Browser throws a "Cannot Create .net Editor" error.

Warning


Issue

When a schedules, reports, trend logs, loops, any calendar are loaded Internet Explorer is rejecting the control and will not host it.  IE will then throw a “Cannot Create .net Editor” error.  

Environment

  • .Net 4.51
  • WebClient
  • Internet Explorer

Cause

Microsoft has stopped allowing IE to host controls from .net 2.0 and 1.1 by default.

Resolution

In order for these controls you must do the following on all of your client machines:

 

  1. Open regedit
  2. Update the .NetFramework key as follows:
  3. On an x86 Operating System
  4. Add a DWORD attribute with the name EnableIEHosting to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework
  5. Set the value to 1
  6. On an x64 Operating System
  7. Add a DWORD attribute with the name EnableIEHosting to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework
  8. Set the value to 1
  9. Reboot the computer

At this point you should be able to start WebClient and run the .net editors without any problems.
