The easiest way to deploy Crypt-o is to use Software installation service of your Windows domain's Group Policy. Use Crypt-o setup packaged as .msi for that purpose. To fully automate the deployment, you need to install the Crypt-o Group Policy Administrative Template and configure Crypt-o Server connection parameters.
Other way of the deployment is to run an unattended Crypt-o installation on workstations. To do that use command line parameters of the setup program.
