    "No parameterless constructor defined for this object" with umbraco 5


    i try to install the latest Umbraco 5 version from codeplex on a 64bit Windows 2008R2 server. I installed the MVC2 and MVC3. But after calling the installation page "http://mydomain.tld/Install" i get the error message "No parameterless constructor defined for this object."

    I've got the same error.

    I've installed latest Umbraco 5 via Web PI. And when I go to http://localhost/Umbraco/Install the error occures. I try to reinstall Umbraco for a few times with the same result.

    Windows 7 x64.

    Reflector shows 'Umbraco.Cms.Web.Mvc.Controllers.BackOffice.InstallController' really doesn't have a parameterless constructor.

     Update: I resolve this issue by unintalling Umbraco and ASP.NET MVC 3. After that I install Umbraco via WEB PI and be able to create a simple site although with

    Error reading XSLT file: \xslt\umbTopNavigation.xslt

    error :)

    Yep me too. Downloaded the file, unzipped into a folder, pointed IIS 7 at it, and browsed to it.  Got the same problem.  Checked folder permissions and set everyone to full permissions (just to be sure instead of IIS_IUSRS, IUSR and NETWORK SERVICE.


    This is disappointing. I was rather looking forward to using it.
