We are announcing the End of Life (EOL) of the optional PDQ Agent beta from our existing products. See this blog post for more information https://www.pdq.com/blog/pdq-agent-status-update/
You receive this error after attempting to deploy a package to a computer in PDQ Inventory with the Agent set to External: Modified Packages can't be deployed to External Agents.
Currently, only unmodified Auto Download packages can be deployed to External Agent computers.
- The Auto Download package cannot have Pre or Post steps.
- The Auto Download package cannot be converted to a standard package.
- Any custom-built packages will also fail with this error.
In the future, functionality will be expanded to allow deploying customized packages to computers with a PDQ Inventory Agent in External mode.
