I am developing cdf files to give our customers and of course, there are dynamic contents in it and I get that warning message. I would like to edit the trusted folders, give the directions to the user how to do it. Is that possible? Otherwise, user has to put the cdf file inside those folders, trusted by default, but they are not really easily accessible.
