Installation Notes
- Reboot the PC once after installation completes — this finalizes driver and service registration.
- If a controller or robot connection will be used, allow the software through the Windows firewall when prompted.
- Temporarily disable antivirus and Windows Defender real-time protection — installers that copy licensed components are frequently false-flagged.
- Run the installer as administrator and keep the default path unless your company standard requires otherwise.
- Do not connect any USB license dongle until the setup program has finished completely.
Frequently Asked Questions
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.
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.
Is a license dongle required?
Licensing is typically node-locked or dongle-based; a trial mode is usually available for evaluation.
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.

Tips from Real Projects
On a recent line-commissioning job, SIMATIC STEP 7 PLCSIM ran beside the physical controller for the first two weeks of startup, and every logic edit was proven offline before it touched steel. Two disciplines carried the project: library blocks versioned and tested on one pilot station before any update-all sweep, and trace files kept running so intermittent faults left evidence. One caution from the field: never convert an old project without keeping the untouched original beside it — some migrations are one-way doors.
