How to Repair oacat.exe Not Found?

Take MSHTML.DLL as Example:

You may know that MSHTML.DLL file is heavily involved with the Microsoft Internet Explorer Web browser which could read and display HTML Web pages. On the other hand, you may not know that MSHTML.DLL file can cause the browser to quit unexpectedly while rendering HTML pages. It is the concrete process which the user might take to restore browser functionally.

  • Step 1. Reset Internet Explorer settings by opening the program, clicking the "Tools" menu and hitting "Internet Options." Hit the "Advanced" tab and then click "Reset" in the "Reset Internet Explorer Settings" window to confirm.
  • Step 2. Download and install the latest version of Internet Explorer from the Microsoft website. If you're running an outdated version of the browser, upgrading may solve the the MSHTML.DLL error by replacing the file. While finished installing, Reboot your PC, then open the browser and navigate to an HTML page to test.
  • Step 3. Install the latest service pack upgrade for your version of the Windows operating system. Go to the Microsoft Update website and select "Express Install." Choose to install the latest updates for the PC, then restart.
  • Step 4. Run the System File Checker program. This built-in utility checks important system files and automatically replaces missing or corrupted files. Click\Hit the "Start" menu, then select "Run." In the text area, type "sfc /scannow" and press the "Enter" key. If any files are found to be missing or corrupted, you'll need to insert your Windows disc into your optical drive so the files could be replaced. Restart your PC once the program has ended the check.
  • Step 5. Reset the TCP/IP protocol settings on your PC. Hit the "Start" menu and select "Run." Type in "cmd" to open the command prompt window. Type in "netsh int ip reset resetlog.txt" and press the "Enter" key. It will rewrite two registry entries that are used by the TCP/IP Internet protocol, which may fix the DLL error. Reboot the computer.
  • Step 6. Download and install a registry cleaner that checks the Windows registry for errors and fixes or deletes corrupted entries. Run the registry cleaner to check for errors, opting to repair any that are detected, and then Reboot the PC.
  • Step 7. Test the result of any or all of these steps by opening Internet Explorer and browsing to any Web page with the file extension ".htm" or ".html". If the program renders the pages without error, the MSHTML.DLL file has been successfully repaired or replaced.

How to Registry Dll in Windows Vista Manually?

Almost all dll files on your computer are designed to be self-registering. They have information which must be stored on the Windows registry in order for those files to be used.

It is also possible on Windows Vista to register DLL and executable files manually.
  • Step 1. Know the path and file names of the files you wish to register.
  • Step 2. Hit "Run" from the Start menu.
  • Step 3. Type the following into the field provided: regsvr32 "[path]\NameOfFile.extension". [path] is the directory where the file is located. For example: C:\ The extension will be .dll
  • Step 4. Look for the dialog box that says "DLL Register Server in C:\Program Files/Common Files/Microsoft Shared/MSI Tools/mergemod.dll succeeded." Click "OK." Your file is successfully registered.
  • Step 5. Type "[path]\NameOfFile.exe" /REGSERVER" to register an executable file.
  • Step 6. Launch the program manually if it does not launch automatically, in order to check and see if the registration was successful. Remember that without certain files attached to the registry, the program will not run successfully on Windows Vista.


How to Kill a DLL File?

People may not know that A DLL file contains procedural instructions, resources and assignment through library linking for software applications.
Next, I will take different types of OS as example:
Windows Vista/7:
  • Step 1. Hit "Start" and then on the "All Programs" link.
  • Step 2. Navigate to the "Accessories" folder.
  • Step 3. Right-click on the "Command Prompt" icon and choose "Run as Administrator" from the right-click menu.
  • Step 4. Type "regsvr32 /u file.dll"
Please Pay Attention: Replace "File" with the actual filename of the DLL.
  • Step 5. Push "Enter" to execute the command. Click the "OK" button on the pop-up that affirms the command was successful.
Windows XP:
  • Step 1. Hit on "Start" and go to "Run."
  • Step 2. Type CMD in the run box and press "Enter."
  • Step 3. Type "regsvr32 /u file.dll"
Note: Replace "File" with the actual filename of the DLL.
  • Step 4. Press "Enter" to execute the command. Hit the "OK" button on the pop-up which confirms the command was satisfactory.

Here are some Tips For You:

Tip 1. When you execute the command into the command prompt, the .dll cannot include any spaces or it would fail to execute.

Tip 2. Know the correct entry point of your .dll file before attempting to run it through Rundll32.
Tip 3. Use the regsvr32 /u command to unregister the DLLs.
Tip 4. Always create a system restore point before changing or deleting DLL files, as deleting the wrong file can have dire consequences on how the system runs.
Tip 5. You may not know that sometimes these problems are caused by the websites you are visiting and have nothing to do with your registry. Places like Myspace, Facebook and most social networks have these problems occasionally.

What Can Cause Dll Not Found?

Sometimes, you may receive an error message stating "Windows could not find the filename.dll" or "A required .DLL was not found" or something similar. It means that your PC is missing a dynamic link library (DLL) file or a required DLL occurs some errors.

An error message stating that a particular DLL is "missing" could be caused by a few things. A program that was recently uninstalled removed a DLL that was required by another program, a program which was recently installed overwrote a DLL, a bad installation of a program corrupted a DLL, a malicious program such as a computer virus removed a DLL or hardware problems like a bad hard drive is leading to the error messages.

How to Restore Dll Files?

Take Msvcr71.dll as example, it will tell you how to restore dll files.
Msvcr71.dll is a dynamic linked library included in every Windows computer, and used by many programs developed with Microsoft Visual C++.
Betweentimes, you'll likely receive error messages along the lines of "The program failed to initialize as msvcr71.dll file was not located. Re-install the program to correct the question," or "Msvcr71.dll Not Found."
Do not worry about it, you could do as follows:
  • Step 1. Open your Web browser and go to any DLL download site's page for msvcr71.dll. (See Resources for links.) Hit on the link labeled "Download msvcr71.dll," or something similar. If you are using dll-files.com, ignore the warning regarding advanced computer skills needed---this is slightly a ploy to get you to purchase their auto-installation package. For that site, click the "Download" button and then the link in the window that pops up, to receive the file.
  • Step 2. Double-click on the downloaded ZIP file to open it. Right-click on the DLL in the file browser that opens and choose "Copy."
  • Step 3. Browse to your computer's system folder. It is C:\Windows\System32 on most versions, and C:\Windows\SysWOW64 on 64-bit operating systems. Paste the copied DLL into this folder, so that Windows can find it next time it's needed. If the site you use gives you the DLL in uncompressed form, the way dlldump.com does, simply save it here instead.
  • Step 4. Restart your PC.
