⚠️ Newer server distributions, such as Windows Server 2025 , are explicitly not compatible and not approved for WinCC 7.5 SP2 deployments. 2. Microsoft SQL Server Dependencies
Running multiple Siemens engineering packages on the same workstation requires careful version matching to prevent DLL conflicts. TIA Portal Coexistence
Deploying WinCC in a virtual environment helps reduce hardware footprint and simplifies disaster recovery. Siemens officially supports WinCC V7.5 SP2 on the following hypervisors:
Note on Multi-User Limits: When using standard desktop operating systems like Windows 10 or Windows 11 as a multi-user server, the platform restricts connections to a . Server OS Support
Upgrading from WinCC V7.3 or V7.4 directly on the same OS machine requires a complete uninstallation of the older version before installing V7.5 SP2. 4. Virtualization and Hypervisors wincc 7.5 sp2 compatibility list
Deploying or upgrading a SCADA environment requires absolute certainty regarding software dependencies. The deployment relies heavily on the operating system, underlying database instances, and engineering extensions. Selecting an unsupported combination can trigger installation failures, broken database linkages, or runtime instabilities.
For a smooth experience, Siemens recommends a multi-core CPU and at least 8 GB of RAM for server systems. Minimum (Single-User/Client) Recommended (Server/Single-User) Dual-core 2.5 GHz Multi-core 3.5 GHz RAM Storage 1.5 GB (Installation) 10 GB (Work space) + Archive memory Resolution 1920 x 1080 (Full HD)
Professional/Enterprise/Ultimate (Limited support for specific client scenarios). Windows 8.1 (64-bit): Professional/Enterprise. Server Stations Windows Server 2019 (64-bit): Standard / Datacenter. Windows Server 2016 (64-bit): Standard / Datacenter. Windows Server 2012 R2 (64-bit): Standard / Datacenter.
By using the official Siemens Compatibility Tool and following the best practices outlined in this article, you can confidently plan your SCADA migration or new WinCC V7.5 SP2 project. As WinCC V7.5 SP2 approaches its eventual end of life, also keep an eye on its successors, , which offer extended support for Windows 10 and Windows 11. ⚠️ Newer server distributions, such as Windows Server
Supported via the Web Navigator plug-in, requiring a modern, patched browser version.
Beyond the operating system, the compatibility list serves as a roadmap for integration within the broader Siemens automation portfolio. In industrial settings, WinCC rarely operates in a vacuum; it must coexist with engineering tools like the TIA Portal and SIMATIC STEP 7. The compatibility documentation ensures that communication drivers, database interfaces, and optional packages—such as WinCC/WebNavigator or WinCC/Audit—are synchronized with the core Service Pack 2 updates. This synchronization prevents the "version mismatch" errors that can cripple a facility during a staged upgrade.
WinCC 7.5 SP2 is designed to coexist and integrate with several other Siemens software packages:

Comprehensive Guide to WinCC 7.5 SP2 Compatibility List Siemens SIMATIC WinCC V7.5 SP2 is a cornerstone SCADA system used extensively across industrial sectors for monitoring and controlling complex processes. To ensure system stability, security, and performance, it is crucial to install the software on a supported platform. The dictates which operating systems, database versions, and software components work optimally together.
You cannot decouple WinCC V7.5 SP2 from this specific SQL Server version. Upgrading the underlying SQL Server instance independently to a newer major version (like SQL Server 2019 or 2022) will break the WinCC runtime database connection. 3. SIMATIC Software Coexistence
