ARASS is using the C:\Program Files\Transport Canada folder (not :\Program Files (x86)\Transport Canada?). You can copy the content of C:\Program Files (x86)\Transport Canada to C:\Program Files\Transport Canada

Inside C:\Program Files\Transport Canada, you should have AjaxControlToolkit.dll, CLFPage.dll, TcMailerNet.dll, and the following folders: StreamTagFilter and CLFPagePlugin

• Inside your local .vs, make sure the applicationhost.config contains these lines inside the <modules> section

<modules>
  <add name="StreamTagFilter-2.0" type="Utility.IIS.StreamTagFilterModule, StreamTagFilter.NET.2.0, Version=1.0.5.0, Culture=neutral, PublicKeyToken=d3d707ec692e4024" preCondition="runtimeVersionv2.0" />
  <add name="StreamTagFilter-4.0" type="Utility.IIS.StreamTagFilterModule, StreamTagFilter.NET.4.0, Version=1.0.5.0, Culture=neutral, PublicKeyToken=d3d707ec692e4024" preCondition="runtimeVersionv4.0" />
</modules>

• If you are seeing any exclamation marks in the References for CLFPage , AjaxControlToolkit, TCMailerNet then add their references by pointing to their dll 's locations on C:\Program Files\Transport Canada, and make sure Copy Local is True. When Copy Local is True, then building the solution will add the dll copies to the bin folder.

• If the layout is still not fixed (see image below), this means the CLFPage.dll is not correct (calling the old stylesheets), please see below for the fix.
