I have been Googling for a few days and seem to have only confused myself further. I will start off by saying that I am not a computer scientist and have VERY limited technical knowledge. I am trying to deploy an InfoPath form that has custom coded buttons. The form needs Full Trust and I am having trouble figuring out how to enable this. I am deploying the form locally as opposed to using a SharePoint/Web based solution. Each user will install the form on their desktop from either an email or USB drive. I have seen solutions that use the Publish to Installable Form, but that option seems to be missing from InfoPath 2013. I have also tried the official Microsoft recommendation of modifying the manifest and template files then repacking the XSN file. When I attempt to register the repacked XSN in visual studio, I get an access is denied error. I made sure that the file is not read only and I have tried running the code with admin privileges. I don't have the resources to obtain a digital certificate so I really need to figure out how to make the form installable to enable full trust once deployed. I have made a self signed certificate for testing but obviously that isn't a solution for other users. Any help would be greatly appreciated!
