I've reciently installed Windows7, and, as the title says, there are some programs I can't install. What I've noticed is that they are "msi" files (I think) - don't know if this means anything or not. I get an error message (red "X") that says that the system admin doesn't allow such a file to be installed, but I'm the sys admin. I took a gander at the Admin Tools (Control Panel), but I don't understand most of what's there. Please help!
