Below is a guide to the most effective solutions to get WinCC 7.5 back online. 1. Verify OS and WinCC Compatibility

Before diving into deep technical fixes, ensure your version of Windows 10/11 is compatible with your specific WinCC 7.5 Service Pack (SP).

Navigate to the WinCC installation directory (usually C:\Program Files (x86)\Siemens\WinCC\bin ). Locate and run as an administrator. Restart your computer and try opening WinCC again. 3. Check SQL Server (WinCC Instance)

WinCC relies heavily on a local SQL Server instance. If this instance isn't running or was installed incorrectly, the "basic application" will fail to start.

A known conflict exists between Windows 10 version 20H2 and older WinCC 7.5 installations. This is often caused by an outdated Microsoft Edge version interfering with the SQL Server installation.

Use the Siemens Compatibility Tool to verify your OS build number against your WinCC version. For example, WinCC 7.5 SP2 might require specific updates (like Update 15) to run on Windows 10 22H2. 2. Run the Reset_WinCC.vbs Tool
