I’ve done it from a deferred DLL CA using the CreateSymbolicLink() API before.
Blair From: Scott Palmer Sent: Saturday, January 25, 2014 5:32 PM To: General discussion for Windows Installer XML toolset. "runas" seems to be useless for installer purposes. For one: I can't have a console window pop up where a user is forced to enter their password. Second: It may run as a particular user, but not with *all* of their privileges, i.e. not as an Administrator. I'll make it an open challenge.. I've spent a couple days trying. If anyone could confirm one way or the other, if it is possible or impossible to create a symbolic link from an installer with nothing more than the usually UAC prompt appearing. Note that if you run msiexec as an administrator (from a "Run as Administrator" command prompt), then everything works. Obviously that totally ruins the user experience and goes against the whole point of UAC. What is so scary about symbolic links that this is a privileged operation anyway??! It's particularly mysterious since once the symbolic link is created your don't need any special privileges to delete it!
