How do I uninstall the agent?

Uninstalling the Pixel Plow agent is a different procedure depending on whether you have it installed on a Mac or Windows machine.

Mac-

Simply drag the agent from your Applications folder to the Trash bin.

Windows-

Exit any running instance of the agent.  Then, delete the entire agent install directory.  This may be “c:\pixelplow” by default, if you installed older agent builds initially, so it would be there unless you chose a different folder during installation.  Newer agents allow you to place them wherever you wish.
