Certificate Issue
When clicking on .vsto file it complains about an untrusted certificate which was used to sign the deployment manifest. Any suggestions?
Perhaps another installer other than ClickOnce could be used to deploy the vsto? Problems with Win7 Pro just reported, that I think comes to group policies on domain, that prevent the installation when not administrative user, because lack of trust.
@okoeth I had this same issue when I was trying to run the .vsto file after placing within the Prog files. However, I could succeed the installation placing the folder out of C:/. As @jabis said, could be an issue with administrative access.
Also I had to manually select each file and in the properties Grant access. (There is a button at the bottom).
