Access Violation problems are generally a result of improper memory usage by the computer through different computer applications. This can actually be compared to the locking of a gate. Files become inaccessible and can not be opened without the fixing up of the access violation error. Access Violation is essentially very common with software malfunction which again usually happens due to poorly written software. Not only with Windows but also with UNIX and other operating systems that one may face the problem of access violation, although it must be said, Windows is a prime offender!

Any attempt to access the source files is nullified by the security layer that is created with the overburdening of the memory module.

Many a times the permission error i.e. access violation error can be resolved by entering a command prompt to change the file attributes. For e.g. a file can be made readable or writable without opening the file but only by the use of a command. A read-only file can not be written upon directly prompting an access violation and therefore the attributes need to be changed. The DOS command prompt is usually quite simple : ATTRIB [+R | -R] [+A|-A] [+H | -H] [[drive:][path]file] [/S] where R means Read-Only; A means Archive attribute; S is System File and H is Hidden File attribute.

In addition to these solutions other kind of access violations need to be dealt with in a different way. If the access violation is caused due to a C++ 2005 application; it may be due to an invalid code generated by the C++ compiler. A corrupted v-table is contained by the application due to the error resulting in an access violation. This can be resolved by a Hotfix available through Microsoft.

A Data Execution Prevention [DEP] was introduced in Windows XP service pack 2. It performs additional checks on memory and thus helps protect the computer against adwares/malwares and the malicious codes generated through them. Applications that violate DEP get the message for access violation. It is always possible to turn off the DEP but this would have to be the last step.

For games and other windows associated applications the access violation is generally resolved by increasing the memory module. Other Windows related access violations can be dealt with by optimization of the computer performance through readily available softwares. The softwares are able to restore processes that were causing problems with the RAM. Also, junk file cleanups and ending unused processes can avoid receiving an access violation.

Windows XP should be equipped to have at least Service Pack 2. It has a number of hotfixes that help in the debugging of related softwares and to avoid access violations. Access violation problems are not incurable. Mostly all kinds of access violations, trough device drivers, RAM, poor written softwares etc can be resolved if proper measures are taken. As a precaution, one can increase the RAM in a computer which performs tedious tasks. The last resort to solve the access violation problems is to call the computer service person or the vendor.

In common computer parlance any memory access violation is termed as an access violation problem or an access violation error. This can happen mainly due to illegal violations that cause the abnormal functioning of the software in question.

A faulty RAM may be at the root of the matter. Many computer users often consider their RAM to perform tasks that are either not supported with the memory allotted or might have internal problems with the memory module.

Device drivers are actually a bridge between higher level computer programs and the devices present inside a computer. It is basically a translator between the devices and the applications or the operating system. Device drivers are an important part for the proper working of the applications. There may be a case where the device working may be in danger due to installation of improper drivers for it. Due to this there may be an access violation.

Softwares are sometimes poorly written or can not be updated properly. These poorly written softwares or bugs as they are generally called can also be a causal agent of the problem. Also, malware and adware are sometimes installed unknowingly over the internet which leads to an overburdening of the memory module and may cause errors in the programs resulting in the access violations. Normally we see that certain games that are installed may have incorrect setup files which after installation show the above error.

Access violation is a reference to a corruption in the terminal services information. Tsprof.exe, Mmc.exe,Usrmgr.exe etc are examples of Terminal Services administrative utility. When these files are executed, there may be an access violation error and the utility might quit unexpectedly. Again we will see that access violation errors are not bound to the above examples only. There are various programs that use the API functions of WTSSetUserConfig or the WTSQueryUserConfig. This is done for setting or retrieval of any user information. When these programs are run, the utility may show an access violation error and might shut itself off while it still manages certain other accounts. This error is also termed as an 0xC0000005 error.

Microsoft Windows update is another tricky venture which might lead to the access violation error. When one tries to update from Microsoft Update or Windows update, the system might go to a standby position and shows the access violation. When one tries to make a Remote Desktop connection, further trying to log on to it with a certain account, the connection may suddenly close and on restart shows the access violation error.

Access violation is normal with the scans for Microsoft updates using the Windows installer. Svchost.exe, which relates itself with the Automatic Updates Service, may receive an access violation error depending on its method of carrying out a Windows Update. This Windows Update then leads to a memory leak which lengthens the update scan.

This often leads to the malfunction of IE 6, unresponsive to web pages. Access violations are common in computer vocabulary which may result in memory locks.

An Access Violation error is the abbreviated term for what’s known as a segmentation fault. It is a problem that occurs when a program, or a piece of software, tries to access memory that it doesn’t have permission to use.

It’s the computer equivalent of walking in to a locked door, you could say. The files that you want are protected by a security layer, or are simply locked and inaccessible from your current environment.

Access Violation errors are also a very common trait of software that is configured incorrectly. While UNIX machines will receive a SIGSEGV signal about the invalid memory, users on Microsoft Windows operating systems will be presented with the STATUS_ACCESS_VIOLATION exception, better known as an Access Violation.

If, for example, you have a hardware device which is recently installed, and software which is used by other programs, it’s possible that you’ll receive an Access Violation when trying to use the new hardware device, if its drivers are being used by another source. These sort of collisions will often result in Access Violations where a piece of software is in demand from two or more pieces of hardware, and it can only feed one at a time.

The memory is thus locked, and any attempt to access the important source files will be blocked out. The Access Violation error is returned, and you, the end user- will be left to scratch your head.

You may have also received an Access Violation exception when attempting to access a typical file or folder that you wouldn’t expect to be involved with any system processes or crucial drivers. In most cases, this is down to the attribute of the file.

If you try to write to a file which is designated as Read-Only, you will be attempting to breach the security permissions of that particular file. This is blocked out by the Access Violation exception. But the good news is, such errors are easy to fix.

To resolve a permission error, we need to enter the Command Prompt and make a change to the attributes of the file. If you can’t open it, we need to make it readable. If you can’t write to it, we need to make it writeable. And so forth.

The Dos command for making changes to the attribute of a file is shown below:

ATTRIB [+R | -R] [+A | -A] [+S | -S] [+H | -H] [[drive:][path]file] [/S]

If this is no more than random gibberish to you, don’t worry. It’s quite simple when broken down.

The plus sign is used to add attributes, and the minus sign takes them away.

R is the READ-ONLY attribute.
A is the ARCHIVE attribute.
S is the SYSTEM FILE attribute.
H is the HIDDEN FILE attribute.

Obviously, if you have a file which is Read-Only, you are not going to be able to make changes or edit the contents. This is probably the number one cause of Access Violation errors.

To get rid of them, you simply need to apply the correct attribute formation so that the file is accessible to your needs.
