Unknown Server Tag nopCommerce:SearchBox

This was on my first ever run after installing nopCommerce

<div class="searchbox">
         <nopCommerce:SearchBox runat="server" ID="ctrlSearchBox">
         </nopCommerce:SearchBox>
     </div>

This code (above) is generating the error message in the topic title.

I removed this block of code (from \Modules\HeaderMenu.ascx) and the demo site appeared without further issues.
Even the Search page functions OK.

Any clues ...

Thx

The error indicates that you are missing the Register directive for the SearchBox control in the file: Modules\HeaderMenu.ascx

<%@ Register TagPrefix="nopCommerce" TagName="SearchBox" Src="~/Modules/SearchBox.ascx" %>

The following is the default Modules\HeaderMenu.ascx file from 1.90:

<%@ Control Language="C#" AutoEventWireup="true" Inherits="NopSolutions.NopCommerce.Web.Modules.HeaderMenuControl"
    CodeBehind="HeaderMenu.ascx.cs" %>
<%@ Register TagPrefix="nopCommerce" TagName="SearchBox" Src="~/Modules/SearchBox.ascx" %>
<div class="headermenu">
    <div class="searchbox">
        <nopCommerce:SearchBox runat="server" ID="ctrlSearchBox">
        </nopCommerce:SearchBox>
    </div>
    <ul class="topmenu">
        <li><a href="<%=CommonHelper.GetStoreLocation()%>">
            <%=GetLocaleResourceString("Content.HomePage")%></a> </li>
        <% if (this.ProductService.RecentlyAddedProductsEnabled)
           { %>
        <li><a href="<%=Page.ResolveUrl("~/recentlyaddedproducts.aspx")%>">
            <%=GetLocaleResourceString("Products.NewProducts")%></a> </li>
        <%} %>
        <li><a href="<%=Page.ResolveUrl("~/search.aspx")%>">

        <% if (this.BlogService.BlogEnabled)
           { %>
        <li><a href="<%= SEOHelper.GetBlogUrl()%>">
            <%=GetLocaleResourceString("Blog.Blog")%></a> </li>
        <%} %>
        <% if (this.ForumService.ForumsEnabled)
           { %>
        <li><a href="<%= SEOHelper.GetForumMainUrl()%>">
            <%=GetLocaleResourceString("Forum.Forums")%></a></li>
        <%} %>
        <li><a href="<%=Page.ResolveUrl("~/contactus.aspx")%>">
