The first thing I would check would be that the Windows 11 version is not the latest 24H2, which is not tested for compatibility with WinCC 7.5. The exact version you can see with "Windows + R" and typing winver. Also, only WinCC 7.5 with SP2 is the one that can have compatibility with some versions of Windows. 11. I attach the excel that I have obtained from the Compability Tool in case you want to check it. I hope this comments help 🍀 Attachment WinCC_V7.5_compatibility-list_en_2025-03-13.xlsx (179 Downloads)

Does it work if you create a new test project. Can you set this one to Runtime or does it only appear with a special project? Check also if you turn off alarm and tagglogging in the startuplist of you project. Does it then go into runtime? Bye Murof
