    Install Umbraco 4 on Windows 10

    I had a Umbraco 4 Site that I use to debug on a Windows 8 machine, and it worked well... Now I recieved a new Windows 10 machine (ASP.NET 4.6), and Umbraco BackOffice does not opening, not Front Office does.

    The error I get is : Object reference not set to an object

    [NullReferenceException: La référence d'objet n'est pas définie à une instance d'un objet.] umbraco.cms.presentation.login.OnPreRender(EventArgs e) +340 System.Web.UI.Control.PreRenderRecursiveInternal() +88 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +4775

    I wonder if Umbraco v4 is compatible with Windows 10 (with .NET 3.5 installed)

    Hi Serhio

    I don't think Umbraco 4 is able to run on Windows 10 - I spoke with a former colleague of mine yesterday that mentioned that they needed to have virtual machine setup running Windows 8 in order to be able to service those clients running on very old Umbraco 4 installations.

    So you probably need to do the same I guess.

    Hope this helps.
