The toolbox installation might fail if there is some registry that our installer fail to find. You will need to manually add the toolbox to the visual studio yourself if this issue occurs. 

We never got any report regarding Northwind issue, if you could give us more detail about the northwind issue or the toolbox issue, we will inform our installer developer of the issue 

I installed the WebTextEditor Manually, however I still can't get it to work.

There appears to be problems with the register SmartWebResourses

This is a brand new ASP project where all I have done is draged the control onto the page, and then

after I do the registration the follwoing resources get added: IsNet.WebUI.WebTextEditor, IsNet.WebUI.WebTextEditor.Resources, ISNET.WebUI.Resources

I then try and run the app and get 4 errors complaining that the resources IDataSourceControlSupport, IClientAction, IFlyPostBack, ISNet control are not referenced.

NOTE:The Northwind error looked liked the install was expecting northwind to exist on the target system (wich it does not)... it was a fairly generic error.

In order for the WebTextEditor to work correctly it will also need some resources from WebDesktop. Please add the ISNet.WebUI.WebDesktop.Resources.dll to your project bin folder.
