Ok I have followed the directions shown here http://help.infragistics.com/doc/ASPNET/2015.1/CLR4.0

And in my tool box I have a tab for the Infragistics tools but all the controls are greyed out.

 I tried to create a new toolbox tab and add the tools manually, but  it shows all of the with a check mark by them indicating they are already installed

 FYI: I don't know if makes any difference, but we do not have admin privileges on our dev boxes :(

Any thoughts?
