Make the installer truly 100% silent
Right now, the agent installer still pops a number of CMD windows during a "silent" setup due to the amount of custom actions in the .msi file. These are all seemingly calls for regsrv32, and should be wrapped somehow to prevent the CMD window from appearing at all. CMD /c is not enough to suppress. Random windows popping up at the time of install prompts users to think something nefarious is occurring on their machine, and they end up calling in a support ticket.
