Summary:
When trying to view the Citect web client, the error message "Starting Citect Web Client Failed: Can not load citectweb.dll" is displayed in Internet Explorer:

 

Solution:
This error message has been seen when Internet Explorer is using the wrong version of the .Net Framework.

In previous versions of Internet Explorer there is a work around whereby a config file for IE is placed in the Internet Explorer folder in Program Files. This file "IExplorer.exe.config" can sometimes still exist and force IE to use version 1.1 of the framework.

Remove the config file, or update it to point to the correct version of the .Net Framework (at the time of writing, version 2).
