6. Once the download completes, run the installation. Notes:
   • the installer installs the assemblies in the GAC (C:\Windows\assembly).
      
7. If the upgrade is major (i.e. from one quarterly release to other quarterly release), please check the HELP manual and the relevant Changes and Backward Compatibility topics for each control as some new versions are not backwards compatible with the older ones.
8. Backup your application.
9. Backup all customized files such as custom themes, etc.
10. Locate and run the Project Update Utility from the installation folder (by default located in Start --> Programs --> Telerik --> RadControls for WinForms XX --> Tools).

2. UPDATING YOUR PROJECT MANUALLY

1. Follow steps 1 through 8 above.
9. From the newly installed files, copy the new DLLs (by default located in C:\Program Files\Telerik\RadControls for WinForms Q1 2008\bin) to your application's bin folder. Replace the old dlls.  
10. If using VS.NET, update the control's reference in your project to point to the new DLL and recompile.
11. 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.
12. Restore your customized files if needed.
13. Run the project.
