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.

Tips from Real Projects
A plant standardized every machine connection through one KEPServerEX instance; when the historian changed, not a single PLC project was touched. The connectivity layer is the firewall between the shop floor and every IT fashion.
