3rd Party Control Will Not Install On Windows 8/IE 10

We have a .NET Framework 2 web-based app that uses the txTextControl text editor. We have a built-in script that sets CASPOL for our users. We are getting an "Access Denied" error when we try to install this control on Windows 8/IE 10 machines, as shown in the image below. I have installed the 3.5 Framework (which also installs 2 and 3), but still no joy getting the control to install.

Any ideas and advice are greatly appreciated, as more and more of our users are wanting to use our system on Windows 8 machines!

Solution

  • They've published some information here to help with this because of the .NET 4.5 changes (which is on Win8)

    Check out: http://www.textcontrol.com/en_US/blog/archive/20130119/

    Since .NET 4.5, the security model has been changed and hosting these controls
is blocked in Internet Explorer by default. The previous behavior can be 
restored by setting the EnableIEHosting value of the registry subkey
HKLM/SOFTWARE/MICROSOFT/.NETFramework to 1.
