The "DLL and Scripts only" file (a.k.a. HOTFIX file) is a bare-bones upgrade option for our controls - they contain only those files that you need to replace in your project to upgrade to the new version of a Telerik control. If you are already using a Telerik product, there is no need to download the complete suite - download the "DLL and scripts only" version and follow the instructions below for applying the hotfix. The "DLL and Scripts only" file contains the following folders and files:

• bin folder - contains the DLL file(s)
• RadControls folder - contains the clients-side JavaScript and resource files for Telerik RadToolBar

If you are installing a Telerik product for the first time, we recommend that you download the complete package (EXE or ZIP file).

To update Telerik RadToolBar to a new version

1. Log in your Client.NET account.
2. Go to "My licenses" and click on "My Purchases" (or "My Free Trials" if you are a trial user).
3. Locate the control that you need to install, i.e. Telerik RadToolBar, and click on it.
4. Click on the "Download" tab and download the "DLL and Scripts only" file. If you have purchased the control, you need to download the file which has the Dev abbreviation in it.
5. Once the download completes, unzip the files at a convenient location.
6. If the upgrade is major (i.e. from v1.x to v1.x), check the Changes and Backward Compatibility section in this manual for further instructions.
7. Back up your application.
8. Close Visual Studio or any ither IDE which may lock the old assembly.
9. From the newly downloaded and unzipped files, copy the new DLL (located in the bin folder) to your web-application's bin folder. Replace the old dll.
10. [Optional. Follow this step only if you intend to use skins different from the default or if you plan to modify the JavaScript files
    Exceptions: Because of the specific control features, you will always need to copy RadControls for Telerik RadChart, Telerik RadEditor, Telerik RadSpell and Telerik RadWindow products. ]
    Copy the new RadControls folder to the root of your web-application. Replace all files and folders when asked. If you moved the RadControls folder through the RadControlsDir property to another location (different from the root), then locate the old folder and paste the new RadControls folder over it. Replace all files and folders when asked.
11. If you are using VS.NET, update the control's reference in your project to point to the new DLL.
12. Recompile your project.
13. If you have added the control in GAC, remove it by running a gacUtil to remove the old copy and then add the new one. More information on the topic can be located here: Add/Remove Telerik RadToolBar to the Global Assembly Cache
14. Run the project.
15. If you still get the older version of Telerik RadToolBar click here
    
    

    • Sometimes the .NET Framework wrongly caches the Telerik RadToolBar's DLL and therefore the update may seem to have failed. Try the following to ensure that this is not the case:
    • Terminate the aspnet_wp.exe process (from the Windows Task Manager)
    • Open a Windows Explorer and navigate to C:\Windows(WINNT)\Microsoft.NET\Framework\v[YOUR_VERSION]\Temporary ASP.NET Files
    • Delete all folders with names, corresponding to your Telerik projects, i.e. RadToolBar, etc.
    • Delete your Visual Studio web project cache(s) - it should be located in C:\Documents and Settings\[YOUR USER]\VSWebCache.
    • Delete your browser cache: Tools -> Internet Options -> Delete Files....
      

16. If you get a copyright message click here

    
    The copyright message appears only when using the trial version of Telerik RadToolBar (the Developer versions of Telerik's controls do not throw copyright messages).

    If you have purchased the control, then you have downloaded the wrong "DLL and Scripts only" file. Make sure you you download the proper, Developer "DLL and Scripts only" file. You will recognize it by the Dev abbreviation in the file name.
