When you’re faced with a difficult problem with an application, it’s easy to become caught up in the rush to fix it and lose one’s sense of good judgement. In today’s technology age, viruses are so common that, even with anti-virus software, the odds of a given computer being infected at some point are 1 in 9 as opposed to 1 in 1000 a decade ago. As such precautions should be taken when downloading dll files to fix programs especially considering the privileged environment in which they run. They can do a lot of damage. When you access a site that offers dll files for download be careful.

1) Look at the site and judge for yourself if it looks well-put-together.

2) Scan dll files downloaded IMMEDIATELY before unpacking them.

3) Scan the dll file itself again to be on the safe side.

Even then, a dll file may be corrupt but the odds of malware infection are greatly reduced.

PDH.DLL stands for Performance Data Helper Library and it provides functions that are necessary for basic operating system tasks to run correctly. This file has been the subject of various virus hoaxes but it is a legitimate Windows file and should not be tampered with.

Should you find your computer malfunctioning, or even refusing to boot up, you need to take steps to fix this file immediately. The recommended option is to reinstall the latest Windows Service Pack Alternatively you could try to save time and copy the file directly from the CD but this is NOT recommended. After this procedure it might be wise to re-install Microsoft Office in case of file corruption and to run a registry check utility program to fix any remaining errors.

This dll files is not really a system file but rather a file developed by the makers of Nero products to support their software. Many people have encountered errors installing Nero software such as ;

‘This program requires the file advrcntr3.dll, which was not found on this system.’

If this happens to you simply download the file online and ensure that it is legitimate i.e. scan it with anti-virus software and check if the file size is correct. Place it in the system folder and then type “regsvr32 advrcntr3.dll” in the Run command box. Following this, your installation should work normally.

Installing a dll file is very easy and can make the difference to that application that just won’t run even though your PC greatly exceeds the system requirements. Once the dll file is present you simply need to ensure that it’s in the correct system32 folder and then register it as follows.

1) You open the Run command box

2) Type “regsvr32 *offending dll here*” and press Enter

A pop-up box will let you know if it was installed correctly.

DLL files are behind a large percentage of software errors and crashes yet few know what the abbreviation DLL means let alone what or why they are. DLL stands for “Dynamic Link Library” and a dll file is a set of miniature programs or files, usually used by multiple applications that reside in the system folder or the folder from which the application is executed.

Though not a rule, dll files are normally associated with simplifying low-level tasks for applications. For example, d3d8.dll file is Microsoft’s way of simplifying the extremely difficult task of rendering magnificent 3d graphics by providing the generic functions necessary to do so in a simple package.

Another purpose behind them is to save storage space. Certain functions, such as a print function call, are used by multiple programs and for each of these to natively implement the function would be a waste of valuable hard disk space. A dll file provides the function to all the applications that need it without them needing to have the code built-in, thus increasing their size.

On the software development side it makes developing programs much easier with ready-made functions provided by dll files.

In relatively simple words, a dll file is a group of non-independent programs that provide necessary assistance to larger ones.

If dll file errors cause your computer to become unbootable, the standard procedure is to reboot the machine in Safe Mode. During the boot process your computer will likely give you such an option.

Once Windows is loaded in Safe Mode, your first action should be to attempt to fix the dll files by using the System Restore utility. This enables you to reverse some recent registry changes, system file deletions and such provided you had system restore turned on while your computer was working. After this you will need to reboot your machine again to see if it works normally.

Failing this you may need to re-install your operating system from the CD as most of the dll files will be replaced in this way.

Dao350.dll is an essential system file, critical to the proper running of Visual Basic Applications, particularly to those that work with databases. Yet many operating system installations, for various reasons, lack this critical component and, as such, crash when certain software applications are run. For example, while attempting to install a certain sports’ database related software, the computer in question displayed a number of error messages citing seemingly infinite numbers of errors in “data objects” and such.

This difficulty is easily remedied by obtaining the missing DLL file, whether from a friend’s computer, or online or from your relevant Windows CD and placing it in the system folder. Normally this is C:\WINDOWS\system32 but it may vary so do a search for the system32 folder if necessary. After pasting the DLL file in the folder you simply need to register it so that Windows can recognize its presence for use as follows:

1) Click ‘Start’, and then select ‘Run’

2) In the box provided type regsvr32 dao350.dll and press ‘Enter’

A message will notify you of your success and you may then re-launch the complaining application with confidence.

This dll file serves the general purpose of supporting common Microsoft Applications such as Microsoft Internet Explorer and Microsoft SQL Server. It’s absence or corruption usually results in minor error messages when running such software. As with many dll files this is easily resolved by ensuring its presence or acquiring it perhaps online and then placing it in the system folder. Once this is done simply open the Run command box and type “regsvr32 msxml3.dll” and your success should be evident through a pop-up.

This dll file is possibly the most important file to the operating system and the most disastrous if it becomes corrupted. The damage of this file can cause a variety of errors pertaining to, memory, hard disk failures and other serious problems. This damage is commonly caused by well-designed viruses that manage to bypass Windows’ native protection of its critical system files. It may also be cause by bad software installation. If you have just installed new software you should uninstall it immediately and hope everything works fine. If this fails, your best bet is to completely reinstall Windows as this problem is not usually fixed by the stand download and register dll files procedure.

This dll file is essential to the add-on for Outlook Express that handles faxes and it’s absence or corruption may generate unwelcome errors .A common cause of this is mistaken identity. Many anti-virus programs mistake this Windows dll file for malware and delete it. This problem is usually fixed by running a decent Registry Fix utility to replace or repair the corrupt or missing file. Failing this you can find the file via Google online and then download and install it.

If you do not make use of Outlook Express’ fax capabilities simply delete the add-on. The less tampering you have to do with dll files the better.
