When you receive the error, you should read this article and learn to fix it if files on your computer are important to you. The most precious thing is data stored on computer and some Windows error may lead to data directly or indirectly. This article covers solutions to a couple of error cases, and you can click subtitles below to read detailed information:

Access violation error 0xC0000005

Error description

The 0xC0000005 Access Violation error is quite common among all versions of Windows systems and it is fairly broad as it involves a batch of issues. As a rule, system returns this error code when you run a program that attempts to access the location not assigned for its use. When the error message is closed, usually the software will be closed as well. The error means the software want to use system memory improperly. The error code 0xC0000005 also happens to other situations with different messages such as when you attempt to install system, perform certain function, launch system built-in tools, etc. You may meet one of the following messages when the error occurs:

An application error has occurred and an application error log is being generated. Exception: access violation (0xC0000005), Address "The application failed to initialize properly (0xC0000005). Click OK to terminate the application"

The "Stop 0x0000008E (0xC0000005 ...) " combination on the blue screen


Operating system is multi-tasking and complicated to provide better user experience. System has to distribute memory to fulfill tasks, making different processes have allocated memory and preventing virus. When a program attempts to access memory which has been distributed to another process and is not available for this one, you'll receive the error and the software will be terminated.

Causes of the error can be various, some common reasons behind this error are: registry issue, faulty RAM, DEP function, corrupted drivers, virus infection, incorrect system security update, etc. In many cases, it's difficult to tell the actual cause and you may need to try different solutions to get rid of the error. Not long ago, Symantec Antivirus software was a well-known cause to 0xC0000005, which can be fixed by simply updating the software. Besides, this error code can be outcome of using some third-party applications, and you should check their website or technical support to see whether this problem is noticed.

Causes are somewhat complex, but solutions seem simple. The following section gives several common ways of fixing the issue.


It's hard to clearly define the error on account that there are so many causes and different circumstances, thus its solutions are equally many. You may have to try many of these solutions before you find the one working for you.

Method 1: Scan virus

If your computer infects malware or virus, 0xC0000005 error is reported to prevent executions performed by malicious programs. Virus or malware infection is one of the most frequent common and starting a virus scan should be the first attempt. If there is malware or virus on your PC, the error code you get is a signal of it. The correct and first response to that is running a full virus scan for computer system and personal data as soon as possible. If you already have installed antivirus software, then update it to the latest version and carry out virus scanning.

Method 2: Repair registry

In some situations, the error code is caused by poor system maintenance and corrupted registry entries. Registry corruption appears due to software installation or uninstallation, for example users install new applications over old ones without deleting or uninstall them properly. System registry is usually deemed as SPOF (single point of failure) by many Windows users, which indicates that operating system is tied to registry and registry corruption may lead to system abnormal functions.

In order to eliminate the error, you have to check registry entries and delete all redundant and invalid entries, but that'll be a complex process to many users who are not computer experts. One improper operation may turn computer into inoperable, such as deletion of wrong entry by accident. If you are not a computer guru, you can try some third-party software which is able to scan and repair corrupted registry automatically instead of repairing registry manually. Quite a few such programs are available on the Internet, and most of them work equally well.

Method 3: Disable DEP (Data Execution Prevention)

Data execution prevention was initially introduced by Microsoft and used on Windows XP Service Pack 2 and later versions. It is a set of security features designed for preventing code execution from non-executable memory segments. It checks memory in order to protect computer against virus.

DEP has been enabled for both hardware and software components since Windows XP SP2. However, some programs are still unable to be fully compatible with it. Some applications adopt a technique, usually called dynamic code generation, which doesn't tag these codes with an execute permission. As a result, this conflict gives rise to the problem. Besides, if software is developed without SafeSEH, it tends to cause 0xC0000005 error when DEP is enabled on the computer.

If you encounter the error code because of DEP, you can contact the developer of the software causing the issue and ask whether they have a solution. Alternatively, you can disable DEP for the software in question and this can be done through following steps:

Step 1
Log in computer with Administrator account to make sure you have fully administrative rights.

Step 2
If your computer is running Windows XP, click "Start" button and select "Run". Windows 7 user can press Windows and R keys. Type sysdm.cpl in Run box and click OK.

Step 3
You can see System Prosperities window from which you need to click Advanced tab and then Settings.

Step 4
The "Performance Options" window will pop up and please click "Data Execution Protection" tab. Select the option "Turn on DEP for all programs and services except those I select" and click "Add" button.

Step 5
Browse files from the Open applet and find the exe files of the software which causes the error code. Select it and click "Open" button.

Step 6
Click "Apply" and "OK" to make changes take effect.

Method 4: Remove bad RAM memory

A lot of times, a bad or incompatible RAM (Random Access Memory) brings about the issue. For instance, you've just added a new memory to your computer aiming to improve performance; however, you start to receive error code 0xC0000005 since then. You can get rid of the problem by simply removing the memory and restarting computer to check whether the error has disappeared. If that works, get a refund of the memory or replace it with one that is fully compatible with your computer. Before taking away RAM memory, you should turn off computer and remove all cables such as power, network, etc. If your PC is laptop, remove battery after shutting down computer.

Method 5: Update Internet Explorer 6.0

The error code may appear in Microsoft Internet Explorer 6.0 when you attempt to access an HTML file or web page. Meanwhile, the IE appears to stop responding when the error occurs. This problem appears especially when the HTML document or web page Internet Explorer 6.0 tries to open includes SPAN tags which were incorrectly closed. If the SPAN tag is not closed correctly with tag, the access violation will happen.

With regard to solutions, Internet Explorer is outdated and current Windows 10 introduces Edge. You can install the later version of Internet Explorer such as Explorer 10 or use other free browsers such as Google Chrome, Mozilla Firefox, etc.

The application was unable to start correctly (0xc0000005)

Error description

In general, the error appears when you try to run a program on your computer and receive the following message:

"The application was unable to start correctly (0xc0000005). Click OK to close the application."

You might go crazy because of the error message, as it may happen to any software installed on your PC such as iTunes, Windows media player, Google Chrome, VLC, MAX Payne, etc. In many cases, the reinstallation of the application can't fix the error.
