OS. The way to correct this is by reinstalling Windows XP. You can do a repair option and all your data and setting will remain intact. You can find instructions on doing a repair install here Called by HeapAlloc( ) if you specify HEAP_GENERATE_EXCEPTIONS and there is no memory or heap corruption.. The thread tried to execute an invalid instruction -such as MMX opcodes on a non MMX system. Branching to an invalid location can cause this -something stack corruption often causes. The exception filter returned EXCEPTION_CONTINUE_EXCEPTION when the exception raised isn’t re- startable . The thread tried to continue execution after a non-continuable exception occurred. An exception handler returned an invalid disposition to the exception dispatcher. Programmers using a high-level language such as C should never encounter this exception. The thread tried to access an array element that is out of bounds, and the underlying hardware supports bounds checking. x86 family processors do not generate this exception. One of the operands in a floating-point operation is denormal. A denormal value is one that is too small to represent as a standard floating-point value. The thread tried to divide a floating-point value by zero. The accuracy of the last floating point operation is worse than usual as it is impossible to represent in the float accurately, Any other floating-point exception. The result was too big to represent A floating point stack overflowed or underflow. This related to the baroque design of the floating point unit. The result was too small to represent Attempted division by zero The last integer operation caused an overflow The result of an integer operation caused a carry out of the most significant bit of the result. The instruction is not allowed in the current ring (inport, outport & control register manipulation usually). No fix, other than ‘don’t do that’ The thread attempted to execute an instruction whose operation is not allowed in the current machine mode. Stack overflow. Can occur during errant recursion, or when a function creates a particularly large array on the stack. 1.

Lets the debugger know the user hit Ctrl-C. Seemingly for console apps only. System Error Codes (0-499)This information is intended for developers debugging system errors. For other errors, such as issues with Windows Update, there is a list of resources on the Error codes page. The following list describes system error codes (errors 0 to 499).
