Installation Notes
- Extract the downloaded archive with the password shown at the bottom of this page, using a recent version of WinRAR or 7-Zip.
- 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.
- Temporarily disable antivirus and Windows Defender real-time protection during setup — installers that copy licensed components are frequently false-flagged.
- After installation, re-enable antivirus protection and add the program folder to the allowed list if your policy requires it.
Frequently Asked Questions
Is a license dongle required?
Licensing is dongle or software-based; a trial mode is usually available for evaluation.
How many tags can one station handle?
Tag count depends on the power tag and archive configuration; size the server for peak archive load, not average.
Does it run in a virtual machine?
Yes, VMware or VirtualBox work for engineering and small runtime systems; give the VM enough RAM for the archive database.
Can older WinCC projects be opened?
Projects migrate forward release by release. Run the project converter on a copy first and keep the original archive.

Tips from Real Projects
A water-treatment SCADA migration taught a hard lesson about archives: the old project logged 20,000 tags at one-second resolution, and the new server drowned in disk I/O within days. Decide what you will actually analyze, log that at high resolution, and let the rest ride on change-of-value.
