Frequently Asked Questions

DLL-Files.com Client

General

  • How do I install the DLL-file I have downloaded from DLL-files.com ?

    Step 1

    • Open the zip-file you downloaded from DLL-files.com .
    • Extract the DLL-file to a location on your computer.

    If you are unsure about how to extract your zip-file we recommend using File Viewer Plus 2. With it you can open your zip-file as well as over 300 other file formats (like video, music, images, pdf etc.) It’s a handy tool to keep around.  

    • After extracting your zip-file, place the extracted DLL-file in the directory of the program that is requesting the file. Make sure to use a 32bit DLL-file for a 32bit program, and a 64bit DLL-file for a 64bit program. Failure to do so will likely result in a 0xc000007b error.

     

    Step 2

    If that does not help your problem, place the file to your system directory.

    By default, this is

    C:\Windows\System (Windows 95/98/Me),

    C:\WINNT\System32 (Windows NT/2000), or

    C:\Windows\System32 (Windows XP, Vista, 7, 8, 8.1, 10).

     

    On a 64bit version of Windows, the default folder for 32bit DLL-files is C:\Windows\SysWOW64\ , and for 64bit dll-files C:\Windows\System32\ .

    Make sure to overwrite any existing files (but make a backup copy of the original file).

     

    Reboot your computer.

     

    Step 3

    If the problem still occurs, try the following to register the DLL-file:

     

    For 32bit DLL-files on a 32bit Windows, and for 64bit DLL-files on a 64bit Windows:

    1. Open an elevated command prompt.
    • To do this, click Start, click All Programs, click Accessories, right-click "Command Prompt", and then click Run as administrator.
    • In Windows 8/10, go to the Start screen. Start typing cmd and Windows will find "Command Prompt". Right click "Command Prompt" and choose "Run as administrator".
    • If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
  • Type regsvr32 "filename".dll and press Enter.
  • Registering 32bit DLL-files on a 64bit Windows:

    1. Open an elevated command prompt, as instructed above.
    2. In the command prompt, start by typing following and press enter:
    • cd c:\windows\syswow64\
  • then type the following and press enter:
    • regsvr32 c:\windows\syswow64\"filename".dll

    Finally, reboot your PC one last time to refresh the memory. That should do it!

     

  • Why do my DLL files suddenly disappear?

    DLL files can be shared between many different programs. If you remove a program using an uninstall utility it might remove all files it installed during the installation process, including DLL files shared with other programs.

    An install or upgrade might have failed, leaving out some needed files.

    This might also happen if you manually copy the files of a program from one location to another, without using the proper setup process.

  • Why do I get DLL errors?

    Because of the way DLL files work, many of them are included by default in any windows installation. So, when you install a program, it assumes that the information it needs to run is already present on your computer. If a particular DLL needed for operation is missing or corrupted that program will no longer work. It will give a DLL error that you see on your screen.

    In most cases, DLL errors appear when programs or files are corrupted by viruses or other malware, or even removed by your anti-virus program after such an infection. Other situations may appear when a file is removed during uninstallation of a program or when removed manually by accident. But it could even be as simple as you trying to run an older program on a new computer, where the old DLL files that the program requires are not included by default in your new Windows installation. The opposite, trying a new program on an older computer is also a possibility for the same reason.

  • What is a DLL?

    DLL stands for Dynamic Link Library, which in short means it’s a library of information, or functions, that can be linked to from different programs that make use of the information in the DLL. It is dynamic in the way that it is a repository with often several hundred functions, and the program linking to it can make use of any of them, or all, as required. The benefit is that programs do not have to include every single function in its own files, instead using the shared DLL, thereby reducing the program size.

    A simplified example; ten different programs all need to show some form of button on your computer screen. Instead of each coming with its own button, they all call the same “showbutton.dll” that already exists on your computer. Since all ten programs use the same file, less space is used on your computer.

  • "filename.DLL could not be found"-error from RunDLL

     

    This is a fairly common error and can be related to your antivirus removing a file perceived as a threat, but not the autostart task or scheduled task to run it:

    The simplest way to get rid of the error, is to stop Windows from attempting to load this file.

    If you are facing a different situation and a different known program is demanding this file (typically referenced in the error message), or if you are uncertain, contact our support by submitting a ticket above and we can give more specialized help.

    How to remove the task attempting to run the missing file;

    1. Download the free program Autoruns by Microsoft.
    2. Run Autoruns (as admin) and find the yellow highlighted Image Paths that ends with the filename in your error message. Usually you can locate those image paths from the tab named "Scheduled Task".

    3. Right click any yellow highlighted row ending with the filename and path from the error message, and choose delete.
    4. Try to find all yellow highlighted Image Paths that ends with the filename and path from the error message from "Everything" tab, delete them.
    5. NOTE: Carefully choose image paths that ends with the filename from the error message only, if you deleted paths that are not highlighted then it might cause some trouble booting your PC.

    6. Reboot Computer
  • 0xc000007b ERROR

    Programname.EXE - Application Error

    The application was unable to start
    correctly (0xc000007b). Click OK to
    close the application.

    There might be multiple reasons as to why you receive an 0xc000007b error when trying to run an application on a Windows computer.

    This error comes from mixing up 32bit environment with 64bit one.
    For example, if a 32bit application tries to load a 64bit DLL-file, it would cause this error.

    Make sure that you have the correct version of the program for your Windows environment.

    Often the 64 and 32 bit versions of a program are the same, but if you get the 0xc000007b error, check your system to make sure which bit version your system is. Check this in the Control Panel - ‘System’ option.

    Look for "System Type" in the window that opens.

    Or find out with this Microsoft guide.

    If this happens after installing a file with the DLL-Files Fixer, this means you've got the wrong version. Go back and install one of the dll versions with the other bit structure.
