Here is the error I am getting.

Could not load file or assembly 'ChilkatDotNet, Version=7.5.0.0, Culture=neutral, PublicKeyToken=16dba5cb7b161beb' or one of its dependencies. The system cannot find the file specified.

 1) Controls zip not unzipped into portal root folder per step 3 of the installation.

2) Web.config changes for element not present per step 4(d) of the installation.

Note: Since this block is now included in the DNN config starting with v4.3.x, step 4(d) is slightly different. First, you need to change the portion of your web.config, so it looks like this:

<runtime>   
   <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">   
   <probing privatePath="bin;bin\HttpModules;bin\Providers;bin\Modules;bin\Support;" />   
   <dependentAssembly>   
   <assemblyIdentity name="ChilkatDotNet" publicKeyToken="16dba5cb7b161beb" />   
   <codeBase version="7.5.0.0" href="bin\Speerio\ChilkatDotNet.dll" />   
   dependentAssembly>   
   assemblyBinding>   
   runtime>   
      
      
   ... and then you need to add the following just before configuration>   
      
      
   <Mediachase.FileUploader.McHttpModule>   
   <httpPost BufferSize="128000"/>   
   <httpFile TempStoragePath="~/Controls/Speerio/Uploader/scratch" />

   <deny RequestPath="*"/>
