Pro Mode includes advanced features that are currently locked in the free mode version of PDQ Deploy. To use these new features you simply need to provide a key (trial or full) to PDQ Inventory. There is nothing new to install, all the features are already there. 

Choose which key you want, trial or full. After you obtain your key, go to File > Product License and copy/paste the key. This will unlock the features.

In addition to all the features of the Free mode, Pro mode provides the following:

• Schedule your deployments
• Multiple actions
• Email notifications
• Wake-On-LAN
• Target filters
• Pull file copy (targets of deployments will pull the installations files down)
• Throttle your bandwidth and other resource management tasks
• Link To dynamic target lists for recurring deployments
