Anyway, I share the attached WinCC V7.4 SP1 compatibility excel. From what I see, if I'm not mistaken with the version of Windows you mention, if it is the Pro, it is not compatible with version V7.4 SP1. There you will find the compatible versions. If it is not what I say, can you share a screenshot of the exact OS version? And a screenshot of the error message that you tell us about? Best regards!
