Frequently Asked Questions
Can older projects be opened?
Projects migrate forward release by release. Keep a backup copy of the original project before converting it to a newer version.
Does it run in a virtual machine?
Yes, VMware or VirtualBox work for programming and testing; enable nested acceleration if you use the built-in simulator.
Is a license dongle required?
Licensing is typically node-locked or dongle-based; a trial mode is usually available for evaluation.
Which controller series is supported?
Check the release notes for the exact firmware matrix; each major version supports a defined controller range, and newer firmware usually requires a newer engineering tool.

Tips from Real Projects
A palletizing cell programmed entirely offline with FD on Desk II Pro 3.1 reached the floor needing less than an hour of touch-up per robot. What carried the job: every path annotated with named offline targets, home positions documented, and the signal handshake table agreed with the PLC team before the first jog. Don’t let anyone teach points around a singularity without reviewing the tool load data first — that is how wrist faults appear on otherwise perfect paths.
