- Run the installer as administrator and keep the default path unless your company standard requires otherwise.
- If a controller or robot connection will be used, allow the software through the Windows firewall when prompted.

- After installation, re-enable antivirus protection and add the program folder to the allowed list if your policy requires it.
Frequently Asked Questions
Do old WinCC projects convert?
Classic projects do not convert automatically; screens are rebuilt with migrated tag and alarm structures.
What replaces VBS scripting?
Unified uses JavaScript/TypeScript server and client scripting; plan retraining for classic script libraries.
Is a license dongle required?
Licensing is software-based with dongle options; trial mode is available for evaluation.
Does it run in a virtual machine?
Yes, engineering and runtime run in VMware; give the VM GPU resources if you use heavy 3D scenes.

Tips from Real Projects
The first Unified line at an automotive supplier shipped late because the team ported legacy screen clutter one-to-one. The second line took half the time: they rebuilt twenty key screens instead of two hundred legacy ones, and operators rated the new system higher. Migrate the philosophy, not the pixel count.
