    COMException after Package install

    1. Fresh local install of Umbraco 7.6.5 - Setup on SQL Server and startup of all basics going ok.

    2. First step after Umbraco install, going to packages to install Ucommerce.

    3. Install seems to go fine, DB get populated and log writes:

    INFO UCommerce.Umbraco7.Installer.Installer - Done Upgrading uCommerce.

    However, after reload the site throws a 500 with the following in the log and event viewer:

    ERROR Umbraco.Core.UmbracoApplicationBase - An unhandled exception occurred System.Runtime.InteropServices.COMException (0x8007000D): The data is invalid. (Exception from HRESULT: 0x8007000D) at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at System.Web.Handlers.AssemblyResourceLoader.EnsureHandlerExistenceChecked() at System.Web.Handlers.AssemblyResourceLoader.IsValidWebResourceRequest(HttpContext context) at System.Web.Security.FormsAuthenticationModule.OnEnter(Object source, EventArgs eventArgs) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

    I'm suspecting the culprit might be a malformed or corrupted change of the web.config, but im unsure how to debug further... :-( Any advice is appreciated.
