    I have a problem with intellisense not working in the code behind for my web project.  I have uninstalled and reinstalled both Visual Studio (2012 Premium) and Telerik packages.  The activity log (/Users/{MyProfile}/AppData/Roaming/Microsoft/VisualStudio/11.0/ActivityLog.xml) shows this error:

    CreateInstance failed for package [Telerik.Web.UI.VSPackage.VSPackage {plus version information}]

    I have a feeling this is the cause of intellisense not working.

    I'm working on a Windows 7 x64 platform with 8G of RAM.

    Any help would be greatly appreciated.

     I think the error is not related to InstelliSense. The log shows the Telerik VSExtensions (responsible for the Telerik Project Wizards) crashing. To fix it I recommend fully cleaning Visual Studio 2012 of the extensions before reinstalling them:

    1. Uninstall all Telerik extensions from Visual Studio 2012 | Tools | Extensions and Updates
    2. Ensure all Visual Studio instances are closed.
    3. Delete all direct subfolders of C:\Users\[username]\AppData\Local\Microsoft\VisualStudio\11.0\Extensions\ containing Telerik.*.dll assemblies.
    4. Reinstall them fron Extensions and Updates menu.

    IntelliSense not working with Visual Studio 2012 is a known issue. The following article suggests how to fix it (use asp:ScriptManager instead of telerik:RadScriptManager):

    Let me know If you need further assistance.

    All the best,
