AI-assisted overview

Overview

The Telerik.Web.UI.dll is a Dynamic Link Library (DLL) file provided by Telerik, a company known for creating a wide range of UI controls and widgets for .NET web applications. This particular DLL is part of Telerik's UI for ASP.NET AJAX suite, a set of over 100 customizable UI controls that allow developers to build robust, interactive, and visually appealing web applications without having to write extensive amounts of code.

This library is rich in features, offering controls ranging from simple input controls like buttons and text boxes to more complex components such as grids, charts, and schedulers. All controls come with a myriad of customization options and themes. They are also built to be fast and to comply with various web standards, ensuring a consistent look and feel across different browsers and platforms. The Telerik.Web.UI.dll library encapsulates a significant portion of the functionalities offered by the Telerik UI for ASP.NET AJAX suite, and it is usually referenced in the projects that use these controls.

Being an essential component in projects that utilize Telerik's web UI controls, this DLL should be appropriately licensed, installed, and referenced within your ASP.NET project for the controls to function correctly. It also generally requires that you have the correct version of the .NET Framework installed on your system or server where the application runs. Telerik often provides comprehensive documentation and community support, making it easier for developers to implement and troubleshoot issues related to these controls. Understanding the role of Telerik.Web.UI.dll is crucial for developers working on projects that aim to offer sophisticated and user-friendly interfaces in web applications.

Fixes and Solutions

The first step in resolving DLL errors is to completely uninstall the affected software and reinstall its latest version. We know this does not always solve the problem, which is why DLLme exists. If reinstalling the application does not help, or if you are unsure which app is causing the error, follow the steps below. These are the most common solutions for fixing Telerik.Web.UI.dll errors.

  • Repair Windows: Make sure Windows is fully updated, then open Windows Terminal or PowerShell as an administrator (search for “PowerShell” in the Start menu, right-click it, and choose “Run as administrator”). This allows you to repair the Windows component store and run the System File Checker (SFC).

    Repair the Windows component store so SFC can pull clean files:

    DISM /Online /Cleanup-Image /RestoreHealth

    Scan all protected system files and automatically repair problems:

    sfc /scannow
  • Uninstall & Reinstall: On this DLL page, check the Company/Product section to identify the related app, then fully uninstall it. If you plan to continue using it, reinstall the latest version. Be sure to save or back up any important data before uninstalling. Windows or antivirus software may sometimes quarantine DLL files, especially if the DLL is unfamiliar or appears suspicious. Check your antivirus quarantine or logs to determine if this is the cause of your issue.
  • Download the DLL: Download the latest 32-bit or 64-bit version of the DLL directly from our repository using the download button above. Most users will need the 64-bit version, but if you are unsure, or if a 64-bit version is not available, you can install both the 32-bit and 64-bit DLLs. DLLme verifies DLLs that come from our admins, partners, and trusted affiliates. User-uploaded files may be verified later if a trusted source is confirmed.
  • Register the DLL: Most DLL files do not need registration, but some DLLs are COM components and must be registered to work correctly. If registration is required, open Windows Terminal or PowerShell as an administrator.

    Register the DLL (you can also drag the DLL file into the window to automatically fill in its full path): 

    regsvr32 "C:\path\to\Telerik.Web.UI.dll"

    If you are registering a 32-bit DLL on 64-bit Windows, use the 32-bit RegSvr32: 

    C:\Windows\SysWOW64\regsvr32 "C:\path\to\Telerik.Web.UI.dll"

    Or open Windows Terminal/PowerShell in the DLL’s folder and run: 

    regsvr32 Telerik.Web.UI.dll

How to Install Telerik.Web.UI.dll

To install Telerik.Web.UI.dll, place the DLL file in the appropriate Windows system folder or in the same folder as the application’s .exe file. If you are not sure which version (32-bit or 64-bit) to use, you can safely install both.

On 64-bit versions of Windows, place 64-bit DLL files in:

C:\Windows\System32\Telerik.Web.UI.dll

Place 32-bit DLL files in:

C:\Windows\SysWOW64\Telerik.Web.UI.dll

Or place the DLL file next to the application’s .exe:

C:\path\to\exe\Telerik.Web.UI.dll
